MacBook安装yaml
0.缘起：
遇到报错
ImportError: No module named yaml
尝试安装
sudo easy_install pyyaml
一直卡住。。。
————————–分割线——————————-
解决方案：
1.下载yaml
http://pyyaml.org/wiki/PyYAML 已不能访问（2018-07-20）
用这个：
https://pypi.org/project/PyYAML/
我用的MacBook
DOWNLOADS,下载包source 包
2.安装yaml并测试
$ python setup.py install
running install
running build
running build_py

libyaml is not found or a compiler error: forcing --without-libyaml
(if libyaml is installed correctly, you may need to
specify the option --include-dirs or uncomment and
modify the parameter include_dirs in setup.cfg)
running install_lib
creating /Library/Python/2.7/site-packages/yaml
error: could not create '/Library/Python/2.7/site-packages/yaml': Permission denied
遇到如下报错：
a)fatal error: 'yaml.h' file not found,如提示libyaml is not found or a compiler error: forcing --without-libyaml
如果要安装libyaml，需要另外下载libyaml包并执行如下命令进行binding
$ python setup.py --with-libyaml install
b)error: could not create '/Library/Python/2.7/site-packages/yaml': Permission denied
使用如下命令即可：
$ sudo python setup.py install测试yaml 1
$ python setup.py test
running test
running build_py
running build_ext
