An issue was encountered in the node_modules folder while attempting to access the 'Exclude' name in the lodash collection file. The error message reads: (1783,24): error TS2304: Cannot

When attempting to execute the ng serve command, I encountered an error. See below for more details.

ERROR in node_modules/@types/lodash/common/collection.d.ts(1783,24): error TS2304: Cannot find name 'Exclude'. ... (error list continued) ... src/app/dashboard/dashboard.component.ts(5,21): error TS2307: Cannot find module 'chart.js/src/chart.js'.

Here is a snippet from my package.json file:

{
    "name": "TestApplication",
    "version": "0.0.0",
    "license": "MIT",
    ... (package.json contents omitted for brevity) ...
}

I have already tried the following steps:

  1. Ran npm install
  2. Updated TypeScript version to 2.8
  3. Deleted node_modules and reinstalled using npm install
  4. Ensured all components are up to date

If you have any suggestions or ideas, please feel free to share. Thank you!

Answer №1

After trying various solutions, I finally found the fix...

  1. Navigate to the "\node_modules@types" directory within the project repository.
  2. Execute the command 'npm install lodash'.
  3. Alternatively, you can use 'npm install -D @types/lodash@ts' to revert to a previous version for compatibility.

Answer №2

Here is some helpful information from a GitHub source:

error TS2304: Cannot find name 'Exclude'

It appears that you may need to update your TypeScript version or install a lodash compatible with your TypeScript version like this:

npm i -D @types/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="86eae9e2e7f5eec6f2f5b4a8b3a8b5">[email protected]</a>

Please take note that you mentioned TypeScript 2.8.3 but your package.json file still refers to TypeScript 2.5.3.
