jq:错误:未在< top-level>中定义round/0. [英] jq: error: round/0 is not defined at <top-level>

问题描述

jq中的回合功能不起作用.

round function in jq doesn't work.

$ jq '10.01 | round'
jq: error: round/0 is not defined at <top-level>, line 1:
10.01 | round        
jq: 1 compile error

$ jq --help
jq - commandline JSON processor [version 1.5-1-a5b5cbe]

我需要做什么?

推荐答案

在您的版本中似乎没有round这样的名称.升级jq或使用floor实施round:

Seems like round is unavailable in your build. Either upgrade jq or implement round using floor:

def round: . + 0.5 | floor;

用法示例:

$ jq -n 'def round: . + 0.5 | floor; 10.01 | round'
10
