Receiving the the following error – Error from chokidar (T:\Git\PMISG-IntradayUI\node_modules\igniteui-angular-core\ES5): Error: UNKNOWN: unknown error, watch

Hi,

I have recently moved to a virtual(VDI) Windows 10 environment and now I’m receiving the following error when in run my Angular 7 Igniteui application – Error from chokidar (T:\Git\PMISG-IntradayUI\node_modules\igniteui-angular-core\ES5): Error: UNKNOWN: unknown error, watch

Thanks in advance,

JK

Hello,

After an investigation, I determined that it is highly possible this error to not be related with Ignite UI for Angular product in particular. This can be easily determined if you remove the ignuteui-angular package from your application and check what is the behavior and whether you are getting the same exception.

In regards to the chokidar , it uses Nodejs core module fs to watch file system directories. More details could be found here. According to this discussion, it is only intended for backend development, so it would cause errors when you used it in frontend.

Additionally, in this thread, a suggested solution is to try creating an angular app in the C drive. Also, you could try reinstalling Angular CLI after clearing npm cache:

npm cache clean –force

npm install -g @angular/cli@latest

In case that the exception disappears when igniteui-angular is removed can you please add a small isolated sample that demonstrates the issue, so we could investigate this further.

Let me know if I may be of any further assistance.

Thanks for the quick reply.  I moved the development of my app to the C drive and everything is working fine now.
