Question

我正在尝试在virtualenv中安装PIL，但失败了。我创建了一个全新的virtualenv并做了pip install PIL并获得了以下

这里出了什么问题？如何成功在virtualenv中安装PIL？

Answer 1

使用PIP在Windows上安装PIL会给我带来问题，但使用easy_install可以正常工作。

“c：\ VirtualENV \ easy_install PIL”

Answer 2

PIL是一个库，它有一些用C语言编写的部分，需要Microsoft Visual C ++来编译和构建一个完整的包。从错误消息，它找不到Microsoft Visual C ++的路径。

如果您想从源代码安装（通过PIP），您可以按照this blog

中的说明进行操作

在virtualenv中使用PIL的一种更简单的方法是将预编译的二进制文件从PythonWare安装到Python site-package目录。

然后使用选项virtualenv --system-site-packages ENV重新创建virtualenv 您的virtualenv将从全局站点包继承包。

由于Warning和ValueError，无法在Windows中的virtualenv中安装PIL
