eosjs编译报错

[lacs34]

我希望在网页上访问eos服务，根据eos官网的介绍，通过npm下载了eosjs，命令如下：
npm init -y
npm install eosjs@beta
结果发现eosjs是用typescript写的，如果要在前端使用，需要编译成js，因为发现eosjs里提供了webpack配置，所以准备通过webpack来编译typescript，命令如下：
npm install webpack webpack-cli typescript ts-loader
./node_modules/.bin/webpack --config ./webpack.debug.js
结果报错如下：

看起来编译器根本不认typescript的代码，我是哪里配置错了么？
