Exit code is 0 for `ERROR: <module-a version-1> has requirement <module-b version-1>, but you'll have <module-b version-2> which is incompatible.`
See original GitHub issue- Operating system:
Linux nemkin-testing 4.9.0-11-amd64 #1 SMP Debian 4.9.189-3 (2019-09-02) x86_64 GNU/Linux
Python2 example:
- Pip version:
pip 19.3.1 - Python version:
Python 2.7.13
Python3 example:
- Pip version:
pip 9.0.1 - Python version:
Python 3.5.3
Original issue
I am building Docker images where one of the steps is to install some pypi packages. I found that the Docker image build is successful, however looking at the output logs I see the following printed quite often:
ERROR: <module-a version-1> has requirement <module-b version-1>, but you'll have <module-b version-2> which is incompatible.
Reproducing with Python2
Using Python2 I am able to reproduce the issue with a small example. I found out that pip2 reports an exit code of 0, even when the above error is present, which causes Docker to report success on the build.
See the following example:
- Pip version:
pip 19.3.1 - Python version:
Python 2.7.13

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-proce

Questions
- Why is pip2 reporting an exit code of 0 with this error present in the logs:
ERROR: <module-a version-1> has requirement <module-b version-1>, but you'll have <module-b version-2>? - Since python2 is almost already deprecated, I don’t care about issues with pip2. Can you show me an example where a similar error message is triggered using python3?
- If such an example exists, and the exit code is 0 there too, why is that the case?
- If such an example doesn’t exist was this type of error removed from pip somewhere along the line?

Just want to explain this part:
The different is not Python 2 vs 3, but that you have different versions of pip in those two environments. The one in your Python 2 is newer. The same error should be visible if you upgrade pip in your Python 3 environment.
Tested the same install command in the Python3 example with pip 19.3.1 and it triggered the error, thanks @uranusjr for pointing it out! 😃
