安装枕头时出错（Django）

Question

I'm having trouble getting Pillow to install. Here's the full traceback:

The error seems to be 'Permission denied' when attempting to create the folder; though I cannot understand why...

My machine is running Mac OSX, and I'm using Terminal to run the commands for this Django project.

Answer 1

Because the normal user doesn't have permission to install packages globally. Either run with sudo , or - much better - use a virtualenv and install your packages in there.

Answer 2

There're several questions regarding this problem, I'd suggest to take a look at these:

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

I prefer the second one but it also depends on your project/app structure
