Webpack warning: Optional 'weekstart' can't resolve

[cd]

Versions

• vue: 2.5.17
• vue-datetime: 1.0.0-beta.8
• luxon: 1.8.1

Description:

I installed (via npm) vue-datetime and luxon without weekstart, because I don't need it. Unfortunately, when I build my vue project with webpack (using vue-cli), it throws a warning:

WARNING  Compiled with 1 warnings                                                                                                                    
warning  in ./node_modules/vue-datetime/dist/vue-datetime.js
Module not found: Error: Can't resolve 'weekstart' in ...

I think the weekStart function in vue-datetime.js will cause the warning, because it tries to require weekstart in line 153:

try {
  weekstart = require('weekstart');
} catch (e) {
  weekstart = window.weekstart;
}

How can I get rid of the warning? Maybe it is a webpack issue, but maybe this can be solved in a better way?

This is because the weekStart method is called 6 times when the component is created, and one of this weekstart get an empty object value. To solve this problem I do this in my fork

try {
  weekstart = require('weekstart/package.json').version ? require('weekstart') : null
} catch (e) {
  weekstart = window.weekstart
}

I don't know if that solution is the best one. What do you think Mario?

I had the same problem. Fixed installing weekstart.

npm i weekstart

Hope this helps.
