为什么我不能运行 Npm run dev？

Question

伙计们，你们能帮我解决这个问题吗？我在为我的 Laravel Mix运行npm run dev 时遇到了问题。我按照下面的链接，但仍然存在错误。我的操作系统有问题吗？我试图删除 node_modules，运行 npm install --global cross-env。并再次运行 NPM 安装。

'cross-env' 不被识别为内部或外部命令，

https://github.com/JeffreyWay/laravel-mix/issues/478

我运行时总是遇到错误npm run dev：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
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! Exit status 1
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.

Answer 1

第一次运行

npm install cross-env

npm install 

然后运行

npm run dev

Answer 2

简单步骤：

1. npm 缓存清除 --force
2. 删除node_modules和package-lock.json
3. npm 安装
4. npm 运行开发

Answer 3

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
npm install

基本上删除node_modules文件夹和package-lock.json文件，清除缓存并执行npm安装。为我工作。
