Topic: File to import not found or unreadable: core/bootstrap/functions.

ADS@Aareon pro asked 5 years ago

We are upgrading to version 7.4.0 and i am getting the following error on ng serve.

File to import not found or unreadable: core/bootstrap/functions. in /Users/.../.../.../node_modules/ng-uikit-pro-standard/assets/scss/mdb.scss (line 31, column 1)

If i look in node_modules/ng-uikit-pro-standard/assets/scss/ folder, the core folder is missing. We are using the git method on this url:


Did many reinstalls, but the core folder just is not copied for some reason.

How can we fix this?

After a fun day of investigating this issue, i managed to get it running bij reverting to an old version of node/npn.

Now on node v8.15.0 npn v6.4.1

A bit of a hack/workaround, but it works for now.

@MDB Team: might want to look into this.Not sure if the problem is node/npm or the MDB package

Yes, the workaround provided by the Crounini should work too.

Yes, you can also:

  • Removed the node_modules directory
  • Downgraded your npm to 6.4.1 version
  • Run npm install
  • Updated your npm to last npm version (6.8.0) sudo npm -g update npm or a command like that...
  • Everything should work correctly...

I solved it through a workaround:

I downloaded the project from gthub and copy "core" folder (ng-uikit-pro-standard-master\assets\scss\core) in node_modules folder of my project (\node_modules\ng-uikit-pro-standard\assets\scss).

Actually I'm using npm 6.8.0

I deleted my whole node_modules folder and ran npm install then npm install typescript@">=3.1.1 <3.3.0" and it works for me now.

Angular CLI: 7.0.4
Node: 10.15.1

Hello, The problem seems to appear when we are using the npm install command with the 6.8.0 npm version. With npm 6.4.1, everything seems to work properly.

I also faced this issue with clean install of 7.4.0 The problem is core folder is missing from that location. I fixed it by placing core folder there from older version 7.3.0.
