三、常见问题
1、提示bufferutil包错误，报错信息如下：
16959 verbose stack Error: bufferutil@1.3.0 install: `node-gyp rebuild`
16959 verbose stack Exit status 1
16959 verbose stack at EventEmitter.<anonymous> (/usr/local/lib/node_modules/npm/node_modules/npm-lifecycle/index.js:301:16)

16968 error Exit status 1
16969 error Failed at the bufferutil@1.3.0 install script.
解决方案：降低node.js版本，最好为8.X系列 !~
2、提示/usr/local/lib/node_modules 目录没有写权限，报错信息如下：
553 error Error: EACCES: permission denied, access '/usr/local/lib/node_modules/stf/node_modules/@slack/client/node_modules/async'
2553 error { Error: EACCES: permission denied, access '/usr/local/lib/node_modules/stf/node_modules/@slack/client/node_modules/async'
2553 error stack: 'Error: EACCES: permission denied, access \'/usr/local/lib/node_modules/stf/node_modules/@slack/client/node_modules/async\'',
2553 error errno: -13,
2553 error code: 'EACCES',
2553 error syscall: 'access',
2553 error path: '/usr/local/lib/node_modules/stf/node_modules/@slack/client/node_modules/async' }
2554 error The operation was rejected by your operating system.
2554 error It is likely you do not have the permissions to access this file as the current user
2554 error
2554 error If you believe this might be a permissions issue, please double-check the
2554 error permissions of the file and its containing directories, or try running
2554 error the command again as root/Administrator (though this is not recommended).
2555 verbose exit [ -13, true ]
解决方案：
1、删除原有stf文件夹，重新安装，千万别用sudo来执行安装。
rm -rf /usr/local/lib/node_modules/stf/
2、给/usr/local/lib/node_modules/stf/赋予权限，更改用户及所属组
chown 当前用户:当前用户的默认组 -R 目录
