Question

npm版本是4.6.1 另请参阅github link

我创建了一个普通的hello world应用程序并尝试了

create-react-native-app HelloWorldVatsal

它创建了应用程序并加载了所有模块等，并在终端上发出了成功消息

之后如下所示

cd HelloWorldVatsal
npm start

HelloWorldVatsal@0.1.0 start /home/mvix-vatsal/HelloWorldVatsal
react-native-scripts start

14:52:58: Unable to start server
  See https://git.io/v5vcn for more information, either install watchman or run the following snippet:
    sudo sysctl -w fs.inotify.max_user_instances=1024
    sudo sysctl -w fs.inotify.max_user_watches=12288

Answer 1

正如您从下面显示的错误消息行中看到的那样;

See https://git.io/v5vcn for more information, either install watchman or run the following snippet:
    sudo sysctl -w fs.inotify.max_user_instances=1024
    sudo sysctl -w fs.inotify.max_user_watches=12288

您需要安装watchman或运行错误消息中显示的代码段。

Answer 2

安装watchman只为我工作：D

我的系统（mac） - ＆gt; OSX 10.12.3

brew update

brew install watchman

Answer 3

在Mac上运行以下命令对我有用：

sudo sysctl -w kern.maxfiles = 5242880

sudo sysctl -w kern.maxfilesperproc = 524288

npm开始不起作用create-react-native-app
