const text = "typescript is awesome";
text.replaceAll(/typescript/g, 'ts');

🙁 Actual behavior

Property 'replaceAll' does not exist on type '"typescript is awesome"'. Do you need to change your target library? Try changing the 'lib' compiler option to 'es2021' or later. ts(2550)

But es2021 is not a valid value for lib compiler option in tsconfig.json:

Value is not accepted. Valid values: "ES5", "ES6", "ES2015", "ES2015.Collection", "ES2015.Core", "ES2015.Generator", "ES2015.Iterable", "ES2015.Promise", "ES2015.Proxy", "ES2015.Reflect", "ES2015.Symbol.WellKnown", "ES2015.Symbol", "ES2016", "ES2016.Array.Include", "ES2017", "ES2017.Intl", "ES2017.Object", "ES2017.SharedMemory", "ES2017.String", "ES2017.TypedArrays", "ES2018", "ES2018.AsyncGenerator", "ES2018.AsyncIterable", "ES2018.Intl", "ES2018.Promise", "ES2018.Regexp", "ES2019", "ES2019.Array", "ES2019.Object", "ES2019.String", "ES2019.Symbol", "ES2020", "ES2020.BigInt", "ES2020.Promise", "ES2020.String", "ES2020.Symbol.WellKnown", "ESNext", "ESNext.Array", "ESNext.AsyncIterable", "ESNext.BigInt", "ESNext.Intl", "ESNext.Promise", "ESNext.String", "ESNext.Symbol", "DOM", "DOM.Iterable", "ScriptHost", "WebWorker", "WebWorker.ImportScripts".(1)

🙂 Expected behavior

Is it reproducible when you use TS 4.3.5 in CLI?

What VS Code version are you using and what TS version is used for this workspace (bottom right corner)? Is it workspace version 4.3.5 or some other built-in?

VS Code might yell on lowercase value es2021 (because apparently validation expects uppercase only) but from CLI it would work as expected and replaceAll won't trigger an error in editor.

Thanks, I can use uppercase to fix the problem. But I expect it should be case-insensitive. So I have sent a PR for fix this.

[IllusionMH]

That's awesome!

[nata7che]

having the same issue still. uppercase does not help. any other thoughts on how to solve this?

[cb109]

Changing tsconfig.json lib: ["ES2020"] to lib: ["ES2021"] did indeed solve it for me.

I got the same, because of the file wasn't in the scope of tsconfig (wasn't imported from any of tsconfig.files) It was really confusing, 'til found out.
