On windows 10, virtualenv installs but that's where it stops. Using the "one basic command", "virtualenv MyPathandFile", only gives the error: "'virtualenv' is not recognized as an internal or external command".
Tried "python virtualenv" or variations of it doesn't work either. These give the message: "no such file or directory" Are there other packages required? It was installed in an administrator cmd window. Tried uninstalling/reinstalling as well.
And finally, is there another, easier way to make virtual environments?
It sounds like it is not in your path. Can you go to your python installation directory and look for a folder called Scripts? There should be a virtualenv.exe script there. If it is there, add the path to that folder to your path environment variable.
You can also try python -m virtualenv and see what that returns.
See my Scripts folder (notice virtualenv at the bottom):

I am trying to create a virtual environment in VS code to make a flask app. After I run the command in the VS code terminal pip install virtualenv everything downloads find but I get the error WARNING: The script virtualenv.exe is installed in
C:\Users\NAME\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Then when I try to create my virtual environment by using this command virtualenv env I get the error
virtualenv : The term 'virtualenv' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
Are you using Python from the Windows Store? You'd better avoid it.
You can download the python from the official site.
And then create the virtual environment through venv.
You can refer to official docs for more details of the virtual environment created.
This is happening because the directory (as mentioned by you)
C:\Users\NAME\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\Scripts' which is not on PATH.
is not added to your PATH
Consider this link Add to the PATH on Windows 10 and add the directory to the PATH.
It's gonna solve your problem.
The same issue happened to me it solve it as said above.
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.
correction
i edited the environment variable to path Scripts, but in the command prompt on typing the pip command it does not shows up the package installation
python\scripts location picture
While executing the pip command in the command prompt, it shows pip is not recognized as an internal or external command, operable program or batch file.
I tried setting environment variables and all other alternative solution still I am not able to solve it. I recently noticed pip.exe file missing from python/scripts module.
Is that reason to show up this error? if it is yes, how will I install it manually?
You should add the full directory to the Scripts folder to your PATH environment variable. When you run commands in a command prompt, Windows will search through the folders listed in PATH.
Assuming you are on Windows 10:
Press the start button then search "Environment Variables"
Click the "Edit Environment Variables" option.
Click the "Environment Variables" button in the box that pops up.
Scroll down and find the PATH variable, double click it.
Click "New"
Paste in the path to the Scripts folder.
Save it and exit, then restart the terminal. Now pip will be recognized.
Finally I solved it.I used python 3.8.3 version.Not folder named "Scripts" in this version.I just delete this version and reinstall python 3.7.8 version and then pip is here :D
I know this has been solved, but another way of dealing with this is to create an empty file in the 'Scripts' folder and rename it to pip.bat. Then add the following code:
python -m pip %*
Which simply passes all the arguments of the pip command to python.
So if I load a conda environment and want to use conda to install a package (or whatever else), I have to specify conda.exe.
What I expect to work:
(randomenv) λ conda --version
The system cannot find the path specified.
What actually works:
(randomenv) λ conda.exe --version
conda 4.5.4
Further complicating things, the following:
(randomenv) λ where conda
C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\conda
C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\conda.bat
C:\ProgramData\Anaconda3\Scripts\conda.exe
Is the first entry supposed to be C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\conda.exe and the environment got setup wrong or something?
Edit:
We're now in to usage breaking issues. I can't use deactivate, because deactivate doesn't have a .exe extension.
Per usual, where deactivate turns up:
C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\deactivate
C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\deactivate.bat
C:\ProgramData\Anaconda3\Scripts\deactivate
C:\ProgramData\Anaconda3\Scripts\deactivate.bat
Even more hilariously frustrating:
(randomenv) λ C:\Users\[USERNAME]\AppData\Local\conda\conda\endevs\randomenv\Scripts\deactivate
The system cannot find the path specified.
and then it gets even better:
(randomenv) λ cd C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts\
C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts
(randomenv) λ ls
2to3.exe* conda* easy_install.exe* epylint-script.py iptest3.exe* ipython-script.py pip-script.py pygmentize-script.py pyreverse.bat symilar.exe*
2to3-script.py conda.bat easy_install-script.py idle.exe* ipython.exe* isort.exe* pydoc.exe* pylint.bat pyreverse.exe* symilar-script.py
activate* deactivate* epylint.bat idle-script.py ipython3.exe* isort-script.py pydoc-script.py pylint.exe* pyreverse-script.py wheel.exe*

C:\Users\[USERNAME]\AppData\Local\conda\conda\envs\randomenv\Scripts
(randomenv) λ deactivate
The system cannot find the path specified.
How can't it find a file that's in the current directory?
Edit2:
Found the following issue on GitHub which says that exiting an environment requires that you activate root. That isn't working either, because activate can't be found just like all the other functions listed above.
This just happened to me. Here is what I found out.
Within the scripts folder of my environment were three scripts:
activate.bat
conda.bat
deactivate.bat
along with three more without the .bat extension that were bash scripts. In each case, all they did was a delegate to the globally installed copy of the same tool using an absolute path name.
When given a command, such as "conda" at the prompt, Windows will search for a .com, .exe or .bat file to execute, taking the first one it finds. Because activating an environment adds it's locations to the head of the path, the first instance windows will find is the .bat file within the environment, which will be executed.
In my case, the .bat files had the wrong absolute path, and were trying to delegate to a global copy that did not exist, hence the error message. Even if you were in the environment script directory, you would still get the message because it's not the .bat file that the message refers to, but the program the .bat file delegates to.
When specifying conda.exe, you are specifically asking for the .exe file, which means the .bat file will not be found and run, and therefore the global copy is found, which of course works.
I fixed it by changing the path inside each of the .bat files to the proper path to the tool, according to the output of where x, which fixed the problem.
I had the same problem. Interestingly, when I set up a fresh environment the activate / deactivate commands work fine.
I compared the script folder for this environment with the broken environment. The broken environment had activate / deactive files in the scripts folder just like yours, but the working environment did not.
By deleting the extraneous scripts (deactivate, conda, activate, .pt-postlink), the broken environment now works again.
I suspect something else I've done corrupted this folder. Possible a package I installed is the culprit? If I figure it out I'll post back.

How to add to the PYTHONPATH in Windows, so it finds my modules/packages?
(23 answers)
Closed 5 years ago.
I recently installed Python 3.6 for my Windows 10 (64bit) and I want to use pip, but before to install that, I need to execute the following command using the downloaded get-pip.py program:
python get-pip.py
Somehow this doesn't work and I get the following message from Command Line:
'python' is not recognized as an internal or external command,
operable program or batch file.
(I get the same message when I want to execute some pip commands)
I tried a lot of "solutions" for installing pip, like downloading files from https://bitbucket.org/pygame/pygame/downloads/ but nothing happened, I got the messages...
Could you explain to me why the Command Line doesn't know these commands and how can I install them?
No need for admin access:
The reason the error is arising is because python is not in your PATH (meaning it can be called from any directory in the prompt). You can check that its not in the PATH by typing the following:
echo %path%
which will return lost of different directory paths, but not the one to where you have python installed.
To add python to this (and get rid of your error), follow these steps:
Open up control panel.
Go to System. (skip to this step with: Win+Break )
Go to the Advanced tab at the top.
Click on Environment Variables at the bottom.
In the section User variables for ___, add a new one with New.
In this pop-up add the name : path and value : C:\Python34 (or wherever it is installed).
Hope this helps as this is what I did to get python to work from any directory in the command prompt!
Open your CMD as administrator and type PATH (prints the output of your system PATH Variable). There have to be a PATH directing to your Python Installation directory. Only with that system Path your cmd knows where python.exe is and search there for python.
Normally the Python Installation Setup asks if you want to set a Python Environment PATH Variable. Maybe run the setup again and watch out for that option. And I think there was a checkbox to automatic install pip for python.
If you want to set the Path Environment Variable use this:

If you want to manually install pip with GET-PIP you have to download get-pip.py first and then run it with python.
Download get-pip from here.

commands and how can I install them?
This happens when Python executables are not added to PATH.
#xyres provided a nice link on how to do this.
I want to use pip, but before to install that, I need to execute the following command
using the downloaded get-pip.py program:
pip should be bundled with the official Python installer, so there should be no need to get it from other sources
