can`t install whoosh alchemy

Question

I can`t seem to install whoosh alchemy for the life of me. reference: http://pythonhosted.org/Flask-WhooshAlchemy/ . Anyway, i'm following http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world and at the part where i'm trying to install whoosh-alchemy.

I'm typing in any of these 3

flask\Scripts\pip install flask-whooshalchemy==0.55a 
flask\Scripts\pip install flask-whooshalchemy
flask\Scripts\pip install flask-whooshalchemy==0.55

The error I get is the following:

Downloading/unpacking flask-whooshalchemy

    Running setup.py (path:C:\users\ray\microblog\flask\build\flask-whooshalchemy\setup.py) egg_info for package flask-whooshalchemy

'requirements.txt')).xreadlines()],

 AttributeError: '_io.TextIOWrapper' object has no attribute 'xreadlines'

I have no idea how to solve this at all... I'm trying to google this but haven't found any luck whatsoever. Maybe my google-fu is just terrible. Much appreciation for any help.

Answer 1

I found this pull request on Flask-WhooshAlchemy's github which talks about pip installs failing due to xreadlines call like in your error log. Try installing it directly from github where that pull request has been merged.

Here's the command to do that - pip install git+https://github.com/gyllstromk/Flask-WhooshAlchemy.git
