Following the answer suggested in the question -
Is it possible to permanently set environment variables?
I was able to set new environment variables permanently with the command -
spawnSync('setx', ['-m', 'MyDownloads', 'H:\\temp\\downloads'])
But now my goal is to append new values to the PATH environment variable.
Is it possible?
Why don't you just get the environment variable and then append to it?
Ie
const {spawnSync} = require("child_process");
const current_value = process.env.PATH;
const new_path_value = current_value.concat(";", "/some/new/path");
var result = spawnSync('setx', ['-m', 'PATH', new_path_value])
// STDOUT
var stdOut = result.stdout.toString();
console.log(stdOut)
// STDERR
var stdErr = result.stderr.toString();
if(stdErr === '') {
console.log('Successfully set environment variable')
} else {
console.log(`ERROR: ${stderr}`)
}
Update "/some/new/path" and run this as admin as the link you provided suggests and it should work.
I don't have rights to modify my registry, and I also would rather not call an OS command such as setx
.
The following adds an additional component to the Windows PATH. I then ran Selenium, which uses the new setting.
// Display current value of PATH
const current_value = process.env.PATH;
console.log("PREV VALUE:")
console.log(current_value)
// Add the additional entry
const addl_entry = String.raw`\my\new\path\component`
process.env["PATH"] = addl_entry + ";" + current_value
// Display the new value
console.log("NEW VALUE:")
console.log(process.env.PATH)
