Python 3 linter does not work (pylint, flake8)

[aliev]

Environment data

VS Code version: 1.19.1
Python Extension version: 0.9.1
Python Version: 3.6.3
OS and version: OS X 10.11.6

Actual behavior

PyLint and Flake8 does not work. I cannot see any errors / warnings in my code even if there are syntax errors

Expected behavior

Should show errors / warnings

Steps to reproduce:

• mkdir -p Project/python
• mkdir -p Project/javascript
• touch Project/python/main.py
• virtualenv -ppython3 Project/python/.env
• source Project/python/.env/bin/activate
• pip install pylint flake8
• touch Project/Project.code-workspace
• code Project/Project.code-workspace

{
	"folders": [
		{
			"path": "python"
		},
		{
			"path": "javascript"
		}
	],
}

• code main.py

import pylint
def name():
    pass

• flake8 main.py

main.py:1:1: F401 'pylint' imported but unused
main.py:2:1: E302 expected 2 blank lines, found 0
main.py:3:9: W292 no newline at end of file

• open Project/Project.code-workspace
• Open python/main.py file
• make any syntax errors in main.py file
• nothing happening

P.S. It works very well without virtual environment
P.P.S. Worked before python virtual environment of the python2.7, now it does not work as well

[DonJayamanne]

The solution is in #435
I'm closing this issue as it is a duplicate.

[aliev]

@DonJayamanne ah great thank you! would be great to add the solution

"python.envFile": "${workspaceFolder}/.envFile"

to FAQ or document that.

[DonJayamanne]

That's a temporary solution, the Jan release will fix this so users wouldn't have to do anything.
