Heroku - unable to install package from github

Question

Trying to deploy my app but Heroku is unable to access the package "express-flash"

Looks like heroku can't load the package with npm if the package is stored in GIThub?

What should I do?

Answer 1

Using npm install If you'd rather use npm install instead of npm ci to create the build environment, you can use the USE_NPM_INSTALL environment variable to let the buildpack know. You can do this by running:

heroku config:set USE_NPM_INSTALL=true

then deploy and voila!
