ibm-cloud - cf 推送到 IBM Cloud 失败 : Unable to install node: improper constraint: >=4. 1.0 <5.5.0

Question

我在一个小改动后将应用程序推送到 IBM Cloud(只有一些数据，没有代码或依赖项)。

cat: /VERSION: No such file or directory

该应用程序的旧版本已经在 IBM Cloud 上运行(我认为是从 2019 年 5 月开始)。所以我想知道发生了什么变化，所以它不再工作了。

在 IBM Cloud Foundry 中，必须像这样指定 Node.js 版本

"engines": {
    "node": "12.x"
}

或

"engines": {
    "node": "12.10.x"
}
