无法启动服务器，npm start 给出错误

Question

我尝试使用 npm start 启动开发服务器

所有安装程序均按照https://facebook.github.io/react-native/docs/getting-started上的说明进行

我收到如下错误：

在/home/akash/appme中寻找JS文件

加载依赖图...internal/fs/watchers.js:173 抛出错误； ^

Answer 1

它达到了您系统的文件观察者限制

试试echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

Answer 2

在 VSCode 中尝试编辑 setting.json 文件 --> 首选项 --> 设置 --> 打开设置

并排除特定的工作区目录，例如

"files.watcherExclude": {
"**/.git/objects/**": true,
"**/.git/subtree-cache/**": true,
"**/node_modules/*/**": true

}
