Javascript heroku日志sh:1:并发：未找到

我可以在本地主机上运行该应用程序，但它在heroku中崩溃。在heroku中启动应用程序时，我似乎遇到了并发包问题。我同时使用了

npmi-S

，但它是在依赖于开发人员的情况下下载的。Heroku中是否有某种类型的设置需要更改以同时使用

尝试此命令

检查初始化对象时是否使用相同的软件包。您可以初始化一个对象，即使它没有安装在依赖项中，也不必使用它。我初始化节点mailer没有使用它，它也没有安装在依赖项中，所有的东西都只在本地运行良好。

apt-get install nodejs-legacy
npm install -g tsc
npm install -g concurrently
npm install -g typescript
