mac PyCharm添加Python解释器及添加package路径的方法

一、背景

pycharm执行python时，找不到自己安装的package，例如pandas、numpy、scipy、scikit等，在执行时报如下错误importerror: no module named pandas：

traceback (most recent call last):
 file "<input>", line 1, in <module>
 file "/applications/pycharm.app/contents/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 20, in do_import
 module = self._system_import(name, *args, **kwargs)
importerror: no module named pandas

二、问题解决

（1）pycharm添加python interpreter；

（2）给添加的python interpreter添加自已安装的package路径。

1、pycharm添加python interpreter

打开项目设置（pycharm–>preference）

添加interpreter，选中本地python命令所在目录，注意保持1和2中的interpreter一致

2、给添加的python interpreter添加自已安装的package路径

选中刚才添加的interpreter，然后单击底部的”show paths for the selected interpreter”按钮，添加自己安装的package，例如pandas、numpy、scipy、scikit等。

单击底部的”+”号，添加自己安装的package的路径

获取package路径

~ python
python 2.7.10 (default, jul 15 2017, 17:16:57)
[gcc 4.2.1 compatible apple llvm 9.0.0 (clang-900.0.31)] on darwin
type "help", "copyright", "credits" or "license" for more information.
>>> import pandas
>>> print pandas
<module 'pandas' from '/library/python/2.7/site-packages/pandas/__init__.pyc'>

三、补充

查看当前python interpreter执行时加载的package路径

输入命令sys.path
