Failed to load resource: the server responded with a status of 404 (Not Found) - Ionic2

Question

my project is working fine until ytd. I am not sure why, when I “ionic serve” the project, this error keeps prompting.

Ionic Serve Error Message

And I went to check my build folder in WWW, all the files are gone except these.

Build Folder files

I have already tried the below methods but all doesn't work for me:

1. Create a new project and put in my files.
2. npm install
3. npm install @ionic/app-scripts@latest --save-dev
4. npm install -g ionic cordova

Any idea, what I can do to install back my build folder files?

Answer 1

The same problem I had when one of the plugin in "plugin.xml" file had wrong path. Wrong:

<config-file target="app/src/main/res/xml/config.xml" parent="/*">

Good:

<config-file target="res/xml/config.xml" parent="/*">

I had the same problem but solved it by just clearing the browser data/history . NOTE that I'am using v4. beta ionic I hope that helps!
