Installation in virtualenv via pip fails

[raymondEhlers]

When trying to install xrootd in a virtualenv on Ubuntu 18.04.4 with python 3.7 via pyenv, the installation fails at the last step with python3.7: command not found.

The abridged error is:

$ pip install xrootd
.......
    -- Installing: /clusterfs4/rehlers/software/pyenv/versions/3.7.6/lib/python3.7/site-packages/pyxrootd/include/xrootd/private/XrdCl/XrdClFileSystemOperations.hh
    ./install.sh: line 35: cd: ../bindings/python: No such file or directory
    pyenv: python3.7: command not found

    The `python3.7' command exists in these Python versions:
      3.7.6

    Note: See 'pyenv help global' for tips on allowing both
          python2 and python3 to be found.

I added a symlink in env/bin from python3 -> python3.7and then was able to install successfully. Edit: I spoke too soon. With the symlink, I actually get:

    ./install.sh: line 35: cd: ../bindings/python: No such file or directory
    python3.7: can't open file 'setup.py': [Errno 2] No such file or directory

Since I have to use pyenv on this system, I suspected that it might be the underlying issue, but it seems to work with pyenv if I'm not in a virtualenv. Since it fails on changing the directory, I guess it must be related to finding files in the virtualenv.

Thanks!

When I install it outside of my virtualenv instead, I get a library issue:

>>> from XRootD import client

I believe this was fixed as part of our Debian focused release.
