  • yargs 的 bool 默认是 false，除非配置 undefined
  • ci 的时候，是构建 js 后，再跑 cov 的，此时 typescript = false
  • 按之前的逻辑就会去读取 pkg，拿到 typescript = true，在 egg-core 里面就挂掉了

argv.typescript 为 true / false 的时候， 即显式设置时，都不能读取 pkg，所以只能支持 undefined

还是 cov 那个问题，那天群里面说，线上真实运行的是编译后的 js，所以 ci 的测试，也要针对构建后的 js 进行测试，所以这时候的 cov 要传递 --no-ts

编译后的和 extension 其实是一样的

所以我们 cov 和 ci 都是走 ts-node ？
