我无法在ubuntu16.04上运行nodejs

我在我的ubuntu16.04上安装了nodejs。 但是我不能运行这个。 当我写一个命令npm运行dev它显示以下错误：

---

在这里我也使用下面的命令安装了npm-debug .log，但是仍然面临着这个问题

Answer 1

使用npm install将模块安装到当前目录中（在名为node_modules的子目录中）。

本指南对我也很有帮助： https : //www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-16-04

Answer 2

这是package.json“scripts”configuration中的一个问题。 将package.json文件中的“scripts”部分replace为以下内容：

 "dev": "cross-env NODE_ENV=development webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "watch": "cross-env NODE_ENV=development webpack --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js", "hot": "cross-env NODE_ENV=development webpack-dev-server --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js", "production": "cross-env NODE_ENV=production webpack --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js" 

然后重新安装节点模块。

或者，作为另一种select，请按照Jeffrey Way的build议在下面的跨环境问题页面底部find。

Answer 3

升级cross-env软件包时遇到同样的问题。

以前是这样的：

 node node_modules/cross-env/bin/cross-env.js 

我已经修复了package.json文件，并创build了这样的path：

 node_modules/cross-env/dist/bin/cross-env.js 

为了不再发生同样的问题，我只是在依赖中设置了cross-env的版本。
