angular项目执行npm run dev 时报错解决Depr

启动angular项目时，一直启动不起来，报以下错误，node版本也没有问题，查看是环境变量的问题。

(node:61471) [DEP0111] DeprecationWarning: Access to process.binding('http_parser') is deprecated.

(Use `node --trace-deprecation ...` to show where the warning was created)

Error: error:0308010C:digital envelope routines::unsupported

解决方法: 

在terminal执行以下两行指令，设置一下环境变量，重新运行angular项目即可

export NODE_OPTIONS=--openssl-legacy-provider  

set NODE_OPTIONS=--openssl-legacy-provider

然后再重新运行即可解决
