如何在shell中获取pythonpath？

debian@debian:~$ echo $PYTHONPATH  
/home/qiime/lib/:  
debian@debian:~$ python  
Python 2.7.3 (default,Jan  2 2013,16:53:07)

如何在bash中获取所有pythonpath输出？
为什么echo $ PYTHONPATH不能得到所有的？

环境变量 PYTHONPATH实际上只添加到Python搜索模块的位置列表中。您可以像这样打印终端中的完整列表：

python -c "import sys; print(sys.path)"

或者如果要在UNIX目录列表样式中输出(由:)分隔)可以这样做：

python -c "import sys; print(':'.join(x for x in sys.path if x))"

这将输出如下内容：

/usr/local/lib/python2.7/dist-packages/Feedparser-5.1.3-py2.7.egg:/usr/local/lib/
python2.7/dist-packages/stripogram-1.5-py2.7.egg:/home/qiime/lib:/home/debian:/us
