無法在expressjs中安裝jQuery文件上傳

Question

我是nodejs的新手。 當我要安裝blueimp-file-upload-expressjs時，會出現以下錯誤。

D:\WorkShop\Express\zipzap>npm install blueimp-file-upload-expressjs --save
npm WARN deprecated lodash-node@2.4.1: This package is discontinued. Use lodash@^4.0.0.

> lwip@0.0.6 install D:\WorkShop\Express\zipzap\node_modules\lwip

如何安裝和使用這個插件？ 也無法理解什么是實際錯誤。 我正在研究nodejs。 那為什么要求python路徑？

Answer 1

@Dipankar Naskar：那為什么要問python路徑？

因為Node.js是用GYP構建的 - 用Python編寫的跨平台構建工具。 還有一些其他構建步驟在Python中實現。 因此，從源代碼構建節點需要Python。

@Dipankar Naskar：如何安裝它並使用這個插件？

這是幾乎情況下的解決方案。

Node.js的配置步驟現在應該如下：

安裝VC ++ Build Tools Technical Preview ，選擇Custom Install ，然后選擇Windows 8.1和Windows 10 SDK。

💡[僅限Windows 7]需要.NET Framework 4.5.1

安裝Python 2.7或3.6，並將其添加到PATH ， npm config set python python2.7

啟動cmd， npm config set msvs_version 2015 --global （這不是npm config set msvs_version 2015 --global都是npm install [package name] --msvs_version=2015 ）

SO MUCH npm install 🎉

注意：有了你的問題，你只需安裝Python，將它添加到你的PATH ， npm config set python python2.7 。
