命令行下查看python和numpy的版本和安装位置:

1、查看python版本

C:\Users\Rnanprince>python -V
Python 3.7.3
C:\Users\Rnanprince>python --version
Python 3.7.3

注意:‘--version'中有两个‘-’

2、查看python安装位置

方法一: 

C:\Users\Rnanprince>python -c "import sys; print(sys.executable)"
D:\Program Files\Anaconda3\python.exe

方法二:

C:\Users\Rnanprince>python -c "import os; print(os.sys.executable)"
D:\Program Files\Anaconda3\python.exe

3、查看包版本

以Scipy为例:

方法一:

C:\Users\Rnanprince>python -c "import scipy; print(scipy.version.version)"
1.2.1

方法二:

C:\Users\Rnanprince>python -c "import scipy; print(scipy.__version__)"
1.2.1

4、查看包的安装路径

C:\Users\Rnanprince>python -c "import scipy; print(scipy.__file__)"
D:\Program Files\Anaconda3\lib\site-packages\scipy\__init__.py
