使用 pip 安装 requirements.txt

Question

我正在尝试使用 requirements.txt 在远程服务器上安装远程环境。

所以我先去Server去virtualenv by

source bin/activate 并输入：

pip freeze > requirements.txt 

然后在我的 Windows 机器上运行：

pip2 install -r requirements.txt

我目前在服务器和 Windows 机器上有 Python27。

这是我的 Windows 8 上的输出：

Collecting and everything is fine

然后有一个回溯：

我不明白这个回溯以及如何处理......

可能是因为一开始我尝试使用从服务器获取的文件不在 vertualenv 中安装依赖项。并且一些痕迹保留在缓存中，但是当我清理 pip 的缓存时没有任何变化。

那么这里有什么问题以及如何处理呢？

提前致谢！

编辑一个：

问题是 RPI.gpio 仅适用于 linux 机器（更准确地说是 Raspberry Pi），我正在尝试在 Windows 上安装它。

那么我应该以某种方式清理 /tmp 还是缓存...？

Answer 1

在您的情况下，有些包在 Windows 中无法编译。在 Raspberry Pi 中创建一个 virtualenv，在那里安装所有包。然后从 Raspberry Pi 复制 site-packages 文件夹并将其粘贴到 Windows 上的 Site-Packages 目录中。这应该工作。

Answer 2

据我所知，在您的情况下，有一种简单的方法。你已经实现了一些不能在 Windows 机器上运行的包，比如 RpiGpio。因此，只需将它们从您的需求列表中删除并完成即可。
