Discord.js 机器人的 Heroku 构建失败

Question

I have been coding a bot using discord.js, visual studio code, and node.js, and I have been trying to host it on Heroku. However, the log in my Heroku project claim that my build is failing, and it is giving the following message when I view the build log of the failure:

-----> Installing dependencies
       Prebuild detected (node_modules already exists)
       Rebuilding any native modules
       
       > @discordjs/opus@0.5.0 install /tmp/build_0229f43f/node_modules/@discordjs/opus
       > node-pre-gyp install --fallback-to-build
       
       sh: 1: node-pre-gyp: Permission denied
       npm ERR! code ELIFECYCLE
       npm ERR! errno 126
       npm ERR! @discordjs/opus@0.5.0 install: `node-pre-gyp install --fallback-to-build`
       npm ERR! Exit status 126
       npm ERR! 
       npm ERR! Failed at the @discordjs/opus@0.5.0 install script.
       npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

       npm ERR!     /tmp/npmcache.q9Do7/_logs/2021-04-19T19_49_08_993Z-debug.log
-----> Build failed

Also, the more recent changes that I have made to my bot, like adding aliases to commands and changing the ping of my announce command, don't apply when I run the bot off of Heroku, but do work when I run the bot locally, and I think that the build failure may be the reason behind this. I may be wrong, but I am still relatively new to coding Discord bots. How can I fix the build failure?

Answer 1

I've been searching for a solution to this problem all day. I finally found it: While hosting your bot on heroku you can use " discord-music-player " instead of @discordjs/opus or opusscript. Tell me if it worked for you!

Answer 2

@discordjs/opus is not allowed on Heroku afaik.

Use opusscript instead if you really need to use music.

But as devs mentioned, @discordjs/opus is much better peformance wise so I recommend searching for another hosting solution if you want the audio streaming functionalities.

Answer 3

Prebuild detected (node_modules already exists) you need to hide your node_modules using .gitignore in your folder project
