离线python包安装需要连接吗？

Question

虽然我已经脱机下载了一个.whl包，但由于它需要连接到pypi服务器，所以无法脱机安装它。我能做什么?

我已经从PyPI下载了这个软件包，并试图安装它。它真的很奇怪，它想再次连接到网络。我怎么才能解决这个问题？

pip install Keras-2.2.4-py2.py3-none-any.whl --user

我以为它会安装它。但是，下面的消息说，它需要连接到网络。

信息：

Answer 1

尝试指定相对路径或绝对路径。

Linux:

pip install ./Keras-2.2.4-py2.py3-none-any.whl --user

或

pip install /my/path/to/Keras-2.2.4-py2.py3-none-any.whl --user

窗口：

pip install .\Keras-2.2.4-py2.py3-none-any.whl --user

或

pip install C:\my\path\to\Keras-2.2.4-py2.py3-none-any.whl --user
