记一个jupyter启用扩展时的错误 PermissionError: [Errno 13] Permission denied: ‘/usr/etc‘

jupyter安装了扩展，启用扩展时，发现写入目录是/usr/etc，因为没有权限会报错

jupyter serverextension enable jupyterlab_sql --py --sys-prefix
Enabling: jupyterlab_sql
- Writing config: /usr/etc/jupyter
...
PermissionError: [Errno 13] Permission denied: '/usr/etc'

Permission denied when enabling widgetsnbextension · Issue #1731 · jupyter/notebook · GitHub

去除--sys-prefix参数即可
