运行heroku本地web时无法识别babel-node

I tried deploying Node.js API on Heroku, but shows Application Error.

我试着部署节点。Heroku上的js API，但是显示了应用程序错误。

So, used the "heroku local web" command to test any error..and got an error saying that 'babel-node' is not recognized as an internal or external command, operable program or batch file.

因此，使用“heroku本地web”命令来测试任何错误。并得到一个错误，说'babel-node'不被识别为内部或外部命令、可操作程序或批处理文件。

On the other hand, when I run the command 'npm start' I dont get any error and the server starts running.

另一方面，当我运行“npm start”命令时，我不会得到任何错误，服务器开始运行。

I think the most likely cause is that babel is part of dev dependencies and those are not installed by default via official node.js buildpack. Change NPM_CONFIG_PRODUCTION to false and it should work.

我认为最可能的原因是babel是开发依赖项的一部分，而这些依赖项并不是通过官方节点默认安装的。js buildpack。将NPM_CONFIG_PRODUCTION更改为false，应该可以工作。

You can use command line

您可以使用命令行

heroku config:set NPM_CONFIG_PRODUCTION=false

You can always login into Heroku dyno to check if everything is installed properly

您可以随时登录Heroku dyno，检查一切是否安装正确

heroku run bash
