Why does "pip install" inside Python raise a SyntaxError?
(7 answers)
Closed 3 years ago.
when i type:
import numpy as np
i get this error:
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import numpy as np
ModuleNotFoundError: No module named 'numpy'
i tried to install like :
pip3 install numpy
but this error comes up on the word 'install':
SyntaxError: invalid syntax
i'm working on python 3.7.4 on windows8 32bits
i know it might be trivia but i'm just starting with python
Did you install pip first? If not, follow this:
Download get-pip.py to a folder on your computer.
Open a command prompt and navigate to the folder containing get-pip.py.
Run the following command:
python get-pip.py
You can verify that Pip was installed correctly by opening a command prompt and entering the following command:
pip -V
You should see output similar to the following:
pip 18.0 from c:\users\administrator\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)
Go to the folder that your pip is located and run your command:
cd c:\users\administrator\appdata\local\programs\python\python37\lib\site-packages\pip
pip install numpy
you should first quit the command line of python and then type pip install numpy in the cmd
First, check are you outside the command line, if yes then
Try
python -m pip install --upgrade pip
then
python -m pip install numpy
If it did not work, try adding python and pip full path in the commands.
One simple way of doing this is by using PyCharm, which can be downloaded for free.
Simply open your project in it, or create a temporary one, go to settings, project settings, and then to project interpreter. Here you can add your current python interpreter or create a new one, and then just press the add button to add libraries into that interpreter.
Now when you use that interpreter in or out of PyCharm, you will have access to any of those libraries you added.
This is not the best way of doing this, however, it is a sure way of making it work, and PyCharm is a great IDE for Python.

I am a very beginner for vscode and python and computer stuff in general.
I am having trouble importing pandas into vs code, and none of the previous posts was helpful for me since I literally can't understand it and can't follow their steps.
I am gonna show you what I have done so far.
First, I open the vscode and open terminal (powershell)
Second, I type pip3 install pandas and it successfully install pandas
For example, I ran that command again, it gave me "Requirement already satisfied"
enter image description here
Third, as it seemed pandas is installed correctly, I type py to open python in the terminal and type import pandas as pd
But, it gave me :
import pandas as pd
Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'pandas'
enter image description here
I really don't know why it is happening and what to do to fix this.
I will appreciate any help you can give me.
Thanks,
Make sure you are using the same interpreter as the one you installed the pandas library with.
Run the following code to print out the python interpreter you are currently using
import sys
print(sys.executable)
Copy the full path of the interpreter and install the pandas library for it using the command
C:\Users\Admin\AppData\Local\Programs\Python\Python310\python.exe -m pip install pandas
Modify the above path to the path you just got
It can also be done in the interactive window of the terminal
try pip install pandas instead of pip3
use cmd or git bush instead of powershell
use virtual environments in the current working directory:
open vscode on new folder
Terminal > New Terminal: (make shure it's cmd not Powershell)
pip install pipenv (on cmd)
pipenv install pandas
close vs code, open it again on the same folder
Terminal > New Terminal (cmd)
pipenv shell
py
I just started learning Python, and successfully downloaded Python 3.5. I attempted to download/upgrade PIP 8.1.2 multiple times using get-pip.py, which I ran (successfully I think) but when I attempted to execute python get-pip.py
I got the error code:
File "<stdin>", line 1
python get-pip.py
^
SyntaxError: invalid syntax
I understand that pip is included in python but the pip website requires users to upgrade pip which I don't think I can since any pip commands lead to syntax errors, and do not produce the same output that most tutorial sites show. I have tried to find different ways to fix it, but I can't figure out whats wrong aside from pip not being on the computer in the first place or corrupted. Thank you for your assistance.
You won't need to upgrade pip if you just downloaded python 3.5, go to where you have your Python3.5 file and open the folder Scripts, you will find pip.exe. Open powershell and use the cd command to move to the folder containing pip.exe. From here you can use pip install to get modules.
Open Windows Powershell
PS C:Users\you> cd C:\path\to\scripts\folder\containing\pip
PS C:\path\to\scripts\folder\containing\pip> pip install module
Not sure what you are asking. If you want to run python get-pip.py do it in a windows command prompt, not in the python interpreter. But I do not know why you would want to do that.
You already have pip; there is no need to run get-pip. Upgrading can be done by pip itself.
But the reason you are getting errors is that all these commands, including pip itself, should be run at the command line, not in the Python interpreter.
I have installed pip and ez setup. I also checked the system path and I can see the module in the folder structure. Still when i try to run pip command, I get an Import error saying no module named pip. I am running 32bit python on a windows7 machine
Just be sure that you have include python to windows PATH variable, then run python -m ensurepip
After running get_pip.py with python embed you have to modify your pythonXX._pth file. Add Lib\site-packages, to get something like this:
pythonXX.zip
.
Lib\site-packages
# Uncomment to run site.main() automatically
#import site
If you don't you will get this error:
ModuleNotFoundError: No module named 'pip'
or
python-3.8.2-embed-amd64\python.exe: No module named pip
λ pip
Traceback (most recent call last):
File "runpy.py", line 193, in _run_module_as_main
File "runpy.py", line 86, in _run_code
File "python-3.8.2-embed-amd64\Scripts\pip.exe\__main__.py", line 4, in <module>
ModuleNotFoundError: No module named 'pip'
λ python -m pip
python-3.8.2-embed-amd64\python.exe: No module named pip
This issue occurs with me while I was trying to upgrade pip version.
It was resolved with the following commands:
python -m ensurepip
The above command restores the pip and below mentioned upgrades it.
python -m pip install --upgrade pip
What solved the issue on my case was go to:
cd C:\Program Files\Python37\Scripts
And run below command:
easy_install.exe pip
Follow steps given in https://michlstechblog.info/blog/python-install-python-with-pip-on-windows-by-the-embeddable-zip-file/. Replace x with version number of Python.
Open the pythonxx.__pth file, located in your python folder.
Edit the contents (e.g. D:\Pythonx.x.x to the following):
D:\Pythonx.x.x
D:\Pythonx.x.x\DLLs
D:\Pythonx.x.x\lib
D:\Pythonx.x.x\lib\plat-win
D:\Pythonx.x.x\lib\site-packages
try to type pip3 instead pip.
also for upgrading pip dont use pip3 in the command
python -m pip install -U pip
maybe it helps
turned out i had 2 versions of python on my laptop
both commands worked for me
python -m ensurepip
py -m ensurepip
both with another installation path
c:\tools\python\lib\site-packages
c:\program files (x86)\microsoft visual studio\shared\python36_64\lib\site-packages
only the first path was in my %PATH% variable
First make sure that python is added in environment variable.
Try checking the version of pip or pip3. Use these commands to check.
For pip:
pip --version
For pip3:
pip3 --version
If you can see any version of pip and still not able to use it, then run the following command.
python -m ensurepip
This ensures the pip in your system.
Running these 2 commands helped me:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
If you wrote
pip install --upgrade pip
and you got
Installing collected packages: pip
Attempting uninstall: pip
Found existing installation: pip 20.2.1
Uninstalling pip-20.2.1:
ERROR: Could not install packages due to an EnvironmentError...
then you have uninstalled pip instead install pip.
This could be the reason of your problem.
The Gorodeckij Dimitrij's answer works for me.
python -m ensurepip
I found this post while looking for a solution for the same problem. I was using an embedded python distribution. In this case, the solution is to uncomment import site in the file python<version>._pth.
The ensurepip module was added in version 3.4 and then backported to 2.7.9.
So make sure your Python version is at least 2.7.9 if using Python 2, and at least 3.4 if using Python 3.
I'v solved this error by setting the correct path variables
C:\Users\name\AppData\Local\Programs\Python\Python37\Scripts
C:\Users\name\AppData\Local\Programs\Python\Python37\Lib\site-packages
I was facing same issue and resolved using following steps
1) Go to your paython package and rename "python37._pth" to python37._pth.save
2) curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
3) then run python get-pip.py
4) pip install django
Hope this help
I've solved this error downloading the executable file for python 3.7.
I've had downloaded the embeddeable version and got that error.
Now it works! :D
The method I'm going to tell might not be the correct way to do it. But this method solved my issue. I tried every solution on youtube and StackOverflow methods.
If you have two python versions installed. Delete one. I have the python 3.8.1 and 3.9.0 versions installed. I deleted version 3.9.0 from the C directory.
Now go to the control panel > System and security > System > Advanced system settings.
Click on 'environment variables'.
Select the path and click on 'edit'
Now, add the path of the python and also the path of pip module. In my case it was c:\python38 and c:\python38\scripts
This method solved my issue.
Instead of Python zip install python by python installer. It fixed the issue for me.
I am trying to install EasyGui on Python 3.3 and I don't see to have it. I had gotten it to work with Python 2.7 but not for 3.3.
I follow the instructions from their website:
Unpack the archive file into a temporary directory
Open a console window and navigate to the temporary directory.
At the command prompt, enter the command:
python setup.py install
But I keep getting this error when I use the command 'import easygui':
Traceback (most recent call last):
File "/pyshell#0/", line 1, in
import easygui
ImportError: No module named 'easygui'
For Python 3 you need to call python3 when installing it, so instead of
python setup.py install
you must do
python3 setup.py install
Just add "easygui.py" to your site-packages directory. It will work with any editor. I am using Coderunner, and I had the same problem. It took me an hour to figure it out :)
easy. type pip3 uninstall easygui then pip3 install --user easygui
I am trying to install Twitter-Python and I am just not getting it. According to everything I've read this should be easy. I have read all that stuff about easy_install, python setup.py install, command lines, etc, but I just don't get it. I downloaded the "twitter-1.9.4.tar.gz", so I now have the 'twitter-1.9.4' folder in my root 'C:\Python27' and tried running
>>> python setup.py install
in IDLE... and that's not working. I was able to install a module for yahoo finance and all I had to do was put the code in my 'C:\Python27\Lib' folder.
How are these different and is there a REALLY BASIC step-by-step for installing packages?
1) Run CMD as administrator
2) Type this:
set path=%path%;C:\Python27\
3) Download python-twitter, if you haven't already did, this is the link I recommend:
https://code.google.com/p/python-twitter/
4) Download PeaZip in order to extract it:
http://peazip.org/
5) Install PeaZip, go to where you have downloaded python-twitter, right click, extract it with PeaZip.
6) Copy the link to the python-twitter folder after extraction, which should be something like this:
C:\Users\KiDo\Downloads\python-twitter-1.1.tar\dist\python-twitter-1.1
7) Go back to CMD, and type:
cd python-twitter location, or something like this:
cd C:\Users\KiDo\Downloads\python-twitter-1.1.tar\dist\python-twitter-1.1
8) Now type this in CMD:
python setup.py install
And it should work fine, to confirm it open IDLE, and type:
import twitter
Now you MAY get another error, like this:
>>> import twitter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\twitter.py", line 37, in <module>
import requests
ImportError: No module named requests
Then you have to do kinda same steps in order to download the module requests.
Looking at the directory structure you have, I am assuming that you are using Windows. So my recommendation is to use a package manager system such as pip. pip allows you to install python packages very easily.
You can install pip here:
pip for python
Or if you want the windows specific version, there are some pre built windows binaries here:
pip for windows
Doing python setup.py install in IDLE will not work because that is an interactive python interpreter. You would want to call python from the command line to install.
with pip, you can go to the command line and run something like this:
"pip install twitter-python"
Not all python packages are found with pip but you can search using
"pip search twitter-python"
The nature of pip is that you have to type out the exact name of the module that you want.
So in a nutshell, my personal recommendation to get python packages installed is:
Install pip executable
Go to the command line
Type "pip search python_package"
Find the package you want from the list.
Type "pip install python_package"
This should install everything without a hitch.
Installing Python Modules clearly states you need to install the packages from command line, not the Python interpreter IDE (like IDLE):
For Windows, this command should be run from a command prompt window
(Start ‣ Accessories):
setup.py install
You mention the python setup.py install command, which intends calling python interpreter already and wouldn't make sense to run within interpreter.
You need to set the Windows system path variables to include c:\Python27 and C:\Python27\Scripts.
You do not need to set PYTHONPATH nor use any bat files.
Path c:\Python27 will tell Windows where python.exe is
Path c:\Python27\Scripts will tell Windows where pip is
Run pip from Windows command line (do not use Idle)
Basically, with python3.4.3, you just have to do two things to be able to use twitter:
1.python -m pip install -U pip
then once pip is updated (as it comes preinstalled). you do the second step:
2. pip install twitter
this will install twitter package.
Today, after using pre method, I could not use it again (as per my post yesterday). So I tried another way that's simple and cool and hope would work always (on my pc at least):
...Python34>cd scripts #command prompt change die where pip is
...Python34\Scripts>pip install fabric #in this dir, use pip
Awesome (for me at least) although the package I wanted could not be 'perfectly' installed, yet another pythovery.
