Basic example fails due to babel configuration

We've been maintaining a project based on `basic-starter-api-gateway-v1` for about a month now with no issues. We tried to issue an update today and started running into babel configuration errors. I went back to a fresh copy of the standard example out of this repo and I get the same error when running `npm run setup`. It seems to happen in the packaging process.

```

I've attempted to install `babel-plugin-transform-runtime`, which ends up with new errors:

```
Couldn't find preset "env" relative to directory "/Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/regenerator-transform" (While processing preset: "/Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/babel-preset-es2015/lib/index.js")
```

Installing `babel-preset-env` results in yet another error that I can't get past:

```
Error: Options {"loose":true} passed to /Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/babel-preset-env/lib/index.js which does not accept options. (While processing preset: "/Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/babel-preset-env/lib/index.js") (While processing preset: "/Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/babel-preset-env/lib/index.js") (While processing preset: "/Users/tylerfisher/src/serverless-express/examples/basic-starter-api-gateway-v1/node_modules/babel-preset-es2015/lib/index.js")
```

I'm not even sure at what point babel is invoked, so it's hard to trace down where to fix this issue.

Bắt đầu bằng cách chạy `npm run setup` trong ví dụ `basic-starter-api-gateway-v1` và truy vết nơi quy trình đóng gói gọi Babel. Kiểm tra các preset và plugin Babel liên quan được hiển thị trong các lỗi, bao gồm `babel-preset-es2015`, `babel-preset-env` và `babel-plugin-transform-runtime`. Công việc được xem là hoàn tất khi ví dụ tiêu chuẩn hoàn tất quá trình thiết lập mà không cần cài đặt thủ công các gói Babel bổ sung.
