问题描述
我正在尝试通过 Heroku 托管我的 React 应用程序（使用 mongodb 后端）。
这是我第一次运行 Heroku，ReactApp 是在 Heroku 实现之前构建的。我的最终目标是一次性托管 MongoDB 后端和 React 前端。
文件通过 Github 托管到 Heroku 我遵循教程并上传了所有内容，但我一次又一次地遇到此错误：
npm ERR! (Insert Dependancy here)valid-url not accessible from @heroku-cli/plugin-buildpacks
通常表现为：
npm ERR! valid-url not accessible from u/heroku-cli/plugin-buildpacks
npm ERR! @heroku/buildpack-registry not accessible from @heroku-cli/plugin-buildpacks
我在这里试过答案：[https://stackoverflow.com/questions/64629076/heroku-heroku-buildpack-registry-not-accessible-from-heroku-cli-plugin-buil][1]
（稍作改动，推出：npm i @heroku/buildpack-registry valid-url 而不是建议的解决方案）但没有奏效。
我尝试删除/重新安装 package-lock.json，删除并重新安装 @heroku-cli/plugin-buildpacks 几次，然后删除并重新安装（使用 npm i ）我的 node_modules 文件夹（和 package.lock ) 多次，但问题仍然存在。
我尝试重新安装它要求的依赖项（valid-url 或 @heroku/buildpack-registry），但没有效果。
我还尝试通过命令行（使用 git push heroku master）部署应用程序并通过 Heroku 网络应用程序部署它，但这些会产生相同的结果。
我已将其缩小为 buildpack 问题，但不确定下一步该去哪里。我注意到 Heroku 支持自定义 buildpacks 存储库（例如用于 create-react-app 等），但我担心这会打开一个全新的蠕虫罐。非常感谢您的帮助！
这是我的 Package.json（错误消息如下。如果您需要更多文件或详细信息，请告诉我）
