在 predictionio 中使用 pio build --verbose 构建推荐引擎时出错

Question

我正在尝试将 Predicitionio 与我的应用程序集成。我按照 Quick start 中的步骤操作我停留在第 5 步，将引擎部署为服务。我无法使用 pio build --verbose 构建推荐。当我执行 pio build --verbose.

时打印了以下日志

请帮我解决这个问题。

Answer 1

原因是'pio'没有设置为环境变量。所以我按如下方式执行构建引擎。

/home/PredictionIO/PredictionIO-0.9.6/bin/pio build --verbose

那对我有用
