发生未处理的异常：安装 ngx-bootstrap 时在 angular 中找不到模块

Question

I want to use ngx-bootstrap so command for it is ng add ngx-bootstrap inside Angular project but I am getting error as:

An unhandled exception occurred: Cannot find module 'C:\Users\Nikhil\Desktop\angular-assignment2\node_modules@yarnpkg\lockfile\index.js'. Please verify that the package.json has a valid "main" entry See "C:\Users\Nikhil\AppData\Local\Temp\ng-oquCOE\angular-errors.log" for further details.

Answer 1

It looks like you are using an invalid command to add the ngx-bootstrap module. The ng add command is only used for Angular CLI commands that involve adding new components, modules, or other Angular structures to your project.

To add an existing module from a third party using yarn :

yarn add ngx-bootstrap

Answer 2

I fixed the problem with an unconventional way. Uninstalling and reinstalling. In my case it was dependency with constants-browserify , and with npm uninstall constants-browserify and then npm install constants-browserify . I solved the error
