[文章]【鸿蒙IPC开发板开发板体验】编译才是灵魂，也是踩坑的开始

完成第一步后，进入了第二步编译，正式开始了不断试错，

以上是我下载的源码版本

可以通过各种代码仓库下载源码，自有搭建

@ubuntu:~$ npm install -g @ohos/hpm-cli

npm WARN deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

npm WARN deprecated @babel/polyfill@7.4.4: ��� This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the @babel/polyfill docs (https://babeljs.io/docs/en/babel-polyfill) for more information.

npm WARN checkPermissions Missing write access to /usr/lib/node_modules

踩过一些坑之后 找到了官方 ，官方不建议 在 老的代码上进行开发
