【问题描述】:
我正在尝试在 Django 1.4.1 上使用 PIL 上传图像并调整其大小。
我试过这个:https://stackoverflow.com/a/10109941/356875
但没有任何改变。
我使用virtualenv,当我使用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 工作并给我这个:
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.

但是,当我尝试保存模型时出现此错误:

我做错了什么?
(PS:完全相同的配置在我的远程托管 linux 服务器上运行良好)
编辑:我粘贴了另一个详细的输出谢谢。 http://dpaste.com/867770/
【问题讨论】:
-
我认为你需要使用
-E <your_env_dir>选项安装。 -
我觉得奇怪的是
pip在virtualenv下运行时尝试安装在/usr/lib/python2.7/site-packages中。它不应该安装在/home/chris/.virtualenvs/holistic/lib/pyhon2.7/site-packages中吗?您是否使用了正确的pip来安装PIL?另请参阅documentation。 -
@Rohan 这就是我得到的:
pip install -E holistic PIL Usage: pip install [OPTIONS] PACKAGE_NAMES... no such option: -E@Evert 我总是使用相同的点子(在我完成了workon <my_env>命令之后。所有东西都安装在我的虚拟环境中。PIL 是到目前为止唯一的问题) -
我对 Pillow 有同样的问题(PIL 插入)。说 JPEG 在配置时没问题,但是当我尝试加载 JPEG 时会摔倒。
