I accidentally upgraded the dependencies of my project. After that, when I ran the command to start the project, I kept getting an error:

/node_modules/.pnpm/vue-tsc@2.1.10_typescript@5.7.2/node_modules/vue-tsc/index.js:34
            throw err;
            ^
Search string not found: "/supportedTSExtensions =.*(?=;)/"
Node.js v22.11.0

To solve this problem temporarily, I had to downgrade the versions. Specifically, I downgraded vue-tsc to version 2.0.29 and typescript to version 5.6.2.

Here is the updated part of the package.json after the downgrade:

{
  "scripts": {
    "build": "vue-tsc -b && vite build"
  },
  "devDependencies": {
    "vue-tsc": "2.0.29",
    "typescript": "5.6.2",
    "vite": "^5.4.10",
    "@vitejs/plugin-vue": "^5.1.4"
  }
}

This downgrade successfully fixed the issue. It seems that the problem is caused by the incompatibility between vue-tsc@2.1.10 and TypeScript 5.7.x.
