Pylint is a Python code analysis tool that analyzes errors in Python code and looks for code that does not meet code style standards and has potential problems.

Pylint is a Python tool that provides more functions than normal code analysis tools, such as checking the length of a line of code, whether the variable name conforms to the naming standard, whether a declared interface is actually implemented, and so on.

Vscode is installed on unbuntu18 to try to write a test learning python. The installation of vscode is simple, and the relevant plug-in configuration of python can also be searched for installation directly. But every time it runs, it always prompts "Linter pylint is not installed", as follows:

But when I install it, it's always prompted that I can't install it.

I have confirmed that my python version, environment variables and pip settings are all correct, and always prompt

"ImportError: No module named setuptools (installation module error)"

Later, I found out the reason: this is a mistake often encountered by beginners. Don't worry, this is because Python in Windows does not install the setuptools module by default, which is also a third-party module.

Solve the problem as follows

Pip3 install setuptools

After this module is installed, you can continue to install Pylint
