安装枕头时出错（Django）

Question

我无法安装Pillow。 这是完整的追溯：

尝试创建文件夹时，错误似乎是“权限被拒绝”。 虽然我不明白为什么...

我的机器正在运行Mac OSX，并且我正在使用Terminal运行此Django项目的命令。

Answer 1

因为普通用户无权全局安装软件包。 使用sudo运行，或者-更好-使用virtualenv并在其中安装软件包。

Answer 2

关于这个问题有几个问题，我建议看一下这些问题：

• 使用virtualenv https://stackoverflow.com/a/19472082/394647
• 使用$HOME https://stackoverflow.com/a/7143496/394647

我更喜欢第二个，但这也取决于您的项目/应用程序结构
