几天来，我一直在努力为 python 安装 matplotlib 库。我有 freetype、XCode、X11 和绑定(bind)，但现在当我尝试安装 matplotlib 时，我收到以下错误:
building 'matplotlib.backends._macosx' extension
gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -arch i386 -arch x86_64 -g -O2
-DNDEBUG -g -O3 -DPY_ARRAY_UNIQUE_SYMBOL=MPL_matplotlib_backends__macosx_ARRAY_API
-DPYCXX_ISO_CPP_LIB=1 -I/Library/Frameworks/Python.framework/Versions/2.7/lib

-o build/temp.macosx-10.6-intel-2.7/src/_macosx.o
In file included from /System/Library/Frameworks/Foundation.framework/Headers/Foundation.h:161,
from /System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12,
from src/_macosx.m:1:
/System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h:16:
error: expected ‘,’ or ‘}’ before ‘__attribute__’
这伴随着一些关于已弃用的 numpy API 的警告，但这些似乎没有引起任何问题。谁能告诉我这里的问题是什么？
郑重声明，我使用的是 gcc-4.2。
请您参考如下方法:
只需编辑/System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h:
sudo nano /System/Library/Frameworks/Foundation.framework/Headers/NSUserNotification.h
将第 16 行从:
NSUserNotificationActivationTypeReplied NS_AVAILABLE(10_9, NA) = 3
到:
NSUserNotificationActivationTypeReplied /* NS_AVAILABLE(10_9, NA) */ = 3
然后重试安装 matplotlib:
sudo pip install matplotlib
这帮我解决了!
