Hi guys,

I have installed nexus because of its compelling promise to host maven, npm and pypi repos in the same place.

However I have some issues with the pypi part. I am not sure what I miss here, therefore you're help would be greatly appreciated.

Problem with search:

Running "pip search project_name -i https://user:pass@fqdn/repository/my-python-repo/ -vvv"

I end up with: "HTTPError: 500 Server Error: javax.servlet.ServletException: java.lang.NullPointerException for url: https://fqdn/repository/my_python_repo/"

Problem with install:

Running "pip install flash -i https://user:pass@fqdn/repository/my-python-repo/ -vvv" brings also no success:

...

Could not find a version that satisfies the requirement project_name (from versions: )

Thanks again

Cheers
