Unable to add Python3 located in virtualenv

[bobmeliev]

Hi,

Downloaded the latest RED Editor 0.8.7 and in Preferences -> Installed Frameworks trying to add Python3 which is located inside virtualenv folder. Problem is when I choose folder venv/bin RED is detecting two python interpreters 'python' and 'python3' but when I select interpreter and click OK button nothing is happens.

Hi,

Did you selected it by clicking interpreter name or checkbox next to name?

[bobmeliev]

Interpreter name is not clickable, I selected by clicking the checkbox.

Are there any errors in .log file from workspace .metadata folder?

[bobmeliev]

I see NullPointerException.

Thanks for stacktraces.

It looks like there is a problem with creating python files in system tmp directory.
Can you check if you have properly configured tmp directory and you have access to it?
I have reproduced your problem when renamed /tmp to /tmp2.

When "Installed fraemworks" preference page is opened, temporary directory containing python files used by RED should be created there with prefix "RobotTempDir".
