pycharm与cmd运行导包的区别

1， pycharm 运行会直接把当前运行目录加入到sys.path中
2， cmd运行会出现找不到module的情况，需要sys.path.append('package')加入到sys.path中

Python运行时包的搜索路径如下：

sys.path获取搜索路径顺序

sys.path

获取如下：

['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/lmy666/Library/Python/3.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages']
