angular error in multi-script loader

Question

I get this error ERROR in multi and have tried to reinstall whats mentioned, degrade, replace with an backup, but i get this error all the time.

This happends when i run ng serve , but it always fails cause of this.

Could anyone help me to get this fixed?

Seems like its calling jquery from node_modules folder, and fails there?

Plus, what does acually this error means ?

Answer 1

Follow these steps:

1. Remove node_modules.
2. Remove package-lock.json or yarn.lock.
3. Install yarn if you don't have it by running the command npm install -g yarn and set it as the default package manager for angular cli by running the command ng set --global packageManager=yarn.
4. Install node_modules using the command yarn install.
5. Check the app by running it using yarn start.

Answer 2

Did you try to import your css files in the general style.css like this:

@import "../node_modules/bootstrap/dist/css/bootstrap.min.css"
@import "../node_modules/flag-icon-css/css/flag-icon.min.css"
@import "../node_modules/ti-icons/css/themify-icons.css"
@import "../node_modules/simple-line-icons/css/simple-line-icons.css"
@import "../node_modules/famfamfam-flags/dist/sprite/famfamfam-flags.min.css"
@import "../node_modules/sweetalert2/dist/sweetalert2.min.css"
@import "../node_modules/ng2-toasty/style-bootstrap.css"
@import "../node_modules/ng2-toasty/style-default.css"
@import "../node_modules/ng2-toasty/style-material.css"
@import "../node_modules/froala-editor/css/froala_editor.pkgd.min.css"
@import "../node_modules/froala-editor/css/froala_style.min.css"
@import "./assets/icon/icofont/css/icofont.css"
@import "./assets/icon/font-awesome/css/font-awesome.min.css"
@import "./assets/css/animate.css" 
@import "./assets/css/custom.css"

And remove them from angular-cli.json.
