Answer 1

Are you doing "npm install" command before npm start?

Any project you are cloning from git it won't have node_modules(which is having necessary library to run that application).

While "npm install" command, it will download all the required libraries based on your package.json/package-lock.json.

If already you run "npm install", you can fix this issue using below command

npm i npm-cli --save

您需要在本地安装打字稿。

yarn global add typescript
