I have installed Python 3.11 with pip. I install a module (I have been using pyperclip) and then continue to use it without problems. I go back to command prompt line and suddenly pip is not a recognized internal or external source. The file location is the same, both are on the PATH environment variable, nothing has changed. The only evidence that it ever existed is the python -m ensurepip command which returns pip satisfies requirements. I am at my wits' end, two days straight of tackling this issue. I just want a working pip.
I have checked the variable paths, wiped all Python downloads from every corner of my PC, un- and re-installed until the cows come home, been through every checklist and every forum, and nothing has worked.
I'm trying to get up and running with Python 3.5.2 and various packages on a server I work on, but don't have root privileges for. I installed Python to my home, and that seems to be working. I'm trying to set it up so I can install packages to that Python installation (ie ~/lib/python3.5/site-packages) via pip, but I cannot get it working.
Even after adding ~/lib/python3.5/site-packages to $PYTHONPATH, no luck.
Running pip install pandas, I get the error /usr/local/bin/python3.5: bad interpreter: No such file or directory , so it's still looking in the wrong spot. It should be looking at ~/bin/python3.5. Setting an --install-option="--prefix= argument doesn't change the problem.
Is this possible to do?
Try this:
pip3 install --user "library name"
I've been working with Python for a little while now but have come to absolutely detest installing new modules. It always seems to take me a full work day to install one additional module. This last happened with mpl_toolkits and now it is happening with gdal.
The main issue seems to be that easy_install/pip/get-app aren't saving a file in the correct location and so Python (I'm using Spyder) can't find it. How do I install a module in a location so that Python can find it?
I have been reading guides, articles, manuals and Stack Overflow articles all day now and I feel this needs a new question as I can't find an answer.
It is installing fine, it's just Python (and I) can't find it
It's not in the /lib/python2.7/site-packages folder, which seems to be the Python default, although half the modules that do work aren't in there when I list it
I installed using:
sudo apt-get install gdal-bin
I also tried with:
pip install gdal
but this fails with the error:
Command "python setup.py egg_info" failed with the error code 1 in /tmp/pip-build-NWJT2f/gdal/
I looked for the files using
dpkg -L gdal
and then added the file path this said into Spyder's preferences option for PYTHONPATH, but it still couldn't find it and so I'm guessing this is wrong.
I have read the official documentation of PYTHONPATH, but it's very short and doesn't really explain it at all.
I recommend trying anaconda or miniconda, which manage environments and install packages - it 'just works'.

I recently installed Python for Windows 10 and need to use pip command to install the requests package.
However, whenever I try to use pip in cmd it just freezes my command prompt.
Using CTRL + C, CTRL + D or any command like that to cancel it does not work either, the prompt just freezes like its waiting for input or something, but I get no output or any clue about what to do.
I have set the PATH variable correctly, and my computer finds pip and launches it, but it just freezes. I have also tried reinstalling Python countless times and manually reinstalling pip but nothing seems to do the trick.
I had exactly the same problem here (Windows 10.0.10240). After typing just "pip" and hitting enter, nothing else happened on the console. This problem was affecting including other .exe compiled python related scripts like mezzanine-project.exe.
The antivirus AVAST was the culprit (in my case) !!!
After disabling AVAST files module (or uninstalling AVAST) pip started working again.
i didn't think i had the same issue as #Marcio, but the longer it went on, it turned out i did.
In avast, goto the settings, goto Active PRotection, go to File System Shield and add an exclusion for
C:\Python27\Scripts
should work without a reboot, did for me, I was having issues with the Virtualenv.exe which is in that folder.
Try to use easy-install insted of pip it works in the same way.
#eryksun provided what I think should be the answer to this question. I also have had the command prompt hang whenever I try to use pip, but I do not want to use easy_install. The solution (from #eryksun) was to use python -m pip install package_name. This works great for managing python packages in windows 10.
Marco's answer worked perfectly but the actual solution to the problem is that you should write your pip commands using python -m pip instead of just pip
so your command will be python -m pip install requests
I had this exact problem with the numpy module. The only way I could fix it is by following the steps found here: Installing NumPy and SciPy on 64-bit Windows (with Pip)
The steps were to
Download the appropriate precompiled wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/
Type pip install /path/to/module.whl
This worked perfectly for me. Hope this helps anyone else with this exact issue.
Well, when you run python -m pip, it actually starts pip.exe as a child process, so in the end it freezes the same for me, although it runs a bit longer...
Worse is that the pip.exe process is completely zombie, no way to kill it even with ProcExpl....
I had the same problem. Just disable your antivirus and it should work.
Thanks to #Marco Del Toro's answer, using easy_install worked for me: I could install the packages I needed for my project. I also managed to fix pip using easy_install so pip also works for me now. The solution to fixing pip was: easy_install pip.
This answer was posted as an edit to the question Pip not working on windows 10, freezes command promt by the OP Olof H under CC BY-SA 3.0.
If you have a certain network it can block pip for installation. For my case I used my own network without VPN.
and thanks to anyone who gives some of their time to consider my problem.
What I need help on is for someone to give me a simple and accessible explanation on how to install that module. I have never, ever used anything from PyPi before, I have only heard of pip after looking up PyCallGraph.
I'm not a programmer first, I'm doing an accounting internship and am using python to write scripts to help me speed up some processes, at the urging of a colleague who himself uses python. I write scripts using Notepad++ and execute them through IDLE.
I'm currently working on optimizing a script I wrote and came upon PyCallGraph while checking this very site on tips on how to do so.
I tried the very minimalistic instruction of just doing "pip install pycallgraph" just about anywhere I could think of, including cmd.exe, to no avail. Runing get-pip.py directly seems to have worked for installing pip, though.
Otherwise I can always just stick with the cProfile printout and write-off using modules needing such an install, although that saddly seems to be quite a few...
Step 1: Install PIP
Open terminal (cmd.exe, PowerShell, whatever)
Download get-pip.py and place it in the working directory of your terminal
Install PIP by invoking python get-pip.py
Confirm that PIP was installed correctly by invoking command pip (should display help if success)
If pip didn't work, make sure your PATH environment variable has been set up correctly. In typical Windows installations pip is installed under c:\Python27\Scripts. Make sure this folder is included in PATH.
Step 2: Install your library with PIP
Invoke pip install pycallgraph
PIP installs the library and it can be now used from Python
