Javascript 我如何知道我的项目的最小node.js版本？

NPM是否有基于可用项目模块列出最小节点版本依赖关系的命令？

您应该能够检查package.json以了解以下内容：

  "engines": {
    "node": ">=0.10.0"
  }

我认为您应该尝试使用npm ls命令

否。没有内置的方法递归检查当前包及其依赖项，并将

引擎.node

需求整理成一个内聚的整体

如果您使用的是类unix系统，则可以尝试以下命令：

find . -name package.json | xargs grep -h node\": | sort | uniq -c

它将为您提供如下输出：

    1     "gnode": "0.1.0",
    36     "node": "*"
    1     "node": "0.10.x || 0.8.x"
    1     "node": "0.4 || >=0.5.8"
    1     "node": ">= 0.10.0"
    3     "node": ">= 0.4"
    3     "node": ">= 0.4.0"
    2     "node": ">= 0.4.1 < 0.5.0"
    2     "node": ">= 0.6"
    1     "node": ">= 0.6.6"
    8     "node": ">= 0.8"
    3     "node": ">= 0.8.0"
    1     "node": ">=0.1.90"
    2     "node": ">=0.10.0"
    5     "node": ">=0.4"
    9     "node": ">=0.4.0"
    3     "node": ">=0.4.12"
    3     "node": ">=0.4.9"
    5     "node": ">=0.6"
    5     "node": ">=0.8"
    19     "node": ">=0.8.0"
    1     "node": ">=0.8.x"
    1   "engines": { "node": ">= 0.4.0" }
    1   , "dnode": "10.999.14234"

您可以使用ls引擎包

find . -name package.json | xargs grep node\":

> ls-engines
