我在将代码上传到 Heroku 时遇到很多问题

Question

I'm having a lot of trouble deploying my code to Heroku.

I started by going to the Heroku logs. And, the photo is what was there. enter image description here

So, I ran bundle install and got the error

An error occurred while installing pg (1.2.3), and Bundler cannot
continue.
Make sure that `gem install pg -v '1.2.3' --source 'https://rubygems.org/'`
succeeds before bundling.

Eventually, I got that corrected. Just decided to work for some reason. Then, however, I started getting another error when trying to deploy. The error was:

remote: !   Failed to install gems via Bundler.
4:32
remote: !   Push rejected to brownsapp.
remote: 
To https://git.heroku.com/brownsapp.git
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/brownsapp.git'

I then tried git push --force heroku . No dice. Then it came to thinking that it was trying to deploy from the wrong branch. But the main branch is the only branch I have. I checked and made sure. Noticed that the terminal also said

Warning - The same version of this code has already been built:

So, I ran git commit --allow-empty -m "Redeploying" trying to get the app deployed.

No dice. Then I noticed another error saying:

Your bundle only supports platforms ["x86_64-darwin-18"] but your local platform
remote:    is x86_64-linux.`

So, I ran the command bundle lock --add-platform x86_64-linux

And then the error continued to show. I tried deleting the Gemfile.lock file. That didn't help either. I'm at a compete loss. Any help would be appreciated.

Answer 1

I fixed my problem by adding the linux platform to my bundler Gemfile.lock with this commande.

bundle lock --add-platform x86_64-linux

Perhaps you can add it manually. Look for platform in your Gemfile.lock, see the picture here for help https://i.stack.imgur.com/PLpya.png
