搭建过程二三事

• yarn start启动提示

20:24:57: 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=12288error Command failed with exit code 1.info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

• /etc/sysctl.conf最后面添加下面两行，解决上面的提示

# gedit /etc/sysctl.conffs.inotify.max_user_instances=1024fs.inotify.max_user_watches=12288

• su用户第一次密码设置

# 按提示输入密码即可sudu passwd
