如何为hubot设置node_path

Question

我正在使用hubot (特别是hubot-hipchat)，并希望使用https://github.com/scriby/asyncblock节点模块。在hubot中导入/请求节点模块的正确方式是什么？

我cd到我安装了hubot (~/hubot)的位置

编辑hubot/packages.json将hubot-hipchat，asyncblock添加到依赖项部分。

  "dependencies": {
    "hubot-hipchat": ">= 1.0.4",
    "hubot": "2.1.4",
    "hubot-scripts": ">=2.0.4",
    "optparse": "1.0.3",
    "asyncblock": "2.0.8"
  }

然后，我在我的scripts/test.cafe脚本中执行以下操作：

asyncblock = require('asyncblock')

当我启动hubot时，我得到错误:错误错误:找不到模块'asyncblock‘

~/hubot/node_modules/asyncblock存在。然后我试着这样做：

require.paths.push('/home/ubuntu/hubot/node_modules')

现在我没有得到can't find错误，但我得到了一个新的错误：

ERROR Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead.

我做错了什么？

我只是想在运行hubot的ubuntu服务器上执行一个系统命令：

  asyncblock((flow) ->
    exec('node -v', flow.add())
    result = flow.wait()
    msg.send result
  )

编辑:因此，如果我将NODE_PATH环境变量设置为以下值，它就会正常工作：

env NODE_PATH="/usr/lib/nodejs:/usr/share/javascript:/home/ubuntu/hubot/node_modules"

为什么它不按照惯例在hubot/node_modules中查找？

Answer 1

你的require('asyncblock')脚本在哪里？它是否在~/hubot的子目录中？如果不是，它的require函数将不会在~/hubot/node_modules中查找。

检查该脚本中module.paths的值，以查看该脚本的require查看的所有非全局路径。

Answer 2

这里的问题是您引用的npm模块没有添加到您的项目中。从您的hubot文件夹的根目录中运行以下代码：

npm install --save asyncblock

这会将异步块另存为package.json文件中的依赖项。因此，如果你部署到heroku或open shift或任何其他云服务，该服务将知道自动下载模块，以便它可用于你的机器人。

完成上述任务后

asyncblock= require 'asyncblock'

是正确的使用咖啡-脚本

Answer 3

这样做要简单得多。我也在使用hubot和hipchat。你所需要做的就是：

cd hubot-dir;
npm install asyncblock

下面是你应该注意的：
