ERROR: Service 'app' failed to build

[DocBrown101]

Hello, since a few weeks I can not build the project successfully.

I use for this: yarn run build
Has anything changed in the build process?

This is what the output looks like:
44 problems (40 errors, 4 warnings)
23 errors and 0 warnings potentially fixable with the --fix option.

ERROR Build failed with errors.
error Command failed with exit code 1.

yep, that's because of the web worker plugin that I recently added.
For some reason this doesn't play nicely with vue-cli and/or eslint, which seems to be a known issue.
It usually helps to start the build a second time (without changing any code!) and then it works...
A bit annoying but I couldn't fix it yet.

[DocBrown101]

Since I am building it in a Dockerfile, a second attempt is not so easy. Is there another workaround that can work in a Dockerfile?

Can the web worker plugin be removed temporarily, or are the dependencies too large?

I'll take another look and see if I can somehow fix the error but I can't guarantee it right now

[DocBrown101]

Thanks for the tip!
I have found a nice little workaround.

In the Dockerfile just use these two lines and it will work:

RUN yarn run build; exit 0 RUN yarn run build

In the Dockerfile just use these two lines and it will work:

RUN yarn run build; exit 0 RUN yarn run build

This helped (putting it before the npm installs), but didnt make the Dockerfile run.
I tried to debug the Dockerfile a bit and it looks like we need an npm update and then a vue/cli update.

After adding the vue/cli install:
npm install -g @vue/cli
changing:
npm install
to:
npm install -g [email protected]

and splitting up the npm installs, I got this error:

Step 9/12 : RUN npm run build

sh: 1: vue-cli-service: not found
1 error occurred:

sadly i dont know anything about vue/cli.
