Import Error for Flask-Bcrypt with Google App Engine: ImportError: No module named bcrypt._bcrypt

[Dan Rubio via StackOverflow]

I am trying to deploy my flask application to Google App Engine. After much toil I've finally been able to upload my libraries but when I use the command dev_appserver.py I always get this error concering Flask-bcrypt:

 File "/Users/drubio/Desktop/blackduck_directory/venv/gaenv/flask_bcrypt.py", line 27, in <module>
    raise e
ImportError: No module named bcrypt._bcrypt

Has anyone encountered this problem before? I've found these resources regarding flask-bcrypt here Flask-bcrypt for GAE not working and here How to use py-bcrypt with GAE.

From these resources I've learned that FLask-Bcrypt might not be written as a pure python package which it needs to be for GAE to upload and second there is another alternative called py-bcrypt. However while looking at its github page, it seems to be abandonware so I don't want to waste time with that? Are there any suggestions anyone has out there?

you need to install the bcrypt module, the github link is here:

https://github.com/pyca/bcrypt/

and notice the information , in ubuntu , you need to make sure this has been installed:

sudo apt-get install build-essential libffi-dev python-dev
