Question

我正在尝试使用Django 1.4.1上的PIL上传和调整图像大小。

我试过这个：https://stackoverflow.com/a/10109941/356875

但没有改变。

我使用virtualenv，当我pip install -I PIL时，我收到此错误：

running install_lib

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

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

所以我必须sudo pip install -I PIL哪个有效并且给我这个：

我做错了什么？

（PS：完全相同的配置在我的远程主机linux服务器上正常工作）

您的activate / workon脚本可能存在问题。尝试传递virtualenv的pip绝对路径，例如：

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

为了检查你的virtualenv中是否安装了PIL，请执行：

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

如果没有错误，则表示已正确安装。

也许您的问题与此相同：System PIP instead of virtualenv PIP by default?

Linux Mint 14＆amp; python PIL给出<decoder jpeg =“”not =“”available =“”> error </decoder>
