Prophet: Installing with PyPI - Errno 39

[andmib]

I'm trying to update fbprophet in my Docker container based on Debian GNU/Linux 8 (jessie).

I get the following error when I run pip install -U fbprophet:

Exception:
Traceback (most recent call last):
  File "/opt/conda/lib/python3.6/shutil.py", line 544, in move
    os.rename(src, real_dst)
OSError: [Errno 18] Invalid cross-device link: '/opt/conda/lib/python3.6/site-packages/numpy' -> '/tmp/pip-_b5qhid2-uninstall/opt/conda/lib/python3.6/site-packages/numpy'

During handling of the above exception, another exception occurred:

Any suggestions?

This seems to be an issue with pip when /tmp/ is on a separate filesystem (due to being a virtual environment):
https://groups.google.com/forum/#!topic/python-virtualenv/GPXAi9WZKIs

In the thread there they suggest a workaround by setting the TMPDIR environment variable that should work. Also seen here:

I'm going to close this since it does seem to be external to Prophet, but feel free to re-open if you're still having issues with this.

connecting dots for future travelers, if anyone's experiencing this on virtualbox running a linux guest with a vboxfs share from the host, there's a virtualbox bug causing this same error with pip
