Node.js 错误：无法在heroku中推送某些引用

我在网上学习如何在Heroku部署的课程。我制作了一个Git存储库，上传并提交了那里的所有文件。然后我键入以下命令：

heroku创建

heroku git:remote-由heroku提供的名称

git-push-heroku-main

在命令3之后，我在cmd中遇到了这个错误：

我是新来Heroku的，所以我无法理解错误是怎么说的。还尝试了使用git-push-heroku-HEAD:master，但遇到了相同的错误

如何解决此问题？

参考本文：

删除根文件夹rm-rf node_modules中的node_modules文件夹，因为heroku将安装所有依赖项，我希望这能起作用

因此，请删除您的节点模块文件夹并再次执行1 2 3

问题在于您的ByScript是否搜索了错误消息？是的，我搜索了此错误并找到了一些关于进行新回购的答案，然后使用相同的方法，尝试“git push heroku HEAD:master”，它为其他人工作并创建了一个分支，然后尝试在其上部署，但出现了相同的错误。没有提到bcrypt，因此我无法挖掘太多。因为它在这里失败>bcrypt@5.0.0安装/tmp/build_88514da7/node_模块/bcrypt remote:>节点预gyp安装--回退以构建远程：远程：sh:1:node pre gyp:权限被拒绝那么我解决此问题的下一步是什么？我卸载并重新安装了bcrypt，但它不起作用您需要此模块吗？它起作用了！！非常感谢您为解决此问题花费的时间和精力。我非常感谢。不客气：）
