Can't pip install from nexus pypi repository

[of...@playstudios-il.com]

Hi,

I've setup a hosted pypi repository on nexus and uploaded a package to the repository.

When I try to "pip install" from that repository, I always get the same error:

unsupported archive format: .1

Could not find a version that satisfies the requirement <my package name> (from versions: )

This is not a permissions issue, and it looks as if the ".1"  in the error is taken from the package version (0.0.1).

When looking in the pypi repository on nexus, I see that the package is stored in the following directory structure:

<package nama>

               |

               | ------> 0.0.1

                               |

                               | ------> <package name>-0.0.1.tar.gz

I can browse as anonymous to the package url on nexus, and I'm also able to install it directly with pip if I put the full url of the package on nexus (e.g.: pip install https://<my nexus url>/<package path on nexus>.tar.gz

I was unable so far to find any solution for this.

Can someone help?

Thanks.

Can you list the exact steps you did to upload to a hosted Pypi repository? Be as specific as possible.

What have you got for the index and index-url values in your pip config?

Hi Peter,

Thanks for your help!

I used setuptools in the setup.py file to upload the package. I created a ".pypirc" file with the following format:

[server-login]

repository: <repository url as indicated in the nexus pypi repository>

username: <user name>

password: <password>

Then, I ran:

setup.py sdist bdist_wheel upload

I also uploaded the file manually to the nexus pypi repo, using the "upload" button, and the result was the same (same directory structure, with the version folder)

I wasn't sure at the begging which url exactly I should put in the extra-index-url field, eventually I clicked the "html view" for the repository, and I put that url:
https://<nexus server dns name>/service/rest/repository/browse/<my pypi repository>/

When browsing to this url I can see the "index of" my package, and below it the versions directory (and underneath it all the files).

Thanks

You need to follow the instructions here for the pip.conf file in order for "pip install" to work:

https://help.sonatype.com/display/NXRM3/PyPI+Repositories#PyPIRepositories-ConfiguringPyPIClientTools

Note that is separate from the .pypirc file.  Has this configuration been done?

I followed the instructions. However, I'm not sure which url exactly should I put in the "index-url" field.

I tried both the "html view" of the repository and the url stated in the repository configuration. both are not working.

[Rich Seddon]

Append "/pypi" and "/simple" to the repository URL:

index = http://localhost:8081/repository/pypi-all/pypi

index-url = http://localhost:8081/repository/pypi-all/simple

Also tried that. Doesn't work...

Hi there, i was having the same problem ,   I added first the proxy urls as the main ones and then i added the extra-index-url =  xxxx.com for the rest of the configurations, that worked for me :) 

[global]

trusted-host: example.com

index-url = https://nexus.example.com/repository/pypi-proxy/pypi

extra-index-url =

        https://nexus.example.com/repository/pypi-proxy/simple

        https://nexus.example.com/repository/pypi-hosted/pypi

        https://nexus.example.com/repository/pypi-hosted/simple
