... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser

now when im running ng serve I'm getting a large error msg regarding my @type

example:

ERROR in node_modules/@types/babel__traverse/index.d.ts(68,50): error TS1005: ']' expected.
node_modules/@types/babel__traverse/index.d.ts(68,53): error TS1005: ';' expected.

node_modules/@types/babel__traverse/index.d.ts(68,84): error TS1128: Declaration or st

In my research, I saw that I have to update Typescript to a newer version, when updating to the latest im getting an error saying I must use typescript@">=2.7.2 <2.10" (now im using "typescript": "^2.9.2", ) I ran this command but it still returns the same error. Any idea?

Solution

npm i typescript@2.8.1

solved the issue
