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
在寻找答案后，我在这里找到了一些解决此问题的潜在方法:PIL /JPEG Library / Help!特别是(我想)这里:https://stackoverflow.com/a/12301138/1522479 ...以下是哪里说的:
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
但是当我尝试这个解决方案时，我没有得到想要的结果。 这里是日志的结尾(抱歉，这么大一 block ):
PIL 1.1.7 SETUP SUMMARY
--------------------------------------------------------------------
version 1.1.7
platform linux2 2.7.4 (default, Apr 19 2013, 18:28:01)
[GCC 4.7.3]
--------------------------------------------------------------------
*** TKINTER support not available (Tcl/Tk 8.5 libraries needed)
--- JPEG support available
*** ZLIB (PNG/ZIP) support not available
*** FREETYPE2 support not available

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(几个月前我被迫开始使用它)，所以我不知道如何处理这种情况。我需要帮助，真的。 附言如果重要的话——在我尝试运行 .py 文件之前，我已经安装了 pygame(成功)。
请您参考如下方法:
error: could not create '/usr/local/lib/python2.7/dist-packages/PIL': Permission denied
建议你有权限问题，如果你真的想在系统范围内安装PIL，使用:
sudo pip install PIL
您还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，
