PIL在我的系统中支持JPEG.

每当我上传时,我的代码都失败了:

File "PIL/Image.py", line 375, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

我该如何解决这个问题？

更新到OS X 10.9后,我的macport出现问题.

我尝试按照本手册https://trac.macports.org/wiki/Migration修复它们.

但是当我安装命令行工具时:

xcode-select --install

我得到消息

无法安装软件,因为软件更新服务器当前无法使用该软件.

同时我成功将我的其他机器更新为OS X 10.9.和安装的命令行工具没有问题,所以它们必须可用.

这里有什么问题？

我想使用pip在Mavericks上安装PIL,但是会出现此错误.

_imagingft.c:73:10: fatal error: 'freetype/fterrors.h' file not found
#include <freetype/fterrors.h>
         ^
1 error generated.
error: command 'cc' failed with exit status 1

我的命令行工具已安装并且是最新的,我发现的每个提示都没有帮助.我该如何编译？

编辑:我刚刚检查过,freetype也已经通过自制软件安装了

我试过谷歌搜索和查找其他人的问题.但是,我仍然找不到在mac os x 10.7.2 Lion上安装PIL(for python 2.6或2.7)的清晰/简单配方.

一直试图用easy_install或pip安装psycopg2,终端卡在xcrun和lipo之间的循环中.

它在xcrun和lipo之间反弹,并永远停留在这个循环中.希望对此有一些见解.

我是OS X Mavericks 10.9,最新版本.

我尝试使用pip/easy_install安装Pillow时遇到一个奇怪的错误:

当我尝试pip install涉及C编译的事情(Pillow特别是)时,我得到一个奇怪的错误:

clang: error: no such file or directory: 'Python.framework/Versions/2.7/Python'

error: command 'clang' failed with exit status 1

我发布了我pip.log的安装.

我认为这个问题是由于OSX 10.10 Yosemite和Homebrew python的结合.你以前经历过这个吗？关于如何解决它的想法？
