"components/formio/formio.component" does not exist in the hypothetical file system!

[Jefreesujit]

Hi, I m trying to setup angular-formio code in my local machine. I just cloned the repo and ran npm run build command. But the build is failing with the following error:

"components/formio/formio.component" does not exist in the hypothetical file system!

This is the complete build log:

Can someone help me set up angular-formio in local? Thanks in advance

Hello Jefree,
Try adding or changing the allowRealFiles status to true and see if you can build.

[Jefreesujit]

@wag110894 The value is already set to true, still build is failing.

Are you using symlinks? If so then that may cause this problem. Regardless, this is a build/environment issue and not a Form.io problem.

[Jefreesujit]

@travist Hi, I didnt use any symlinks. I actually pulled the code and tried building it in local. Yeah, i too found it as a build issue, gulp task was not signaling complete on async actions for fesm and umd builds. based on this answer, I added the done() callback to the failing gulp tasks to get me unblocked.

Just wanted to check if this is just for me, or for others too. I m using a Windows 10 machine, could that be a reason? However, since angular-formio uses gulp 4.x, it is recommended to signal completion for async tasks.

If you made a change to get this working, then do you mind submitting your changes as a pull request so that the community can benefit from this change?

[Jefreesujit]

@travist sure, It may not be a recommended solution, would love to share. I will try to send one by EOD today.

using gulp-better-rollup instead of gulp-rollup fixed the build for me

[Jefreesujit]

@travist, @wag110894 I have updated the pull request based on @ASmeha suggestion. Kindly take a look.

#302

[Jefreesujit]

Closing this issue as the changes were merged as part of #302

[jbarrus]

@travist it looks like this change is what broke the UMD bundles in #392
