Question

我正在尝试使用requirements.txt在远程服务器上安装远程环境。

所以首先我去了服务器

去了virtualenv

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Server和Windos机器上有Python27。

这是我的Windows 8输出：

  Using cached Cap1xxx-0.1.3.tar.gz

Collecting and everything is fine

然后有一个追溯：

我不明白这个追溯以及如何处理这个......

也许是因为在开始时我尝试使用从服务器获取的文件而不是在vertualenv中安装依赖项。并且一些跟踪保留在缓存中，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它？</ p>

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），我试图在Windows上安装它。

我应该以某种方式清理/ tmp或缓存......？

Answer 1

在你的情况下，有些软件包在Windows中无法编译。在Raspberry Pi中创建一个virtualenv，在那里安装所有软件包。然后从Raspberry Pi＆amp; amp;中复制site-packages文件夹。将它粘贴在Windows上的Site-Packages目录中。这应该可以。

Answer 2

我可以看到你的情况很简单。您已经实现了一些无法在Windows机器上运行的软件包，例如RpiGpio。因此，只需将它们从您的需求清单中删除即可完成。

使用pip安装requirements.txt
