【问题描述】：

我有一个 json 文件（给定日期的西班牙电价），我想以纯文本格式提取给定 geo_name 的 value：“Península”

文件如下：

  "indicator": {
    "name": "Término de facturación de energía activa del PVPC 2.0TD",

        "geo_id": 8745,
        "geo_name": "Melilla"
      }
    ]
  }
}

我的“最佳猜测”是

$ jq '.indicator.values[] | .value | select(.indicator.values[] | .geo_name=="Península")' myfile.json

但我得到了一个

jq: error: Cannot index number with string

我可以改变什么以获得正确的结果？

非常感谢您的回答对我有用的是：jq '.indicator.values[] | select(.geo_name=="Península") .value' 从我之前的回答中得到这个；不幸的是，它似乎已被删除....
