Question

我是一个新的node.js开发人员。我正在尝试将我的node.js应用程序推送到Heroku，但我不断收到一些错误，但不知道如何修复它。

   Pruning any extraneous modules
   Installing node modules (package.json)

请帮帮我。感谢。

Answer 1

我已经解决了这个问题。节点4.x不支持Contextify。所以我将节点降级到0.10.x，然后工作正常。

抱歉我的声音。

Answer 2

我的第一个想法是查看package.json文件并检查错误。另请查看package.json中包含的versions of each npm package并确保它们是最新版本。

package.json中的define the latest version of node。

Javascript /节点库可以定期更新，如果您正在阅读教程，则可能需要更新一些软件包版本
