NodeJS Heroku Deployment error

I am using heroku for my web app. Last few days, I made some changes and made few commits and push to github repos, but not to heroku.

Does this make any problem? Today I tried to push my app to heroku and it spits error message, but I hardly understand what is really a problem.

Here is the error message I got from heroku

-----> Node.js app detected

I got a solution.

Literally, the error message was created because of the lack of fsevents. And I figured out fsevents is the module only that can be installed and run in Mac OS. While my laptop and the heroku server aren't not Mac.

The problem was just created because we are working on the project using github with my coworker. I use ubuntu and he uses Mac. He tried to install ionic in his laptop, and the fsevents came with ionic installation.

After all, I uninstalled ionic, and I could successfully deploy my project to heroku.

The link below helped me to figure out it. Please refer to it if you wanna check it. https://github.com/linnovate/mean/issues/411
