OS X 安装pyspider

pyspider安装的过程当中，须要安装pycurl。有几个坑

1、首先遇到权限的问题

由于/Library目录是root权限，因此非root用户对该目录的读写常常会遇到权限问题，可是不宜切换成root用户来安装应用，解决办法命令后面加上“--user”，

缘由以下：

Try "python setup.py install --user" You shouldn't use sudo as suggested above for two reasons:

1.You're allowing arbitrary untrusted code off the internet to be run as root

2.Passing the --user flag to python setup.py install will install the package to a user-owned directory.

Your normal non-root user won't be able to access the files installed by sudo pip or sudo python setup.py

2、openssl问题（'openssl/ssl.h' file not found）

输入命令：

export PYCURL_SSL_LIBRARY=openssl
pip install pycurl

问题：'openssl/ssl.h' file not found

解决办法：

brew install openssl

配置环境变量

编辑bash_profile

# openssl
LD_LIBRARY_PATH=/usr/local/Cellar/openssl/1.0.2o_2/lib:"${LD_LIBRARY_PATH}"
CPATH=/usr/local/Cellar/openssl/1.0.2o_2/include:"${CPATH}"
PKG_CONFIG_PATH=/usr/local/Cellar/openssl/1.0.2o_2/lib/pkgconfig:"${PKG_CONFIG_PATH}"
export LD_LIBRARY_PATH CPATH PKG_CONFIG_PATH
export LDFLAGS=-L/usr/local/Cellar/openssl/1.0.2o_2/lib
export CPPFLAGS=-I/usr/local/Cellar/openssl/1.0.2o_2/include

保存后，source， 再次执行一遍下面的命令

pip uninstall pycurl# 卸载包
export PYCURL_SSL_LIBRARY=openssl
pip install pycurl --compile --no-cache-dir# 从新编译安装

OK

3、安装pyspider

pip install pyspider --user
