ImportError: No module named packaging.version

I tried to re-build docker-airflow, and I get the following error:

ImportError: No module named packaging.version

Looks like the version of pip is pip 1.5.6 whereas upgrading to pip 9+ seems to fix the issue. (cf. pypa/setuptools#937).

[imsickofmaps]

You can workaround this in the mean time by inserting && pip install setuptools==33.1.1 \ in above && pip install Cython \ in the Dockerfile

[puckel]

Or adding && python -m pip install -U pip \ before Cython

[floer32]

@puckel I don't think -U pip would do it now ... cos I just had to do this:

$ pip install setuptools==33.1.1
Collecting setuptools==33.1.1

  Found existing installation: setuptools 34.2.0
    Uninstalling setuptools-34.2.0:
      Successfully uninstalled setuptools-34.2.0
Successfully installed setuptools-33.1.1

As you can see, I had to uninstall 34.2.0, then install 33.1.1... upgrading setupstools and pip wouldn't tdo the trick. So I think @imsickofmaps is right that 33.1.1 is the one, when getting this specific traceback.

(I could be totally wrong, I popped over here from a totally different project as I searched for the traceback.)
