I have some env vars set-up in my .bashrc but when I'm running Vimspector, those variables are not set-up. I want to export the env var when staring Vimspector, but I haven't managed to figure out how.

There is a relevant (almost same) question here, but the answer is (probably) "expired", meaning that the links provided do not show that they were supposed to show, probably because the linked scripts have changed.

So, can anyone explain how to export an environment variable to Vimspector?

In the configuration section of the .vimspector.json that you use to define the debugging parameters of the VimSpector session there is a env section that you can use for that.


    "configurations": {
        "grr": {
            "default": false,
            "adapter": "debugpy",
            "breakpoints": {
                "exception": {
                    "raised": "N",
                    "uncaught": "Y"
            "configuration": {
                "type": "python",
                "request": "launch",
                "cwd": ".",
                "python": "python.exe",
                "stopOnEntry": true,
                "console": "externalTerminal",
                "justMyCode": true,
                "debugOptions": [],

                "program": "grr.py",
                "args": ["--debug"],
                "env": { "foo" : "bar" }
