ERROR in The Angular Compiler requires TypeScript >=3.1.1 and <3.2.0 but 3.2.1 was found instead

Question

To fix this install the specific typescript version 3.1.6

npm i [email protected] --save-dev --save-exact

In my case below command worked for windows. It will install latest required version between 3.1.1 and 3.2.0. Depending on OS use either double or single quotes

npm install typescript@">=3.1.1 <3.2.0" 

First install your targeted version

npm i [email protected] --save-dev --save-exact

Then before compiling do

   npm i

If you want to use Angular with an unsupported TypeScript version, add this to your tsconfig.json to ignore the warning:

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

npm install typescript@">=3.1.1 <3.3.0" --save-dev --save-exact
rm -rf node_modules
npm install
