Compose: docker-compose pip install fails with pip 10.0.0

[soundsgoodsofar]

Description of the issue

We're running docker-compose on CentOS. The pip version when installed with --upgrade changed to 10.0.0 in the last couple days and our docker install (pip install docker-compose) began failing with the following message. It appears that pip 10.0.0 has increased the version dependency of package requests to 2.6.0, which is incompatible with the default docker-compose installation.

Stacktrace / full error message

$ pip install docker-compose
...
  Found existing installation: requests 2.6.0
Cannot uninstall 'requests'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Additional information

OS version / distribution, docker-compose install method, etc.

I have the same issue. Workaround for now would be not to upgrade the pip to 10.x.

I also have same and downgrade pip to 9.0.3.

Also an issue on RHEL 7.4. Temporarily working around the problem by doing the same as @hermesian, using:

sudo pip install --upgrade --force-reinstall pip==9.0.3

After looking at this more closely, it looks like this is mostly a pip / Linux distribution issue:

• https://github.com/pypa/pip/issues/4805
• https://github.com/pypa/pip/issues/5247

My takeaway here is that it's not Compose's responsibility to fix, nor would we be able to even if we wanted to.

Downgrading pip is probably a reasonable course of action for the short term (other reasonable options: virtualenv, Compose binaries). In the long term, the way yum installs some Python packages probably needs to change.
