Using pip3 with sudo permission problem in Ubuntu 16.04

  • 772

I have Python3 and Python2 and also pip and pip3 for various python version package installation.

I want install a ZMQ library in Python 2 and 3, I did it in python2 as well with the following line:

sudo pip install zmq

But when I using pip3 for ZMQ installation on Python3 I have a problem:

$ pip3 install zmq
Collecting zmq
Collecting pyzmq (from zmq)

Installing collected packages: pyzmq, zmq
Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/usr/local/lib/python3.6/dist-packages/zmq'
Consider using the `--user` option or check the permissions.

Then when I used sudo before pip3:

$ sudo pip3 install zmq
sudo: pip3: command not found

[NOTE]:

$ pip --version
pip 18.0 from /home/benyamin/.local/lib/python3.6/site-packages/pip (python 3.6)

$ pip3 --version
pip 18.0 from /home/benyamin/.local/lib/python3.6/site-packages/pip (python 3.6)

$ which pip
/home/benyamin/.local/bin/pip

$ which pip3
/home/benyamin/.local/bin/pip3

$ sudo which pip
/usr/local/bin/pip

$ sudo which pip3
$ # no output

It seems that my pip is for Python3.6!

Any help would be greatly appreciated.

  1. First remove your local pip:

    /home/benyamin/.local/bin/pip3 uninstall pip

    Install it using apt:

    sudo apt install python3-pip

    or for "python2":

    sudo apt install python-pip

    then run:

    sudo pip3 install zmq

    you can also update pip using:

    sudo pip3 install pip --upgrade

    Alternative solution is to creat an alias:

    alias pip3='sudo /home/benyamin/.local/bin/pip3'

  2. Open the terminal and type:

    sudo apt install python3-pip   
sudo -H pip3 install --upgrade pip

    Create a symbolic link at /home/benyamin/.local/bin/pip3 which references to file /usr/local/bin/pip3.

    cd /home/benyamin/.local/bin/
rm pip3
sudo ln -s /usr/local/bin/pip3 /home/benyamin/.local/bin/pip3

    Check location of the pip3 executable file and pip3 version.

    which pip3  
pip3 --version

    Install zmq.

    python3 -m pip install --user zmq
