python - 使用 Pip 安装 Python 库

Question

预先感谢您的帮助!

我正在尝试使用 Pip 1.5.2 安装一组 Python 2.7.5 库。我正在关注directions to install NuPIC on my mac (OS X Mavericks) 。一切都很顺利，直到我运行了这行代码:

sudo pip install --allow-all-external --allow-unverified PIL --allow-unverified psutil -r $NUPIC/external/common/requirements.txt

我收到此错误:

building '_imagingft' extension

#include <freetype/fterrors.h>

         ^

error: command 'cc' failed with exit status 1

这是要求文件 ($NUPIC/external/common/requirements.txt):

#See http://www.pip-installer.org/en/latest/requirements.html for details
asteval==0.9.1
mock==1.0.1
ordereddict==1.1
PIL==1.1.7
psutil==1.0.1
pylint==0.28.0
pytest==2.4.2
pytest-cov==1.6
pytest-xdist==1.8
python-dateutil==2.1
PyYAML==3.10
unittest2==0.5.1
validictory==0.9.1
PyMySQL==0.5
DBUtils==1.1
numpy==1.7.1
tweepy==2.1

它运行了一段时间，所以我认为它成功安装了一些库并在其中一个上崩溃了。有什么想法出了什么问题吗？

这里的“链接”问题Error installing Python Image Library using pip on Mac OS X 10.9回答这个问题(得票最高的答案)。基本上 PIL 不再正确安装 freetype header 。您需要将新位置链接到/usr/include/freetype。
