Parcel issues on npm run build.

[aminecmi]

Hello,

I'm trying to install selfoss from scratch. I'm up-to-date with the master branch, and I keep having an issue with parcel.

Here is the error message I keep having.

> @ build /var/www/amine/selfoss/assets
> parcel build index.html opml.html hashpassword.html --dist-dir ../public/ --public-url ./

npm ERR! code ELIFECYCLE

I tried downgrading my npm version from 18 to 16, and then 14, but that didn't work.

Any idea on how to solve this ?

On the latest version of npm, the build fails a little later.

🚨 Build failed.

I have seen some serialization issues when there was assets/.parcel-cache from a different Node version (probably a bug in Parcel). Try deleting the directory.

The latter is caused by source-map package not being compatible with latest Node.js, it is possible to work around it with parcel-bundler/parcel#8005 (comment).

Thanks for this.

Everything works now !

143eef5 bumps the terser that bumps the source-map so hopefully that fixes the second issue.
