I am trying to use parcel for the first time. I installed it to my project using the npm install parcel command. Then I tried to start the development server by running the command npx parcel src/index.html and nothing happens. I do not get an error. I allowed the connection when the firewall prompt came up. Does anyone know how to fix this issue?

Result when running npx parcel command

  • What version of `parcel` are you using? I just tried with version `2.2.1` and worked fine. – Christian Tapia Jan 18 '22 at 22:06

    Thanks for replying. I am using v2.2.1. – Deepak Joy Jose Jan 18 '22 at 22:15
  • I have the exakt same problem. Parcel version 1 works, not version 2, regardless of miner version. 2.0.1 doesn't work, 2.2.1 doesn't work. Perhaps a sub-dependency is the root cause? I get no errors and no output, nothing happens. Existing Parcel 2 projects work, but not new once. I will test to run npm install in working projects to see if they fail. – Dick Larsson Jan 23 '22 at 12:12

According to Devon Govett, the creator of parcel, this issue is related to an upgrade of napi-rs in the @parcel/source-map package, which was released sometime after Parcel 2.2.1. For now, they have reverted this upgrade and published @parcel/source-map v2.0.2.

Once I read about this update, I uninstalled parcel, deleted my .parcel-cache folder, and reinstalled parcel. Now the npx parcel src/index.html command works for me.

Try changing the parcel in devDependencies to "latest". I did this when I had an issue using version 2.6.0 and it worked fine.

  • Yes. The issue was with an update parcel had released a few days before I installed parcel from npm. The issue was fixed a few weeks later. Thanks for the input David. – Deepak Joy Jose Aug 25 '22 at 16:51
