无法在生产中使用vue-cli调用npm run build

Question

Expected Behavior

npm run build should create the production dist bundle that I can serve on a given machine

Current Behavior

Despite being able to build locally, whenever I try to run npm run build on an external resource (such as a Digital Ocean VM or Heroku machine), I receive the below error.

Additionally, I have tried running npm rebuild node-sass , updated the material-dashboard.css file to include the underscore: _material-dashboard.css , passing --production in npm install --production , but am having no luck.

nodejs version: v8.11.4 npm version: v5.6.0

I've been trying to solve this for a few hours now but am not having any luck. I don't understand why it works locally but not when on another production machine.

Answer 1

This happens because of a spelling mistake (wrong case) in the import statement of this Vue UI library. The file is named "fullcalendar" while the import is called by "fullCalendar" (notice the capital "C"). When you fix this (make the capital "C" simple in the import statement) it will run the "npm run prod" command successfully. It should be noted that, for me, this did not occur in the windows environment for some reason, but only occurs in the Linux environment.
