为什么我无法运行 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 时遇到问题。我点击了下面的链接，但仍然存在错误。我的操作系统有问题吗？我尝试删除node_modules，运行npm install --global cross-env。并再次运行 NPM install。

“cross-env”不被识别为内部或外部命令，

我运行时总是遇到的错误

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

首次运行

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。

Answer 4

就我而言，我有旧版本的node.js 所以我刚刚安装了我需要的版本：

sudo npm install n -g

sudo n stable

或者可以尝试使用最新的：

sudo n latest

Answer 5

如果您使用

nvm

，您需要使用项目版本。命令对我有帮助：

1. 使用默认版本节点：

   nvm use system

2. 删除node_modules

   rm -rf node_modules

   和

   rm -f package-lock.json

3. 清除缓存

   npm cache clear --force

4. 命令完成

   npm i

Answer 6

就我而言，我尝试运行 Next.js 项目版本 13.5.6，但遇到了以下错误：

Starting: next dev
node:internal/modules/cjs/loader:1078
  throw err;
  ^

Error: Cannot find module '/Users/moysantanav/Documents/Projects/BuhoHubWeb/next'

}

这是修复使用

npm install cross-env

npm install 

然后运行

npm run dev
