Question

我想设置ENV变量，以保证本地和远程Heroku实例之间的API密钥安全。我按照https://devcenter.heroku.com/articles/heroku-local

中列出的步骤进行操作

当我运行heroku本地时，退出时出现“错误[ERR_UNKNOWN_SIGNAL]：未知信号：null”。任何线索为什么我会得到这个？我的应用程序并不复杂。

Answer 1

这已在@heroku/foreman包中修复。确保您使用的是@heroku/foreman而不是node-foreman。

出口null上的Heroku Local抛出ERR_UNKNOWN_SIGNAL错误
