pm2 启动的时候 nodejs 的环境和当前的 nodejs 环境不一致

update                                               (alias) update in-memory PM2 with local PM2

需要用 pm2 update 来刷新内存里面的 pm2

这样的场景通常是因为用了低版本的 nodejs 启动程序, 改代码之后需要用到高版本的特性, 这时候不能用 pm2 restart process.yml 来重启程序.

Using ngrok

First, we'll install a program to expose our local host to the Internet. We'll use ngrok to do this. ngrok is a free download available for all major operating systems.

When you're done with that, you can expose your localhost by running ./ngrok http 4567 on the command line. You should see a line that looks something like this:

Forwarding    http://7e9ea9dc.ngrok.io -> 127.0.0.1:4567
