Typescript errors are no more showed in the terminal since vue-tsc 2

[vidal7]

Description

On vue-tsc 2.0.6, console output is empty reporting no typescript errors even if there is an error

Versions

• vue-tsc@2.0.6
• typescript@5.1.6
• vue@2.7.14
• node@20.10.0

Here is the error in vscode

What is happening?

The output of the terminal is empty

What should I expect

Steps to reproduce

• Clone the repo https://github.com/vidal7/volar-issue-vue-tsc-output
• Follow steps in readme.md

I can add that upgrading to typescript version 5.4.2, console now showing something but incomplete.

Same issue, blank lines where the original code was supposed to be. Downgrade to vue-tsc 1.8.27 worked to restore the outputs in the console.

Same issue on vue@3.4.21, typescript@5.1.6. Upgrading TS to 5.4.3 shows empty lines on some errors (some are still fine). Downgrading to 1.8.27 helps.

We are using @volar/typescript v2

@so1ve You're right, I've got confused with dependency versions when switched packages. I'll remove my previous comment. So then I still have an issue with the following versions:

• vue-tsc@2.0.19 (with @volar/typescript@2.2.5)
• vue@2.7.16
• typescript@4.2.4
• node@16.20.2 (the same for 18.17.1/20.12.0)

I tried to debug and found that the following catch swallows an error:

language-tools/packages/tsc/index.ts

Lines 52 to 56 in b80b63a

	} catch (err) {
	if (err === extensionsChangedException) {
	main();
	}
	}

When I run

yarn run vue-tsc --noEmit

The issue it swallows is "createModuleResolutionCache is not defined". It fails in @volar/typescript here: https://github.com/volarjs/volar.js/blob/f17c19f712651acde33cc2171a112e64db0b460e/packages/typescript/lib/node/proxyCreateProgram.ts#L58

The best I found is that vue-tsc tries to call proxyCreateProgram via tsc and passes empty proxy object instead of ts with the required methods. Is this the same issue or a new one?

P.S.: version 1.8.27 works fine for me

Seemed that your typescript version is too old, could you please upgrade to v5 if possible?

[mr-sanders]

@so1ve you're right. This is the problem. It's working for v5.

Probably it makes sense to specify the minimum supported version in package.json or readme. I checked vue-tsc's peerDependencies, and it lists "typescript": "*"

Sure, PR welcome :)
