Error: Multiple conflicting contents for sourcemap source.

[Lee-Heisenbug]

Hi.
I was trying to use rollup to build a simple vue app. But an error occur every time I changed the style of a component.

I don't know how to fix it. Here is the project file: rollup-issue.zip

Steps to reproduce the behavior

1. Down load the project file.
2. run "npm i".
3. run "npm run watch".
4. make some change to the style block of ./src/app.vue. And the error will show up.

It seems could be fixed by using old version(4.2.0) of rollup-plugin-vue.

Thank you so much for sharing the solution! Hope this will be fixed in future releases.

+1 Ran into this issue as well. I don't get this issue in all circumstances, but files that are nested in imports seem to cause an issue. If I get time I will try to see what could be causing this by comparing the code changes from 4.2.

I will say, it's really hard to not just rollback to older versions. I had zero issues with other builds. It's been a real struggle just to update my dev dependencies and get stuff that has been working for a year to build correctly. Hopefully i get some time to look into this if someone else can't fix this.

Is there an update on this issue? Watching is currently not possible if source maps are enabled.

I have the same problem.This problem occurred when I used the 'router-link' tag to open a routing address with parameters.
