ubuntu下python包安装位置

方法1

查看当前版本python执行命令路径：

tu@tu-Aspire-A615-51G:~$ which python
/home/tu/local/anaconda3/bin/python

相应的包安装在lib下，所以包路径即在/home/tu/local/anaconda3/lib/pythonX.X/下。

方法2

查看已安装的包：

tu@tu-Aspire-A615-51G:~$ pip list
Package                            Version    
---------------------------------- -----------
absl-py                            0.6.1      
alabaster                          0.7.10     
anaconda-client                    1.6.9      
anaconda-navigator                 1.7.0      
...

任选安装的一个包，查看包的安装路径：

tu@tu-Aspire-A615-51G:~$ python -c "import alabaster;print(alabaster)"
<module 'alabaster' from '/home/tu/local/anaconda3/lib/python3.6/site-packages/alabaster/__init__.py'>

或者

tu@tu-Aspire-A615-51G:~$ pip show alabaster

或者直接查找sys包，原理类似：

>>> import sys
>>> sys.path
