Error with tinymce

After upgrading node, I now get this error:

src/app/@theme/components/tiny-mce/tiny-mce.component.ts:20:5 - error TS2304: Cannot find name 'tinymce'.

I tried updating my tinymce to the latest version 5.9.2, but then it complained with another error:

Generating browser application bundles (phase: setup)...An unhandled exception occurred: Script file node_modules/tinymce/themes/modern/theme.min.js does not exist.
See "C:\Users\Cameron\AppData\Local\Temp\ng-DrE5FA\angular-errors.log" for further details.
so I put it back to the original version 4.5.7.

Anyone know what is up here?
