阵营原住民 - NPM启动不启动

Question

我努力工作，在Fedora的26阵营本地人，我也跟着facebook tutorial再说吧。

一切都进行得非常顺利，直到我试图与NPM

npm start

启动应用程序 而收到此错误：

> cardbook@0.1.0 start $HOME/cardbook 
> react-native-scripts start 

9:31:54 AM: Starting packager...

附加信息：

任何纯洁和善良的灵魂能帮助我吗？

我跑我的应用程序，现在我的手机上。我采用了一种启发式的方法，试图快速解决问题，然后信息缺乏。无论如何，我解决了它这样的：

首先，我卸载守望：

$ sudo make uninstall 

因此，与纱线（请注意，我没有使用NPM，它仍然无法正常工作），我收到以下提示：

yarn start 
yarn run v1.1.0 
$ react-native-scripts start 
11:15:08 AM: 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 
error Command failed with exit code 1. 

很显然，我跟着指示：

sudo sysctl -w fs.inotify.max_user_instances=1024 
sudo sysctl -w fs.inotify.max_user_watches=12288 

而且收到了我的QR码与更迭。
