Environment data

• VS Code version: 1.47.1
• Extension version (available under the Extensions sidebar): 2020.6.91350
• OS and version: Ubuntu 19.10 - Linux x64 5.3.0-62-generic snap
• Python version (& distribution if applicable, e.g. Anaconda): python3
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• Value of the python.languageServer setting: I do not see an entry for this in either User or Workspace settings.json
• workspace setting /.vscode/settings.json "python.pythonPath": ".venv/bin/python"

Expected behaviour

Can run source .venv/bin/activate from TERMINAL within vs-code

Actual behaviour

source ends in error

$ source .venv/bin/activate
/bin/sh: 8: source: not found

Steps to reproduce:

Create a folder
Open folder in vs-code
In vs-code terminal run python3 -m venv .venv
Set interpreter path (venv/bin/python)
source .venv/bin/activate - ends in error /bin/sh: 8: source: not found

If I go to the same folder in a terminal outside of vs-code the source .venv/bin/activate command runs successfully without any error.

Logs

These logs are all produced from the python3 -m venv .venv command

@myfree Does source .venv/bin/activate run automatically when you create new terminal? this is expected if you have python.terminal.activateEnvironment set. The reason it fails is probably because you are using an unsupported shell. You can unset python.terminal.activateEnvironment, and manually activate or use bash.

[brentgracey]

thanks for those pointers
Yes; I did have python.terminal.activateEnvironment set. I updated it to false; opened a new Terminal in vs-code; and running python3 -m venv .venv manually does not hit the error.

-> The reason it fails is probably because you are using an unsupported shell.
Is that controlled by the setting "terminal.integrated.automationShell.linux": "" ?
Do you know what values I can set to use a supported shell on Ubuntu?

Are you aware why sourcing automatically can error; where-as it seems that doing it manually works correctly?

Thanks again; follow up questions are mostly just to help me build some understanding of whats going on here.

[karthiknadig]

terminal.integrated.automationShell.linux is a VSCode specific setting, to select shell to use when it needs to run things.

These are the shells that we identify and support. In your case you had selected 'sh' as the default shell for the terminal, which we don't support.

vscode-python/src/client/common/terminal/types.ts

Lines 18 to 30 in 08e4074

	export enum TerminalShellType {
	powershell = 'powershell',
	powershellCore = 'powershellCore',
	commandPrompt = 'commandPrompt',
	gitbash = 'gitbash',
	bash = 'bash',
	zsh = 'zsh',
	ksh = 'ksh',
	fish = 'fish',
	cshell = 'cshell',
	tcshell = 'tshell',
	wsl = 'wsl',
	xonsh = 'xonsh',

You can change the default shell from the command pallet:

'sh' does not have source as an alias. So it fails there. select bash as the default shell for the terminal and it should work.
