Maybe a simple question, but I cannot figure it out. I work within Visual Studio Code on a MacBook. Within a directory I create a virtual environment and have activated that with source .venv/bin/activate scripts and everything works fine.
In the terminal I see (.venv) (base) gaston#MacBook-Pro WebScraping %
When I start visual code another time and open this same directory I do not see the (.venv) so I again give manually the command to activate.
My question is there a way to activate the virtual environment automatically when opening the directory?
VS Code Default Python Interpreter Path
You can do this in a number of ways. If your goal is to have the virtual environment selected immediately at the launch of VS Code, you will have to target that virtual environment as the Python Interpreter in VSC.
https://code.visualstudio.com/docs/python/environments
System Preferences->Settings->Python: Default Interpreter Path
You'll want to point it to your virtualenv Python installation, likely something like:
envFolder/bin/python3
VS Code Launch Configuration Python Interpreter
You can also set a specific launch configuration so that VSCode will still use your system Python instance by default; however, specific launch configurations will have the virtual environment specified.
https://code.visualstudio.com/docs/python/debugging
I did something within settings and now it works.
When I open VSC now it opens the directory and the right environment, just the way I wanted it.
Took me some while to figure what finally did the trick:
I opened settings Command + , typed env in the search box. Scrolled through the results until I saw:
Python > Terminal: Activate Env In Current Terminal
and checked the checkbox. That solved my problem.
Using pycharm, I finished my first python program.
I am attempting to run a bat file with Windows Scheduler.
The python script has lots of dependencies. They are available in the virtual environment I am using.
I tried activating my virtual environment using the activate.bat file in the directory of the venv.
The code of the scheduled bat file looked like this:
C:\Users\PavelWorkXPS\Anaconda3\envs\TestEnv\Lib\venv\scripts\nt\activate.bat "D:\Dropbox\Toolkit\Python\Unusual_Options_Activity-ToS\main.py" pause
When running this, Pycharm would launch because it is my default .py extension handler.
I modified the bat file to use the interpreter python.exe from within the virtual environment folder, hoping it would have access to the dependencies.
C:\Users\PavelWorkXPS\Anaconda3\envs\TestEnv\python.exe "D:\Dropbox\Toolkit\Python\Unusual_Options_Activity-ToS\main.py" pause
Output would tell me it still can't see the dependencies.
I used this earlier stackoverflow post for help, but it only explained the reason
why pycharm was opening by itself.
Conda was the reason for the problem. When I switched to doing it with a plain virtual environment, it stored all the downloaded repos in a folder inside of the folder with the script. Then I setup the bat file and all worked fine.
I am getting the following error message when attempting to execute Python code in PyCharm:
Cannot run program "/Users/x/.virtualenvs/untitled/bin/python" (in directory "/Users/x/PycharmProjects/untitled"): error=2, No such file or directory
I made sure everything was updated and restarted my computer, but I still get the same error. I have no idea what the problem is.
Edit
I just opened my terminal and was faced with this error message:
virtualenvwrapper_run_hook:12: no such file or directory: /usr/local/bin/python3.7 virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3.7 and that PATH is set properly.
I have no idea what happened here. I certainly didn't touch any of this.
Edit 2
If I execute Python3 --version, I get Python 3.8.5.
Edit 3
I followed this, but this error remains:
Edit 4
This is the current state:
I think this is related.
If it helps at all this is what my venv settings looks like.
I don't have the answer as to why it happens, but I find its usually when renaming the project.
In the past i've recreated the project and copied the project files directly from the old folder to the new one in a file explorer (not pycharm) and its fixed it.
This Error Occurs because when you rename the file you need to update the file path name also...
.......Solution...........
click on Edit Configurations (near the green 'run' play button)
Where it says 'Script Path' at the end of the string is where you find the name of
your file
Change the name to the updated file name
Probably the root library has been deleted or corrupted.
I suggest to delete the venv library in explorer and then write the following commands in the terminal
> C:\Users\MY\PycharmProjects\pythonProject>py -m venv venv
> C:\Users\MY\PycharmProjects\pythonProject>cd venv\Scripts
> C:\Users\MY\PycharmProjects\pythonProject\venv\Scripts>activate
For me, it was the symbolic link in the project. Running this command fixed it:
xcode-select --install
You may want to check the contents of the 'activate' script inside your venv. It contains a few hardcoded, absolute paths to files and directories within your environment. If you change something in that environment, e.g. move a file or directory around, these paths can easily become invalid.
Similar issues can arise when you, for example, create a virtual environment inside a virtual machine, then open files in PyCharm from outside that machine.
For me, the problem was that I created the virtual environment through the PyCharm settings and ticked "Inherit global site-packages", I think. Once I removed the virtual environment and created it using the old fashioned way, i.e.
mkvirtualenv projectname --python=python3.10
everything fell into place.
With a Python project opened, whenever I open the integrated terminal in Visual Studio Code it's automatically activating the virtual environment. I'm sure that's done by VS Code because I can find this command in the bash history of that terminal:
source <project-directory>/venv/bin/activate
I don't want the virtual environment to be activated. How can we prevent VS Code from doing that?
Add "python.terminal.activateEnvironment": false to your settings (globally to your user settings if you never want it, otherwise your settings.json file which is found in .vscode directory; this folder is found in your workspace directory if this is a per-workspace thing for you; docs).
If you open the vscode terminal first and then select python interpreter, then it won't activate the python environment. This answer works in vscode 1.44.0 with pyhton 3.8.1. I haven't tested with other versions. However, if you have any files or workspace open you need to close that first to close the python interpreter. You don't need to make any changes in settings.
I have recently installed the Anaconda distribution on Windows 7 (Anaconda 3-2.4.0-Windows-x86_64). Unlike IDLE, I can't right-click and open a py file in the Spyder IDE. I will have to open Spyder first and then navigate to the file or drag and drop it in the editor. Is there any way to open the file in the editor directly from Widows Explorer?
With the current version of Anaconda (4.1.0) you can simply right-click on a python script in Windows File Explorer and choose "Open with". The first time you do this you need to select "Choose default program" and then browse to spyder.exe in the Script directory in your Anaconda installation. Also make sure that the "Always use the selected program to open this kind of file" is unchecked and then click OK. From now on spyder.exe will always be listed as one of the options when you select "Open with" from the right-click menu in Windows File Explorer.
I have had a similar problem with another piece of software that I use.
My work around for this problem is to set the file association for .py files to C:\Anaconda\Scripts\spider-script.py via the Open with dialog. If you now try to open your File.py by double clicking you'll receive an error like
~\file.py is not a valid Win32 application.
This can be resolved by editing the spyder-script.py registry key:
HKEY_USERS\S-1-5-21-3559708500-1520960832-86631148-1002\Software\Classes\Applications\spyder-script.py\shell\open\command
and replacing the default value "C:\Anaconda\Scripts\spyder-script.py" %1 with "C:\Anaconda\python.exe" "C:\Anaconda\Scripts\spyder-script.py" %1. Use the search function for this key if the path isn't the same for your machine, and of course use the appropriate path for your python installation. spyder-script.py should now execute in a python shell.
From the docstring of ftype,
...Within an open command string, %0 or %1 are substituted with the file name being launched through the association.
(Spyder maintainer here) This functionality is available as part of our Windows installer. In other words, if you install Spyder with it, then you'll see a new entry in the Open with menu of the Windows Explorer that allows you to open Python files directly on Spyder.
Unfortunately, it's not possible for us to do the same for other installation methods (i.e. when using Anaconda or pip). That's why it's necessary to resort to different hacks, as the ones mentioned in other answers here, to have this functionality for them.
What is working very well for me in Windows (10), is associating the *.py files with a batch file (let's say "SpyderBATCH.bat") containing this line :
[ANACONDA_FOLDER_PATH]\pythonw.exe" "[ANACONDA_FOLDER_PATH]\cwp.py" "[ANACONDA_FOLDER_PATH]" "[ANACONDA_FOLDER_PATH]/pythonw.exe" "[ANACONDA_FOLDER_PATH]/Scripts/spyder-script.py" %1
Where [ANACONDA_FOLDER_PATH] has to be replaced with the full path to the Anaconda folder (usually under "Program Files").
What Windows does, when double-clicking on a python script (let's say "file.py"), is pass to SpyderBATCH, as parameter number %1, the full path to "file.py".
Then Spyder is launched and displays the script "file.py" in the editor view.
I figured I would post my solution for this as well.
I have Spyder installed in multiple different environments. You can't simply call the spyder-script.py script without errors, because the environment must be activated.
#echo off
call [YOUR_CONDA_PATH]\Scripts\activate.bat [YOUR_CONDA_PATH]
call conda activate [YOUR ENVIRONMENT]
call start [YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\pythonw.exe "[YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\Scripts\spyder-script.py" %1
You can remove the second line and remove the environment extension from the third line if you have Spyder installed in your base environment.
Hopefully for anyone experiencing any weirdness with the other solution, this one will do the trick by activating the environment correctly.
The solution from JoeB152 worked perfectly for me!
If you are interested in adding the spyder icon (or any other) to the .py-files and if you would like to avoid the cmd-pop-up, I found out the following workaround which is feasible without admin rights:
Download the portable version of Bat To Exe Converter (I used v3.0.10).
Open your custom .bat-file in the Bat to Exe Converter.
In the options settings, activate "Icon" and give the path to the respective icon (for me it's in: .../AppData/Local/Continuum/anaconda3/Scripts/spyder.ico).
Set Exe-Format to Invisible (no empty cmd window would pop up anymore)
Convert your .bat-file to an .exe-file.
As usual, set to open .py-files with the newly created .exe.
Enjoy!
Environment:
Windows 10,
Conda 4.8.2,
Spyder 4.0.1,
Python 3.7
This problem is related to anaconda installation defaults - it does not register itself in PATH by default an dicourages users to do so. After proprly registering all directories in path, spyder.exe works as expected.
How to know, what to register?
locate and activate.bat an run it in cmd, then run echo %PATH% and manually register all directories mentioning anaconda.
Alternatively, reinstall anaconda with PATH registratin enabled.
Then you can associate .py files wit spyder.exe and association will work.
System: Windows 11, Python 3.9.7 (Installed through Anaconda3)
This solution will allow you to double click .py files and have them open in the Spyder in the environment of your choice, but does NOT associate .py files with the icon for Spyder.
I'm answering because it took me over an hour to understand & piecemeal together all the (great) solutions that are provided in this thread to get something that works (thanks Martin Sorgel, JoeB152 and Max-K).
NOTE: Some commentors above say to use a Bat-to-Exe converter & that will let you get the icon too.. but, DON'T! All of the ones you're finding via google have got some bad malware in them and my computer ended up deleting the .exe's I was making using that method because they had a Trojan in them.
Full Solution:
STEP 1: Make a .bat file that will launch Spyder in a specific environment.
1.1 Open a plain text editor (e.g. Notepad, etc.) and copy/paste the text below into it.
#echo off
call [YOUR_CONDA_PATH]\Scripts\activate.bat [YOUR_CONDA_PATH]
call conda activate [YOUR ENVIRONMENT]
call start [YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\pythonw.exe "[YOUR_CONDA_PATH]\envs\[YOUR ENVIRONMENT]\Scripts\spyder-script.py" %1
Update [YOUR_CONDA_PATH] in the text above with the path to Anaconda3 on your computer. Mine was C:\Users\myusername\Anaconda3\ & yours is likely similar.
1.2 Save this new file as spyderlaunch.bat and place it on your computer somewhere that you'll NEVER move it (otherwise you'll have to do STEP 2 each time you move this file. I save mine in a python_env_settings folder where I keep info on what packages I installed manually in my different environments).
NOTE: JoeB152 says you can remove the second line and remove the environment extension from the third line of the text above if you have Spyder installed in your base environment. I'm not sure if this works...
1.3 Make sure your new .bat files works! It works if when you double click on spyderlaunch.bat, that it launches and opens Spyder in the environment you want it to! (Spyder will show the environment it opens in on the bottom right hand side: ).
STEP 2: Tell your computer to associate (i.e. open) all .py files with the spyderlaunch.bat file you just created.
2.1 Open an Anaconda Terminal with "run as an administrator" (by right clicking on the application) and run the following 2, separate commands. Update[PATH_TO_YOUR.batfile] to wherever you saved spyderlaunch.bat in 1.2.
assoc .py=Python
ftype Python="[PATH_TO_YOUR.batfile]" "%1" %*
Errors?
If you don't run the Anaconda Terminal application as an administrator you will be denied access to associate .py=Python. If that's not your issue, then check that the spaces and quotation marks are exactly where they appear above. In particular, you may want to make sure there is a space in between the quotation marks around [PATH_TO_YOUR.batfile] and those around %1.
I was unable to find a spyder.exe on my installation of conda. However in my users/.anaconda/navigator/scripts I found a spyder.bat file. Using this to open the file opens an anaconda prompt and shortly after spyder will open the file. The file icon is broken but it works for me. Hope this might help.
(Comment in relation to the responses by JoeB152 and Jessica Haskins - I am new, so I cannot leave comments)
I found that their suggested .bat file works once you copy-paste the following file from A to B:
A) C:\Users\USERNAME\Anaconda3\Scripts\spyder-script.py
B) C:\Users\USERNAME\Anaconda3\envs\ENVRIONMENT_NAME\Scripts\
...where ENVIRONMENT_NAME is the name of your environment, such as main or test.
The .bat file contains:
#echo off
call C:\Users\bloggsj\Anaconda3\Scripts\activate.bat C:\Users\bloggsj\Anaconda3\
call conda activate C:\Users\bloggsj\Anaconda3\
call start C:\Users\bloggsj\Anaconda3\envs\main\pythonw.exe "C:\Users\bloggsj\Anaconda3\envs\main\Scripts\spyder-script.py" %1
Then associate .py files with that .bat file (e.g., via the 'Open with...' dialogue).
Alternatively, you could try using in the last line of the .bat file the file path: "C:\Users\bloggsj\Anaconda3\Scripts\spyder-script.py"
Get Spyder by itself:
https://docs.spyder-ide.org/current/installation.html
Set your default file opener to your newly installed spyder
To be able to add packages:
Make sure Anaconda is installed.
Go to Spyder preferences
Go to Python interpreter
Select: "Use the following Python interpreter"
Select file path with Anaconda and hit apply
Now you should be able to open files directed using Spyder and update your environment using Anaconda.
I made a batch utility spy.bat for this (not in the Anaconda directory)
spy.bat
call E:\Anaconda3\Scripts\activate.bat E:\Anaconda3
e:\Anaconda3\python.exe e:\Anaconda3\Scripts\spyder-script.py %1
Then, I associated the .py file type in Windows with this batch file as:
Right click any .py
Choose 'Open With' -> 'More Apps' -> 'Search on your PC' ->'select spy.bat'
In the spy.bat:
E:\Anaconda3 is my Anaconda installation directory.
First line starts the environment (Anaconda prompt).
Second line starts the spyder-script. %1 is to open the pyscript you want to open.
