Can you access this link?

[Lucas-wdy]

@Chance-fyi Yes, I can

1. Try to see if you can access it from the command line
2. Check if the environment variable VFOX_NODEJS_MIRROR is set.
3. Check if a proxy is set
4. Try setting a proxy for vfox

vfox config proxy.enable true
vfox config proxy.url http://your_host:your_port

这种问题，大多都是网络不好导致的，切换一下nodejs镜像源试试。

vfox search nodejs no available version

设置代理也不行，本机可以访问 https://nodejs.org/dist/index.json

但是，卸载插件重新安装后又可以了 vfox remove nodejs vfox add nodejs
