在Heroku上安装bcrypt NPM依赖项时权限被拒绝

如何解决在Heroku上安装bcrypt NPM依赖项时权限被拒绝

我在将应用程序部署到Heorku时遇到问题，我在安装Heroku的同一个git存储库中有一个现有的应用程序（节点js服务器），当我推送Heroku master（git push heroku master）时，我收到了此消息输出：

我剪了一些代码。

我该如何解决？

解决方法

我仅将server.js文件从他的文件夹移动到与Heroku链接的新文件夹，而不复制node_modules文件夹，即可解决此问题，然后我卸载了bcrypt库（在cmd中为“ npm uninstall bcrypt --save”）并安装了bcryptjs库。

现在命令“ git push heroku master”起作用。
