RC5 - error "build dev failed: Cannot set property 'fileSystem' of null"

[Tusharbalar]

Hi,
I have this error:
"build dev failed: Cannot set property 'fileSystem' of null "

when I use "ionic serve"

but if I run "ionic build browser", everything is ok.

I've removed all my node_modules and do a fresh "npm install".
I've deleted the ".tmp" & "www" dir too, but the error still displaying.

Please, can you help me? Thanks you,
best regards

@markholland @Quocnamit @Tusharbalar Guys, just switch to @ionic/app-scripts@1.0.0 - this will solve the problem :-) Ps. Read app-scripts upgrade docs, cause many changes after 0.0.46.

[markholland]

Guys, just switch to @ionic/app-scripts@1.0.0 - this will solve the problem :-)

Guess it's time to resolve the reason why we stuck on 0.0.46 then

Thanks @lleevvyy

@dilipchandima Did you add the sw-toolbox dependency?

[carstenbaumhoegger]

I also had this error with RC3 and app-scripts 0.0.43 and it was solved by updating to RC5 with app-scripts 1.0.0.
@dilipchandima don't forget to run npm install after upgrading to app-scripts 1.0.0

[Tusharbalar]

@dilipchandima @Quocnamit you need to install sw-toolbox.

• npm install sw-toolbox

It's solved my problem.

please read this: 2.0.0-rc.5 CHANGELOG

[ebartan]

its work it to me thx guys

[Quocnamit]

Hi,

My old version is 0.0.42. Now It's 1.0.0 👍 . So that I need to update some file name, and update my custom configuration (sass, copy, webpack,...)

Now it works for me

Thanks guys

[jediwarpraptor]

This worked for me, too! Thanks guys.

[danbucholtz]

It seems that this is user error and not app-scripts error so I'm going to close this thread.

Thanks,
Dan

[almgwary]
