查看python搜索包的路径的实现方法：
python搜索包的路径存储在sys.path下
查看方法：
import sys
sys.path
临时添加python搜索包路径的方法：
方法1：（先进入python）
import sys
sys.path.append(‘路径')
（这种方式仅对当前python有效）
方法2：
export PYTHONPATH=路径
(这种方式对所有的python有效)
永久写入sys.path的方法：
方法1：
在已有的sys.path搜索路径下添加 .pth文件，文件内容格式为：
import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")
方法2：
在home文件夹下的.bash_profile文件中添加下面一行：
export PYTHONPATH=路径
注意，启动不同的python之后sys.path的值是不同的，例如：
启动conda下的python是sys.path的值
