When using sudo to run pip "pip: command not found" but it's installed

sudo easy_install pip

Searching for pip

And then when I run

sudo pip install -U pyyaml nltk

I get:

sudo: pip: command not found

If you install pip from the Ubuntu repositories pip will work with sudo (I have used pip this way on 12.04 through to 14.04).

sudo apt-get install python-pip

Your pip is installed in /home/nyzlfc/.local/bin, which is not in the sudo path and with a good reason. Just add ~/.local/bin to your path and step away of sudo as it's unnecessary.

I had the same problem, and the reason I had this problem (on Debian) is that I installed python3.2 and python3-pip and as such, I really didn't have a pip executable, I also didn't have a pip3 executable. I have pip-3.2 executable.

As such I would also recommend doing:

sudo pip

and then pressing the tab to see the autocomplete options.

First check your $PATH variable using the echo command:

$ echo $PATH

If /usr/local/bin is missing, edit the hidden file .profile, located in your home directory. If this file is missing, edit .bash_profile instead.

Add as very last PATH statement the following line:

PATH=$PATH:/usr/local/bin
