假设您使用的是Linux/OSX，您可以尝试以下操作：
find ./apps/* -maxdepth 1 -name package.json -execdir npm install \;
论据：

./apps/*-搜索的路径。我建议在这里非常具体，以避免它拾取其他 node_modules 目录中的package.json文件（参见下面的maxdepth）。
-maxdepth 1-仅遍历搜索路径中的深度1（即当前目录-不进入子目录）
-名称软件包.json-要在搜索中匹配的文件名
-执行目录npm安装;-对于搜索中的每个结果，在保存文件的目录中运行 npm install（在本例中为 package.json）。注意，转义分号的反斜杠必须在JSON文件中进行转义。

把这个放在你的根 package.json 的postinstall钩子中，它会在你每次执行 npm install 时运行：

"scripts": {
    "postinstall": "find ./apps/* -name package.json -maxdepth 1 -execdir npm install \\;"
}

对于跨平台支持（包括Windows），您可以尝试我的解决方案。Pure Node.js
将其作为“preinstall”npm脚本运行

const path = require('path')
const fs = require('fs')
const child_process = require('child_process')

const root = process.cwd()
npm_install_recursive(root)

function npm_install_recursive(folder)
{
    const has_package_json = fs.existsSync(path.join(folder, 'package.json'))

    if (!has_package_json && path.basename(folder) !== 'code')
    {
        return
    }

    // Since this script is intended to be run as a "preinstall" command,
    // skip the root folder, because it will be `npm install`ed in the end.
    if (has_package_json)
    {
        if (folder === root)
        {
            console.log('===================================================================')
            console.log(`Performing "npm install" inside root folder`)
            console.log('===================================================================')
        }
        else
        {
            console.log('===================================================================')
            console.log(`Performing "npm install" inside ${folder === root ? 'root folder' : './' + path.relative(root, folder)}`)
            console.log('===================================================================')
        }

        npm_install(folder)
    }

    for (let subfolder of subfolders(folder))
    {
        npm_install_recursive(subfolder)
    }
}

function npm_install(where)
{
    child_process.execSync('npm install', { cwd: where, env: process.env, stdio: 'inherit' })
}

function subfolders(folder)
{
    return fs.readdirSync(folder)
        .filter(subfolder => fs.statSync(path.join(folder, subfolder)).isDirectory())
        .filter(subfolder => subfolder !== 'node_modules' && subfolder[0] !== '.')
        .map(subfolder => path.join(folder, subfolder))
}
