我無法在ubuntu16.04上運行nodejs

Question

我在我的ubuntu16.04上安裝了nodejs。但我不能運行這個。當我寫一個命令NPM運行開發它顯示了以下錯誤：

    throw err; 
    ^

在這裏，我也安裝NPM-調試 .LOG使用下面的命令，但我依然面臨這個問題

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

Answer 1

它在的package.json「腳本」配置有問題。請將package.json文件中的「腳本」部分替換爲以下內容：

"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" 

然後重新安裝節點模塊。

或者，作爲另一種選擇，按照Jeffrey Way的建議在以下cross-env issue page的底部找到。

我在升級cross-env軟件包時遇到同樣的問題。

以前它是：

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

我固定的package.json文件，並犯了這樣的路徑：

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

，並且不發生同樣的問題再次我剛剛設置的版本在依賴關係中交叉環境是嚴格的。
