node.js - 在 heroku 上安装 jade 时出错

Question

将我的 node.js-app 推送到 Heroku 时出现错误。它曾经有效，但现在由于某种原因，它失败了。

当我推送到 Heroku 时，我得到以下信息:

-----> Node.js app detected
-----> Resolving engine versions
   Using Node.js version: 0.6.13
   Using npm version: 1.1.4

 !     Heroku push rejected, failed to compile Node.js app

我的 package.json 如下:

{
  "name": "myAppName",
  "version": "0.0.1",
  "dependencies": {
      "express": "2.5.9",
      "mongoose":"3.5.2",
      "jade": "0.15.4",
      "ejs": "0.7.1"
      },
  "engines": {
    "node": "0.6.13",
    "npm": "1.1.4"
  }
}

因为它说“拒绝删除:...”我认为这可能是 Heroku 上的异常错误，所以我尝试将它推送到新的 Heroku 应用程序，但我得到了同样的错误。

有什么问题吗？是我的版本吗？一切都在本地(Windows)运行良好。任何帮助将不胜感激。

您正在使用旧的 node.js。尝试将以下内容添加到 package.json:

  "engines": {
        "node": "0.8.x",
        "npm": "1.1.x"
  },

您可以通过登录系统更仔细地检查事物。首先你需要安装Heroku Toolbelt (如果你还没有)。然后:

heroku login

和

heroku run bash --app yourapp

这将为您的 heroku 安装提供一个 bash。导航到 /tmp (cd/tmp) 并查看那里剩下的内容。尝试手动删除它 (rm -rf whatisleft)。

你的 jade 版本也已经过时了(仍然)。我用 jade 安装的 heroku 有:

"jade": "*"

最后，不要将 node_modules 添加到源代码管理中。所以将它添加到您的 .gitignore 文件中。
