Parcel: Unterminated regular expression (sourcemap)

[Nisthar]

🐛 bug report

I am trying to compile vue components using parcel. The build is not working correctly. I am getting the error mentioned below.

🎛 Configuration (.babelrc, package.json, cli command)

no configs

🤔 Expected Behavior

Build without any errors

😯 Current Behavior

Getting the following error

Could not load existing sourcemap of "../node_modules/vue-runtime-helpers/dist/inject-style/browser.js".
×  \node_modules\vue-runtime-helpers\dist\inject-style\browser.js:28:86: Unterminated regular expression (28:86)

> 28 |       code += '\n + btoa(unescape(encodeURIComponent(JSON.stringify(css.map)))) + ' */';
     |                                                                                      ^

💁 Possible Solution

If i comment the code causing the error, it works without any problems. But it affects the source maps.

This is a known issue, duplicate of https://github.com/parcel-bundler/parcel/issues/2408 (there's even a PR open to solve this: #2427)

@mischnic Is there a solution for this yet?

Is there a solution for this yet?

That PR will solve this, I don't know of any workarounds apart from the one you mentioned already (apart maybe from disabling source maps completely with --no-source-maps).

@mischnic Thanks. It works without source maps. Hope you will fix the source map issues soon.

Is there any news on this? The same problem happens when using paper.js
