我通过 create-react-app 创建了一个新项目。项目成功创建后，我试图通过点击命令yarn start 来启动项目，但它会引发一个未处理的错误。

信用：@robininfo-edsx “当前错误是 ENOSPC（空间不足）它与权限没有直接关系，但通常与磁盘使用情况以及当您达到可以观看的文件限制时有关。作为 root，watch 的限制可能比正常使用要大，这就是为什么 sudo 解决问题但是以 root 身份运行应用程序是不可取的。尝试增加可观看文件的限制 https://stackoverflow.com/questions/22475849/node-js-error-enospc/32600959#32600959"
