I am trying to upload and resize an image using PIL on Django 1.4.1.

I have tried this: https://stackoverflow.com/a/10109941/356875

but nothing changed.

I use virtualenv and when I do pip install -I PIL I get this error:

running install_lib

creating /usr/lib/python2.7/site-packages

error: could not create '/usr/lib/python2.7/site-packages': Permission denied

so I have to sudo pip install -I PIL which works and gives me this:

   PIL 1.1.7 SETUP SUMMARY

    To add a missing option, make sure you have the required
    library, and set the corresponding ROOT variable in the
    setup.py script.

    To check the build, run the selftest.py script.

However when I try to save a model I get this error:

activate您的/workon脚本可能有问题。尝试传递您的 virtualenv 的pip绝对路径，例如：

$ /tmp/myenv/bin/pip install -I PIL

为了检查 PIL 是否安装在您的 virtualenv 中，请执行以下操作：

$ /tmp/myenv/bin/python -c 'import PIL'

如果它没有给您任何错误，则它已正确安装。

也许你的问题和这个一样：默认是 System PIP 而不是 virtualenv PIP？
