在Azure上部署Angular2应用程序时发生节点版本错误

我的package.json看起来像复制下面，但我在部署时出现错误。 我得到错误：没有可用的node.js版本匹配应用程序的版本约束。 谁能请告诉最新的错误。 我给出了这个版本，因为WEBSITE_NODE_DEFAULT_VERSION的值是6.2.1。

PFB快照：

的package.json

Answer 1

作为node.js版本6.2.1您select了在Azure Web应用程序上不可用的版本。 平台上提供的Node.js版本是：

分别为0.6.20,0.8.2,0.8.19,0.8.26,0.8.27,0.8.28,0.10.5,0.10.18,0.10.21,0.10.24,0.10.26,0.10.28,0.10 .29，0.10.31，0.10.32，0.10.40，0.12.0，0.12.2，0.12.3，0.12.6，4.0.0，4.1.0，4.1.2，4.2.1，4.2.2 ，4.2.3,4.2.4,4.3.0,4.3.2,4.4.0,4.4.1,4.4.6,4.4.7,4.5.0,4.6.0,4.6.1,5.0.0,5.1 .1,5.3.0,5.4.0,5.5.0,5.6.0,5.7.0,5.7.1,5.8.0,5.9.1,6.0.0,6.1.0,6.2.2,6.3.0 ，6.5.0,6.6.0,6.7.0,6.9.0。

请尝试使用6.2.2 ，或者您可以尝试select以上可用版本之一。

另外，你可以参考angular2-quickstart-on-azure了解更多信息。

任何进一步的关注，请随时让我知道。

Answer 2

或者，你应该能够用semver来定义它：

  "engines":{ "node":"^6.0.0" }, 

应该瞄准最新的6.xx版本。

另一个有效的写法是：

  "engines":{ "node":">=6.2.0 <6.5" }, 

目标在6.2.0和6.5.0之间。

请参阅npm的package.json引擎规范 。
