为什么Python包不从我的个人PyPI服务器安装?

pip2pi 包裹。但是,当我在客户机服务器上运行“pip install”命令来安装我的包时,我得到了以下错误:

Looking in indexes: https://packages.example.com/simple
Collecting Django==1.8.4 (from -r requirements.txt (line 2))
Collecting django-extensions==1.5.7 (from -r requirements.txt (line 3))
  Could not find a version that satisfies the requirement django-extensions==1.5.7 (from -r requirements.txt (line 3)) (from versions: )
No matching distribution found for django-extensions==1.5.7 (from -r requirements.txt (line 3))

pip install -r requirements.txt

需求文件如下所示:

-i https://packages.example.com/simple
Django==1.8.4
django-extensions==1.5.7
(more packages)

现在,在我的包服务器上,根包目录/var/www/packages具有以下结构:

# /var/www/packages:
├── Django-1.8.4-py2.py3-none-any.whl
├── django_extensions-1.5.7-py2.py3-none-any.whl
├── simple
    ├── django
    │   ├── Django-1.8.4-py2.py3-none-any.whl -> ../../Django-1.8.4-py2.py3-none-any.whl
    │   └── index.html
    ├── django-extensions
    │   ├── django-extensions-1.5.7-py2.py3-none-any.whl -> ../../django_extensions-1.5.7-py2.py3-none-any.whl
    │   └── index.html
    ├── index.html

pip2tgz /var/www/packages/ -r requirements.txt

下面是pip2tgz读取的需求输入文件:

-i https://pypi.org/simple
django==1.8.4
django-extensions=1.5.7
(more packages)

下面是如何在包服务器上设置nginx根目录:

server {
    ...
    root /var/www/packages;
    ...
}

我在客户机服务器上使用python3.5.3和pip19.0.3。

我不知道我做错了什么。pip命令看起来是正确的,但是我想知道pip2pi包是否正确地设置了我的包目录。如果我将客户需求文件中的index参数更改为默认值, https://pypi.org/simple 还原所有程序包,没有错误。

pip install --index-url=https://packages.example.com/simple/ django-extensions
Looking in indexes: https://packages.example.com/simple/
Collecting django-extensions
  Could not find a version that satisfies the requirement django-extensions (from versions: )
No matching distribution found for django-extensions

在检查我的其他包时,我确实看到了一个模式。每当我尝试安装一个程序包时,如果wheel文件名包含下划线(“”)但包目录的规范化名称中包含Python PEP 503中的hypen(“-”),就会出现错误。

例如,django rq失败:

directory: simple/django-rq
file: django_rq-0.9.0-py2.py3-none-any.whl

directory: simple/django-redis-cache
file: django-redis-cache-1.6.5.tar.gz

但另一个不同之处在于前者是一个wheel文件,而后者是一个tgz文件,所以这也可以解释这个差异。我会继续调查的。

根据Ares的建议,我使用verbose选项运行pip install:

pip install --verbose --index-url=https://packages.example.com/simple/ django-rq

错误如下:
