配置pip以从pypi.python.org获取丢失的软件包

Question

我有本地pypi服务器。

然后在

root@localhost$ cat .pip/pip.conf
[global]
index-url = http://localhost/simple
trusted-host=localhost

我的pypi服务器具有paste=2.0.2但是其中一个应用程序需要paste=2.0.3 。 当我签入https://pypi.python.org/simple/paste/它具有此版本。

当我运行pip install -r requirements.txt时，出现以下错误。

Collecting paste==2.0.3 (from -r requirements.txt (line 22))

You are using pip version 9.0.0, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我如何配置pip.conf ，所以当local pypi上没有带编号的特定软件包时，它将搜索pypi.python.org ？

Answer 1

你需要设置

[global]
extra-index-url =  https://pypi.python.org

根据文档在〜/ .pip / pip.conf文件中

此外，您可以使用以下参数启动pypi服务器

  --fallback-url FALLBACK_URL
    for packages not found in the local index, this URL will be used to
    redirect to (default: http://pypi.python.org/simple)
