Hi dominhhai, After upgrading koa-log4js to 2.2.0, it could not work well as complaining: \node_modules\.2.2.0@koa-log4\koa-logger.js:50 return async (ctx, next) => { ^ SyntaxError: Unexpected token ( at Object.exports.runInThisContext (vm.js:76:16) at Module._compile (module.js:542:28) at Object.Module._extensions..js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) at Function.Module._load (module.js:438:3) at Module.require (module.js:497:17) at require (internal/module.js:20:19)

typescript version as: $ tsc -v Version 2.2.1

while v2.1.0 works well; May u kindly help on it, thanks~

@dennyx hi, thanks for your reporting. v2.2.0 use native async-await. If your want to use yield function, please use v2.1.0 instead of.
