Mistakes encountered following the installation of lodash in Angular 2

After adding lodash to my Angular 2 project, I encountered a significant number of errors. To troubleshoot, I created a new project using the CLI: ng new tester, then I added lodash with npm install --save @types/lodash. When I ran ng serve, I received the following error stack:

ERROR in /Users/bradley/Work/test/tester2/node_modules/@types/lodash/index.d.ts (11502,21): ']' expected.
/Users/bradley/Work/test/tester2/node_modules/@types/lodash/index.d.ts (11502,22): ';' expected.
...
(User/bradley/Work/test/tester2/node_modules/@types/lodash/index.d.ts (19507,33): Cannot find name 'object'.

I would appreciate any insights on what might be causing this issue.

Answer №1

Recently I came across a common error that can be fixed by either downgrading the @types/lodash dependency to ts2.0,

"dependencies": {
    "lodash": "^4.17.0",
    "@types/lodash": "ts2.0",
}

or updating your typescript version to 2.2:

{
  "dependencies": {
    "lodash": "^4.17.0",
    "@types/lodash": "^4.14.58",
    "typescript": "^2.2.0",
  }
}

The correct usage would be import * as _ from 'lodash';
