npm错误！无法读取未定义的属性'pause‘--Bluemix

Question

我正在尝试将Sails.js应用程序部署到Bluemix，在Bluemix上的工具链的部署阶段(当调用CF PUSH命令时)，我们收到以下错误：

npm错误！无法读取未定义的属性'pause‘

我知道跟踪指向npm-error.log文件，但是，我无法访问它，因为我们无法通过ssh查看文件中的内容，因为应用程序在部署失败后处于“关闭”状态。

同样的代码在8天前通过Cf push {app name}和Bluemix中的一个简单的构建和部署工具链成功部署。

在构建阶段，我可以很好地运行Npm install和npm update。然而，它似乎在部署阶段又这样做了，而且失败了。以下是有关此故障的一些详细信息

到目前为止我试过的东西。-change节点版本-changed npm版本-change依赖项版本要包括^前缀的-removed package.json文件中的所有依赖项和所有依赖项

因此，Sails.js和Nodebuildpack/Bluemix并不能很好地配合。

任何帮助都将不胜感激。谢谢

这也同样发生在我身上。我必须回滚npm的前一个版本: 5.3.0，它现在可以工作了。(顺便说一句: macOS)

只有当我像这样更新我的npm版本时，才会发生错误：

  Update available 5.3.0 → 5.4.1    
   Run npm i -g npm to update

处理它的最好方法是将package.json更新为使用engines，如下所示

"description": "a Sails application",
  "keywords": [],
  "engines": {
    "node": "6.10.1",
    "npm": "5.3.0"
  },

在尝试推送到似乎是由@m-t指定的npm版本的heroku时遇到了这个问题，并且指定了类似上面的版本会使ibm bluemix选择它作为默认节点引擎，而不是使用最新的稳定版本。

，不要忘记总是直接指定节点和npm版本，而不是添加tilde或caret，这只是为了安全。有关tilde and caret的更多信息，请查看https://stackoverflow.com/a/22345808/5836034

因此，我将package.json文件中的sails版本从0.12回滚到0.11，它部署得很好。所以CF推送和最新的sails版本在Bluemix上不能很好地相处。这使用的是Node 8.0和NPM版本^5.0.x
