解决办法：我执行命令的位置是/home/gjj/xxx，这是一个用户目录，出现上面的原因是空间不足。我怀疑是此目录空间的问题，你可以先将项目移至/usr/local/xxx下再次npm start，如果还不行，请参看一下方案，此方案来自https://stackoverflow.com/questions/22475849/node-js-error-enospc

执行如下命令：

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

对于Arch Linux，将下面这行添加到/etc/sysctl.d/99-sysctl.conf文件中：

fs.inotify.max_user_watches=524288

vim /etc/sysctl.d/-sysctl.conf
#添加到最后
fs.inotify.max_user_watches=524288

#完成后执行

sysctl --system
