5 years ago 如果是OSX, 最好是安装 watchman brew install watchman, create-react-app 需要这个监视文件改动, 如果没有的话会使用 node 自带的 fs 模块监视文件, 但是因为文件太多, 超过了系统允许的最大数量, 所以无法启动(Unable to start server)
错误信息中已经提醒你如果不想安装 watchman 可以改动系统参数, 但我记得重启就会失效.
sudo sysctl -w kern.maxfiles=5242880
sudo sysctl -w kern.maxfilesperproc=524288
错误信息如下： 15:54:29: Unable to start server See https://git.io/v5vcn for more information, either install watchman or run the following snippet: sudo sysctl -w kern.maxfiles=5242880 sudo sysctl -w kern.maxfilesperproc=524288

有人遇到这问题吗？重新安装了依赖也不起作用
