Using nexus 3 I configured a proxy python repository using "https://pypi.org" as remote storage. The url of the repository is "http://localhost:8081/repository/pypi/".
Then i used pip to install packages using nexus repository, in $HOME/.config/pip/pip.conf I have the following configurations:
[global]
index = http://localhost:8081/repository/pypi/pypi
index-url = http://localhost:8081/repository/pypi/stable
trusted-host = localhost
Now when I run pip search pexpect it works fine :
User for localhost:8081: someuser
Password:
pexpect (4.7.0) - Pexpect allows easy control of interactive console applications.
pexpect-serial (0.0.4) - pexpect with pyseriat
...
But when I run pip install pexpect I get the following error :
Collecting pexpect
User for localhost:8081: someuser
Password:
Could not find a version that satisfies the requirement pexpect (from versions: )
No matching distribution found for pexpect
Do I need extras configurations in pip.conf or inside my nexus repository ?

To download packages from Nexus instead of Pypi , we need to config pip. ini , most of the time, its not only speed up build processes by caching commonly used dependencies but also help ensuring reproducible builds, since one only depends on their Nexus availability and not the public repositories.
Solution 1: Just update pip You just need to update pip and your error will be resolve. Just follow this command. If you are windows users Then run this command. And then also upgrade setuptools after doing the above.
Description. python-nexus provides simple nexus file-format reading/writing tools, and a small collection of nexus manipulation scripts. Note: Due to a name clash with another python package, this package must be installed as pip install python-nexus but imported as import nexus .
The Sonatype Work directory sonatype-work is created as a sibling to the nexus application directory, and the location of this directory can be configured via the nexus. properties file which is described in Configuration Directory. This directory contains a log of all IP addresses accessing the repository manager.
You should change this:
[global]
index = http://localhost:8081/repository/pypi/pypi
index-url = http://localhost:8081/repository/pypi/stable
trusted-host = localhost
to this (swapping stable for simple):
[global]
index = http://localhost:8081/repository/pypi/pypi
index-url = http://localhost:8081/repository/pypi/simple
trusted-host = localhost
As an alternative, you can install the packages without modifying the config:
If you Nexus PyPi repository is http://localhost:8081/repository/pypi/:
# To install, mind trailing /simple
pip install -i http://localhost:8081/repository/pypi/simple pexpect
# To search, mind trailing /pypi
pip search -i http://localhost:8081/repository/pypi/pypi pexpect
