Nodejs 未部署在 heroku 上 - node-pre-gyp install --fallback-to-build

Question

first of all i want to establish, this is my first time experience with heroku. I have tried "git push heroku master" several times with lot of different ways. It always shows the error I mentioned in the subject. None of heroku's troubleshooting helped me.

following is the output after "git push heroku master"

Answer 1

I had exactly the same problem and the solution below helped me. You probably included the node modules in your git repository, and it's better if they are out of git. To remove them from git, try doing:

$ echo 'node_modules' >> .gitignore
$ git rm -r --cached node_modules
$ git commit -am 'ignore node_modules'

Then:

git add .gitignore
git commit -m "ready to deploy"
git push heroku master
