I took a project in Angular for maintenance, but it’s in the version of Angular CLI 4.2 My system is with the versions of Node, Typescript and Angular cli in the following versions: Angular CLI: 10.0.6 Node: 12.18.3 Typescript: Version 3.9.7 OS: win32 x64

My project is with the versions:

D:\VSTS\ASMS\ASMS.Angular4.2>ng --version
Your global Angular CLI version (10.0.6) is greater than your local
version (1.3.0). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

While trying to run the project is returning me the following errors:

I have no experience in Angular, so I have no idea how to solve these mistakes.

Does anyone have any idea what I should do?

  • Inside the.json angular there is a "tsConfig" variable, check if it is pointing correctly to your tsconfig.app.json. With this, also check if there is a tsconfig.app.json.

Try deleting the node_modules folder. Then delete the package-lock.json file After that check the typescript version on your machine, not in the project, and leave it with the same suggested version in the package.js file. After that run npm install
