认真读了文档，但设置还是有问题。
http://mydomain:1200/twitter/followings/mytwitter_Username

出现错误：
Error: lacking twitter token for user mytwitter_Username at module.exports (/app/lib/routes/twitter/followings.js:10:15) at dispatch (/app/node_modules/koa-compose/index.js:42:32) at /app/node_modules/@koa/router/lib/router.js:368:16 at dispatch (/app/node_modules/koa-compose/index.js:42:32) at /app/node_modules/koa-compose/index.js:34:12 at dispatch (/app/node_modules/@koa/router/lib/router.js:373:31) at dispatch (/app/node_modules/koa-compose/index.js:42:32) at cache (/app/lib/middleware/cache.js:203:15) at process._tickCallback (internal/process/next_tick.js:68:7)

在docker container里的变量，我设了三个：

TWITTER_CONSUMER_KEY: 1
TWITTER_CONSUMER_SECRET: 2
TWITTER_TOKEN_(3里的Token ID): 1,2,3,4

请问哪里设错了？

谢谢！
