【问题描述】：

我创建了本地 pypi 服务器http://localhost:8080/simple。我上传了我的项目需要的包flask-mongoengine，但是当tox 尝试为pip install 执行nose 的包依赖项时，它尝试从pypi.python.org 下载

    distutils.errors.DistutilsError: Could not find suitable distribution for Requirement.parse('nose')

我的pypi 服务器有nose 包，但不知怎么的，它没有重定向到那个。

尝试了第一个答案，它给出了错误

Traceback (most recent call last):
  File "/var/lib/jenkins/workspace/myproject/.tox/py35/lib/python3.5/site-packages/pip/req/req_install.py", line 82, in __init__
    req = Requirement(req)

    requirement_string[e.loc:e.loc + 8]))
pip._vendor.packaging.requirements.InvalidRequirement: Invalid requirement, parse error at "'[global]'"

ERROR: InvocationError: '/var/lib/jenkins/workspace/myproject/.tox/py35/bin/pip install -i http://localhost:8080 --trusted-host localhost:8080 -r requirements.txt'

【参考方案1】：

指定默认指向本地主机？在$HOME/.pypirc：

[distutils]
index-servers =
    localpypi

[localpypi]
repository: http://localhost:8080/simple
username:<your_localpypi_username>
password:<your_localpypi_passwd>

在requirements.txt 稍远一点，这样的东西可能会代替.pypirc，或者可能需要它来补充：

# requirements.txt
--index-url http://localhost:8080/simple
--trusted-host localhost:8080
flask-mongoengine

对于$HOME/.config/pip/pip.conf：

[global]
timeout = 1
index-url = http://localhost:8080/simple
trusted-host = localhost:8080

是的，这也可能：

https://pypi.python.org/pypi/pypiserver#uploading-packages-remotely

也许：

python setup.py dist upload -r http://localhost:8080/simple

如果 pypi 需要任何依赖项，那么：

PyPI local cache for Jenkins/local builds how to create local own pypi repository index without mirror?

我对所有可以设置 --index-url 和 --extra-index-url 的地方感到困惑，但我的想法是为 pypi 和 pip 设置 index-url？

【讨论】：

仍然是同样的错误，我认为，distutils 将被使用，当您尝试执行 dist upload 时。

谢谢@jmunsch，但我不想上传。我想下载包。对于dist upload，它可以工作，但flask-mongoengine 不是我的包，我的项目依赖于它。

@Nilesh 所以也许--extra-index-url 认为它是一个完全本地的 pypi 服务器？

@Nilesh 更新，所以想了一下，也许试试[global] pip.conf 的东西，我忘了 requirements.txt 和 pip.conf 使用不同的格式。希望对您有所帮助。
