I have a an Angular project (which has multiple projects inside) which I updated to Angular v18.2.12. I managed to update all dependencies but TS doesn't let me build, since 4.0.8 is installed but needs either 5.4.0 ro 5.6.0. When I try to run npm i [email protected] the terminal gets stuck in the process of the install, specifically with this segment of code:
npm WARN Could not resolve dependency:
npm WARN peer typescript@">=2.1.0 || >=2.1.0-dev || >=2.2.0-dev || >=2.3.0-dev || >=2.4.0-dev || >=2.5.0-dev || >=2.6.0-dev || >=2.7.0-dev" from [email protected]
npm WARN node_modules/tslint
npm WARN dev tslint@"~5.7.0" from the root project
[#########.........] - idealTree:trunk: timing idealTree:#root Completed in 421ms
Am I doing something wrong?

Reset to default 0To perform the install without the dependency errors, you can use --legacy-peer-deps argument.
npm i typescript@~5.4.0 --legacy-peer-deps
After installing the correct typescript you have to upgrade tslint to ^6.1.3.
npm i tslint@^6.1.3 --legacy-peer-deps
The legacy peer deps is just to update the package.json with the proper versions, after you do this, there is no need for the --legacy-peer-deps params, npm install should work as it is.
