Heroku: Error: Cannot find module node-gyp

Started getting this error on heroku deployments yesterday (03/23/18) and have no idea why. No package changes or anything relating to node modules. This error gets thrown on yarn install

Any help would be appreciated.

Solution

  • The problem was due to NPM releasing a broken update. Rolled back from 5.8.0 to 5.7.1.

    --EDIT-- To lock an NPM version on Heroku, add the following code to your package.json file. "engines": { "npm": "5.7.1" ...other stuff },
