ERROR in The Angular Compiler requires TypeScript >=3.6.4 and <3.8.0 but 3.8.2 was found instead

Use the version which set ng update command: npm install [email protected]


This means that Angular doesn't support TypeScript 3.8.x yet.

You can bypass this error with angularCompilerOptions.disableTypeScriptVersionCheck: true option in

tsconfig.json

"angularCompilerOptions": {
   ...
   "disableTypeScriptVersionCheck": true,
},
