在 Azure 上部署 Angular2 应用程序时出现节点版本错误

Question

我的 package.json 看起来像下面复制的，但我在部署时遇到错误。我收到错误消息：没有可用的 node.js 版本与应用程序的版本约束相匹配。谁能告诉我错误是什么。我将此版本指定为 WEBSITE_NODE_DEFAULT_VERSION 的值为 6.2.1。

PFB快照：

Answer 1

作为您选择的 node.js 版本 6.2.1，它在 Azure 网络应用程序上不可用。 Node.js 平台上可用的版本是：

`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以上可用版本之一。

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

如有任何疑问，请随时告诉我。

Answer 2

或者，您应该可以使用 semver:

将其定义得更宽松

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

应该以最新的 6.x.x 版本为目标。

另一种有效的写法是：

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

要在 6.2.0 和 6.5.0 之间定位。

查看 npm 的 package.json engines specification。
