我正在 Windows 10 机器上的 Docker Toolbox 实例上安装 Laravel 项目（版本 6.17.1）。在我的 Docker 实例中，我可以composer install很好地运行npm i，但是当我运行时npm run dev，但最初，我收到了有关跨环境的错误：
sh: 1: cross-env: not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! @ development: `cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js`
npm ERR! spawn ENOENT
npm ERR!
npm ERR! Failed at the @ development script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
然后我手动安装了 cross-env，现在我知道这个节点模块已经安装，因为在我的 node_modules 文件夹中我可以看到一个 cross-env 文件夹 - 但是，错误消息仍然存在。
查看其他一些答案，我可以看到我可能需要更改我的 package.json 文件 - 脚本最初看起来像这样：
"scripts": {
"dev": "npm run development",
"development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "npm run development -- --watch",
"watch-poll": "npm run watch -- --watch-poll",
"hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"prod": "npm run production",
"production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},
按照florencebib 的示例，我的 package.json 现在看起来像：
{
"private": true,
"scripts": {
"dev": "node node_modules/cross-env/src/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "node node_modules/cross-env/src/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "node node_modules/cross-env/src/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "node node_modules/cross-env/src/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "node node_modules/cross-env/src/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},

}
由于我更新rm -rf node_modules rm package-lock.json yarn.lock npm cache clear --force了 package.json，我运行、安装节点模块并再次尝试运行 dev，但现在我收到以下错误：

在达到这一点之前我尝试过的其他事情：
- npm install --save-dev 跨环境
- npm i 跨环境 -g
- npm 重建
- 删除和重新安装节点模块
- 清除缓存
- 使用纱线代替 npm
我做错了什么导致内存泄漏吗？还是我在这件事上走错路了？任何建议表示赞赏。
