I am trying to follow this guide to install python modules however i don’t seem to have virtual environment or pip installed so im trying to get those to continue.

Python 2.7.5 is installed on my cpanel, i want to install extra modules for my scripts. I download:

get-pip.py using curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

I then try running the python file with:

python get-pip.py

It starts but fails at: Installing collected packages: pip, wheel.
With error message:

Could not install packages due to an EnvironmentError: [Errno 30] Read-only file system: ‘/usr/lib/python2.7/site-packages/pip’

If i use sudo python get-pip.py

I get the following error message:

jailshell: sudo: command not found

Thanks

  1. I’d the same problem in my ChromeOS and I couldn’t solve it running chmod -R in my site-packages folder. To solve it I had to install pip only for my user running:

    python get-pip.py --user
    

    The only problem is that you have to run pip as a python module python -m pip, but you can create an alias inside your .bashrc.

    # ~/.bashrc
    #
    # ...
    alias pip="python -m pip"

  2. Run this issue on my local MacOS with pip2.7, trying to install jwt package

    sudo pip2.7 install jwt pyjwt[crypto]
    ...
    ERROR: Could not install packages due to an EnvironmentError: [Errno 30] Read-only file system: '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/...'
    ...
    ..
    

    No sudo or trying to chmod the read-only file helped. Solved installation with –user parameter:

    sudo pip2.7 install --user jwt pyjwt[crypto]
