我正在尝试安装 Channels 以便将其与 Django 一起使用，并且我想使用 docker（基于 linux）中的 .whl 文件进行此安装。我使用 pip wheel channels 获得了我的 .whl 文件，但是当我尝试安装它们时，它会尝试寻找 Twisted，即使它已经安装。
注意：如果我从我的轮文件中取出 Twisted-myversion.whl，pip 能够正确安装它并且一切正常。该错误仅在 pip 尝试使用 Twisted.whl 文件时发生。我 100% 认为我使用的 whl 文件版本是正确的，因为它与我在不使用 whl 的情况下安装软件包时获得的 pip freeze 输出一致。
警告：我要发布很多信息，我不知道这是否是在 StackOverflow 上提问的正确方式，但我认为向您提供我所拥有的所有信息是一个很好的开始。< /strong>
我尝试使用verbose进行安装，以下是我认为可能有趣的信息：
Processing ./bin/wheels/Twisted-21.2.0-py3-none-any.whl
Added Twisted==21.2.0 from file:///code/bin/wheels/Twisted-21.2.0-py3-none-any.whl to build tracker '/tmp/pip-req-tracker-58_mg5hs'
Removed Twisted==21.2.0 from file:///code/bin/wheels/Twisted-21.2.0-py3-none-any.whl from build tracker '/tmp/pip-req-tracker-58_mg5hs'
-> 这意味着 Twisted 已按预期安装。
