pip install is not installing executables in /usr/local/bin

Question

I recently setup a new Ubuntu 16.04.2 machine. I'm trying to install some python packages, but all the packages are getting installed at /usr/local/lib/python2.7.10/bin instead of /usr/bin or /usr/local/bin.

Installing collected packages: git-review

  changing mode of /usr/local/lib/python2.7.10/bin/git-review to 755
Successfully installed git-review-1.25.0

What's the problem here?

Solution 1

I had to remove the pip package that was installed by apt.

sudo apt remove python-pip

And then install pip again according to instructions on their website - https://pip.pypa.io/en/stable/installing/.

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

Looks like pip from Ubuntu's default repository is not same as one distributed by pypi.

Solution 2

Open a terminal and run:

pip uninstall git-review
sudo pip uninstall git-review
sudo pip install --prefix /usr/local git-review
git review --version

The last command should output something like git-review version 1.25.0.

Does running git review work?

No, I had to manually invoke it from /usr/local/lib/python2.7.10/bin/git-review.

/usr/bin shouldn't be used because it's used only for dpkg/Apt packages. Does pip install --install-option="--prefix=/usr/local/bin" git-review put it in /usr/local/bin and have it working correctly?

[ronakg]

Nope. It still goes at the same location.

[Chai T. Rex]

OK, I found a slightly-different option that works here. Try my answer below.

That did work, but now I'm getting another error. $ git review Traceback (most recent call last): File "/usr/local/bin/git-review", line 7, in <module> from git_review.cmd import main ImportError: No module named git_review.cmd

[Chai T. Rex]

Sorry, I'm not seeing that, so I'm not sure how to fix it.

[ronakg]

Actually I removed the installed pip using sudo apt remove python-pip and then reinstalled pip according to instructions here - pip.pypa.io/en/stable/installing

[Chai T. Rex]

Its use is cautioned there: Be cautious if you're using a Python install that's managed by your operating system or another package manager. get-pip.py does not coordinate with those tools, and may leave your system in an inconsistent state.

[ronakg]

Yes exactly @chai-t-rex.

You can do the last part without a temporary file with sudo python <(wget -O- https://bootstrap.pypa.io/get-pip.py 2>/dev/null)
