Error in page after pack files

[lwenn]

Hi, I use vue-datetime and moment in my project, and I change the attribute locale of the datetime component to value zh-cn, then it's ok when I run in npm run dev. However, I pack all files by npm run build and open the page, there is error like this when click the datetime DOM:

TypeError: Cannot read property 'weekdaysMin' of null
at Object.r [as weekdays] (index.js:formatted:13497)
at s.weekdays (index.js:formatted:13497)
at fs.get (index.js:formatted:13497)

at s.r (index.js:formatted:3480)
at fs.get (index.js:formatted:13497)
at fs.run (index.js:formatted:13497)

Would you help to check what wrong? Thank you.

Can you provide a reproduction? A small project in a repository or something similar...

Hi, I find the version I used is 0.5.2, then I update to 0.6.0, and there is no error using locale, and the same error using moment-locale, and setting locale doesn't work? You could see my reproduction in vue-datetime-sample, it may provide help. You could read the README.md.

locale property was renamed by moment-locale.

About the error, it seems that UglifyJsPlugin is breaking something, I'm trying to found a solution.

I can't use it after build

Hello!
I confirm this error in 0.7.0 version
after "npm run build" command
appears error:

in 0.5.3 everything is clean

Hey guys, any progress?

I'm also trying to locate exact problem.
I can confirm, it is UglifyJsPlugin cousing this only while using locale or moment-locale prop.
So it's clearly connected to moment.js

Did anyone tried to switch moment version or other tricks that may help patching this.?

[art0s]

we waiting component's update ))
#28

[cruonline]

If anyone needs fast and dirty fix, just set keep_fargs to false in uglifyjs options. Works fo me.

*EDITED, set to false, not true...

[shanjixiaboss]

@cruonline sure? but that's default is true, i just used default lang then build all right

[cruonline]

sorry, meant set to false. Sorry for confusion. This happens if you try to do mulitask and are not a cyborg ;-)

[shanjixiaboss]

Oh, no, it's my mistake. I should go to the eye department. /laugh

[mariomka]

Next version is near to be stable but changes are meaningful (see #28) but this error mustn't appear more.
