Invalid version number: 0.3e

[BercziSandor]

I wanted to use your package from PyCharm (poetry env.) like this:
from bitbucket.client import Client

PyCharm asked me if I wanted to install package, yes, as usual.
After that I got this:

Using version ^0.3e for BitBucket

• Installing bitbucket (0.3e)

Hello, that's right, we are using bitbucket name for imports but the this library is called bitbucket-python in pypi.org so PyCharm is trying to install a different library, which is not the same as this one.

The only solution is to install with command
pip install bitbucket-python

[BercziSandor]

Hello, yes, you are right.
In my case: poetry add bitbucket-python
