无法安装 Python package 位于 docker 构建的私有 Nexus 存储库中

Question

I have a private PyPi registry using Nexus. I can publish/install from my host machine without any problems (my personal packages as well as common packages via PyPi nexus proxy). When I try to build a docker image using Dockerfile it allows me to install neither my own packages nor public through the nexus proxy registry (but I still can install public packages from common public registry https://pypi.org/ ).

Dockerfile (part)

RUN pypy3 -m pip install --index-url https://username:password@host/repository/pypi-proxy/ flask
RUN pypy3 -m pip install --index-url https://username:password@host/repository/pypi-private/ my

Error

Collecting flask
  ERROR: Could not find a version that satisfies the requirement flask (from versions: none)
ERROR: No matching distribution found for flask

I saw issues with DNS but I can install from https://pypi.org/ so its not the case.

Answer 1

URLs specified in index-url variable were repository URLs not index URLs. Per https://help.sonatype.com/display/NXRM3/PyPI+Repositories#PyPIRepositories-ConfiguringPyPIClientTools , index URLs seem to end in /simple .
