No module named bcrypt : DLL load failed

Question

I am trying to install pysftp on windows as my odoo server is on windows and I used pysftp in my module.

First of all, it gives me an error No module named pysftp. I installed it using pip install pysftp then system gives me same error for different dependencies like paramiko,payn1,cryptography etc. But at last, it gives me an error No module named bcrypt so I tried to install it using pip and it installed successfully. But when I run application it's giving me following error.

Traceback (most recent call last):

 ImportError: DLL load failed: The specified module could not be found.

My pip version is 9.0.1 and python version is 3.5.4

Answer 1

It seems that you have not used proper python version with odoo10 and gets package errors. Check the documentation of odoo10 for correct python version. Use python 2.7.9 for windows to run odoo 10 as mentioned in documentation.

For installing python 2.7.9 packages, use pip command. For installing python3 packages, use pip3 command.

One more thing for the pysftp package. You may get these errors because of the pysftp package is not supported on python 3.5 version. Check pysftp documentation for supported python versions.

I hope this will help you!

Just use this commond in your python/venv: pip install bcrypt
