我无法在ubuntu16.04上运行nodejs

Question

我在我的ubuntu16.04上安装了nodejs。但我不能运行这个。当我写一个命令NPM运行开发它显示了以下错误：

在这里，我也安装NPM-调试 .LOG使用下面的命令，但我依然面临这个问题

npm install --save debug-log enter image description here

Answer 1

它在的package.json“脚本”配置有问题。请将package.json文件中的“脚本”部分替换为以下内容：

"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，作为另一种选择，按照Jeffrey Way的建议在以下cross-env issue page的底部找到。

我在升级cross-env软件包时遇到同样的问题。

以前它是：

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

我固定的package.json文件，并犯了这样的路径：

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

，并且不发生同样的问题再次我刚刚设置的版本在依赖关系中交叉环境是严格的。
