Question

我的package.json看起来像下面复制但我在部署时遇到错误。我收到错误：没有可用的node.js版本匹配应用程序的版本约束。任何人都可以告诉我们错误。我已经给出了这个版本，因为WEBSITE_NODE_DEFAULT_VERSION的值为6.2.1。

PFB快照：

Answer 1

您选择的node.js版本6.2.1在Azure网络应用程序上不可用。该平台上可用的Node.js版本是：

`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，或者您可以尝试选择上述可用版本之一。

此外，您可以参考angular2-quickstart-on-azure更多信息。

如有任何疑问，请随时告诉我。

Answer 2

或者，您应该可以使用semver来定义它更宽松：

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

应定位最新的6.x.x版本。

另一种有效的写作方式是：

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

在6.2.0和6.5.0之间定位。

请参阅npm的package.json engines specification。
