我正在尝试开始使用 Scio，并且我使用了他们的 giter8 入门项目。https://github.com/spotify/scio.g8
我在 macOS 上使用 Java 8，尝试使用target/pack/bin/word-count --output=wc命令行或命令行运行项目时出现此错误：
sbt "runMain example.WordCount
--project=xxx
--input=gs://dataflow-samples/shakespeare/kinglear.txt
--output=gs://xxx-xxx.appspot.com/wordcount"

我做错了什么？
我怎样才能让它工作？
