Javascript 角度2快速启动PC错误
我正在试用关于angular 2的官方打字稿。我遵循了所有步骤,当我运行Javascript 角度2快速启动PC错误,javascript,node.js,angular,Javascript,Node.js,Angular,我正在试用关于angular 2的官方打字稿。我遵循了所有步骤,当我运行npm start时,它确实在我的firefox浏览器上弹出了我的第一个Angular 2应用程序的消息 但是,当我检查控制台时,我发现错误消息: Error: watch node_modules/angular2/es6/dev/src/common/directives/ng_if.js ENOSPC 我不知道这是否与我之前在项目根文件夹上运行npm install时收到的警告消息有关: npm WARN insta

我通过增加inotify观察者的数量来解决这个问题:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
此错误也可能在其他过程中发生(例如,更现代的
ng-serve
)
虽然如果您不信任代码,应该避免此错误,但使用
sudo
运行命令将很快修复此错误。磁盘是否已满?用户是否有正确的权限在需要写入的地方写入?@m90不,它还没有满,我有权限在项目文件夹中写入。也许这对您有帮助:此外,这与:这肯定解决了angular 2教程()上运行npm start
时出现的eNOPC
问题,谢谢你的分享!为什么有这么多依赖关系?对于一个简单的“hello world”项目,node_modules文件夹中有374个目录,这似乎有点过分了。将sudo授予这样一个有风险的命令是不明智的,因为可以通过npm依赖项运行的源代码来源几乎是无限多样的。
