Installation Fails Because of __version__ Import (v0.6)

See original GitHub issue

c88b376 tried to make things easier to manage by doing from flask_user import __version__ as flask_user_version in However, that has an undesirable consequence: users who don’t already have passlib installed could face an ImportError, preventing installation of Flask-User.

To reproduce (ensure passlib is not already installed):

$ pip install --no-cache-dir Flask-User==0.6.17
Collecting Flask-User==0.6.17 (from -r requirements.txt (line 13))
  Downloading Flask-User-0.6.17.tar.gz (62kB)
    100% |████████████████████████████████| 71kB 6.0MB/s
    Complete output from command python egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-c6f9o6kh/Flask-User/", line 5, in <module>
        from flask_user import __version__ as flask_user_version
      File "/tmp/pip-build-c6f9o6kh/Flask-User/flask_user/", line 7, in <module>
        from passlib.context import CryptContext
    ImportError: No module named 'passlib'

Command "python egg_info" failed with error code 1 in /tmp/pip-build-c6f9o6kh/Flask-User/

Note that if the packages are cached, it could also appear to work fine, which is why --no-cache-dir is needed.

Hm, I can’t quite find this 0.6.19 release anywhere? It seems that git tags haven’t been created since the 0.5 series, but I can’t find a commit fixing this in (or releasing 0.6.19) in either the master or 0.6.x branches? And pypy still seems to list 0.6.17 as the latest version. I might be ignorant on how this works and I might just need to be more patient, but it seems I’m missing something here?

I’m so sorry. I apparently was overwhelmed, and forgot to release the v0.6.19 build to PyPi. I’ve fixed this.
