Thanks in advance,

Fails how?

What does the pip output look like?

What does your pip configuration look like?

You'll need to supply some information before anyone can help you.

Rich

When i said pip install <my package>, it looks through in https://pypi.python.org/simple not in http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-hosted/ .

Here is the pip output:

The .pypirc file configuration is for publishing.

See "Global pip.conf file with a repository group" section here for configuration needed to have pip retrieve packages through Nexus:

Thanks Rich. I tried creating pip.conf under ~/.pip/pip.conf.I am using pip version-9.0.1 and python image-2.7.10

http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/ --pypi group repo

http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-hosted/ -- pypi hosted repo

Here is the config of pip.conf

[global]

index = http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/

index-url = http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-hosted/

This is what i get now

HTTP error 404 while getting http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/

HTTPError: 404 Client Error: Not Found for url: http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/

am i doing something wrong?Let me know.

[Rich Seddon]

As per the instructions in the book, you will need this in the pip.conf file:

[global]

index =  http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/pypi

index-url =  http://nexus-test.dev.iad.oshift.iacp.io/repository/pypi-all/simple

Thank you so much Rich.. It worked like a charm. Here is the command i used: 

pip install <package-name> --trusted-host nexus-test.dev.iad.oshift.iacp.io

Thanks,

Kalai

[Max Hellwig]

You can also add the trusted-host setting to your pip configuration file under global:

trusted-host=nexus-test.dev.iad.oshift.iacp.io

Hello,

I've created a PYPI hosted repository, a PYPI proxy (for https://pypi.python.org), and a repository group containing both.

The hosted repository is named PYPI, the proxy is PYPI-Official, and the group is PYPI-All.

I have two problems when I create ~/.pip/pip.conf with contents:

[global]

index = https://user:long pass wo...@nexus.example.com/repository/PYPI-All/pypi

index-url = https://user:long pass wo...@nexus.example.com/repository/PYPI-All/simple

trusted-host = nexus-repository.example.com

The first is that I'm unable to create virtual environments:

% virtualenv -p python3 venv

Running virtualenv with interpreter /usr/local/bin/python3

Using base prefix '/usr/local/Cellar/python/3.6.4_3/Frameworks/Python.framework/Versions/3.6'

New python executable in /Users/username/venv/bin/python3.6

Not overwriting existing python script /Users/username/venv/bin/python (you must use /Users/username/deleteme/venv/bin/python3.6)

Installing setuptools, pip, wheel...

  Complete output from command /Users/username/venv/bin/python3.6 - setuptools pip wheel:

The second is if I remove ~/.pip/pip.conf and instead create venv/pip.conf with the same contents with a virtualenv in place:

(venv) % pip search six

User for nexus.example.com: user

Password:

(venv) %  pip install six

Collecting six

User for nexus.example.com: user

Password:

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

No matching distribution found for six

So not only is it not using the proxy, it's also ignoring the credentials.

Any advice would be very much appreciated, thanks!
