Install third-party libraries for different python versions in Linux.

Install third-party libraries for different python versions in Linux.

Problem background

Currently, many python versions are installed on linux distributions.

The default version on my machine is python 2.x. When easy_install is used to install third-party libraries, it is also installed in version 2.x by default. In version 3.x, the installed libraries cannot be imported.

Environment: Kubuntu 15.04

Solution

Install the python3-setuptools and easy_install3, and install pip3

Sudo apt-get install python3-setuptools
Sudo easy_install3 pip
Sudo pip3 install pyserial (replace pyserial with the required third-party Library)

Test import again in python3.x environment.

The method is not very simple. This was done only after a long time on the Internet at the prompt of a foreign user. I hope everyone will like it.
