Ionic Electron Command Failed npm run electron:start

Posted: 6/17/2020 | Categories: Ionic Framework

While testing an Ionic Electron app the other day, I opened a terminal window, navigated to the Ionic project folder, then executed the following command:

npx cap open electron

npm whirled and chunked for a little while, then displayed the following error:

[error] Error: Command failed: npm run electron:start

npm ERR! errno 1

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

This error surprised me, because I assumed the Electron project was configured correctly, but apparently not. I fixed this by executing the following commands In the terminal window:

cd electron
npm install
cd ..
npx cap open electron

The Electron app opened as expected. I'm not sure how the project got into this state, but fortunately it's a quick and easy fix.
