Question

当我尝试在我的Ubuntu-12 *上运行一些.py文件时（它是通过VirtualBox模拟的）我收到了消息：

raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

在寻找答案之后，我在这里找到了解决这个问题的一些潜在方法：PIL /JPEG Library / Help!，特别是（我想的）这里：https://stackoverflow.com/a/12301138/1522479 ...说下面的地方：

On Ubuntu precise, PIL doesn't find the jpeg library files, even once they are installed. The easiest way to fix this is to make a symlink after you have installed the jpeg dev package. So, I needed an extra step:

for x64 OS

pip uninstall PIL
sudo apt-get install libjpeg8-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib
pip install PIL

然而，当我尝试这个解决方案时，我没有得到理想的结果。这里是日志的结尾（抱歉这么大的一块）：

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.

另一个问题是我没有使用linux（我真的被迫在几个月前开始做它），所以我不知道如何管理这种情况。真的，我需要帮助。附：如果重要 - 在我尝试运行.py文件之前，我已经安装了pygame（成功）。

Answer 1

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

表示您有权限问题，如果您确实要在系统范围内安装PIL，请使用：

sudo pip install PIL

您也可以安装到用户拥有的目录：

sudo pip install --install-option="--prefix=$PREFIX_PATH" PIL

或者，最好安装在virtualenv中，

Answer 2

您可以尝试安装枕头而不是PIL的叉子。我将它用于所有需要PIL的网站。

安装pip install pillow
