如何为特定的python版本安装软件包

Question

I have two versions of python (3 and 2) and Python 2 is the default one, I want to install a specific package only for Python 3,

I am using windows 7

whenever i use pip install, it is installing python 2 package

How to specify which python version for pio install

Answer 1

python -m pip install package

python3 -m pip install package

This is how you would do it using pip for v2 and v4 respectively.

Answer 2

On windows you can use the following commands in command line:

# For Python 2
pip2 install package_name
# For Python 3
pip3 install package_name

Alternate way:

# For Python 2
py -2 -m pip install package_name
# For Python 3
py -3 -m pip install package_name
