javascript – Angular 2 quickstart ENOSPC错误

JavaScript 前端之家
前端之家收集整理的这篇文章主要介绍了javascript – Angular 2 quickstart ENOSPC错误，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我正在试用官方 5 Min Quickstart关于角度2的Typescript.我遵循所有步骤,当我运行npm开始它确实在我的Firefox浏览器弹出预期的我的第一个Angular 2应用程序消息.

但是,当我检查控制台时,我发现错误消息：

  1. Error: watch node_modules/angular2/es6/dev/src/common/directives/ng_if.js ENOSPC

当我在项目的根文件夹下运行npm安装时,我不知道是否与我之前收到的警告消息相关：

  1. npm WARN install Couldn't install optional dependency: Unsupported
  2. npm WARN EPACKAGEJSON angular2-quickstart@1.0.0 No description
  3. npm WARN EPACKAGEJSON angular2-quickstart@1.0.0 No repository field.

有人可以告诉我我的做法有什么问题吗？更详细的控制台输出如下所示：

  1. > angular2-quickstart@1.0.0 start /home/ubuntu/jsProjects/angular2-quickstart
  2. > concurrent "npm run tsc:w" "npm run lite"

解决方法

我通过增加知识观察者的数量来解决这个问题： 
  1. echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
