無法在expressjs中安裝jQuery文件上傳

我是nodejs中的新手。 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.

如何安裝並使用此插件？也不明白什麼是實際的錯誤。 我正在研究nodejs。那麼它爲什麼要求python路徑？

Answer 1

@Dipankar Naskar：那爲什麼要求python路徑？

因爲Node.js是用GYP構建的 - 用Python編寫的跨平臺構建工具。還有一些其他的構建步驟是在Python中實現的。所以Python是從源代碼構建節點所必需的。

@Dipankar Naskar：如何安裝並使用此插件？

這是幾乎情況下的解決方案。

的配置步驟，Node.js的現在應該如下：

安裝VC++ Build Tools Technical Preview，選擇自定義安裝，並選擇在Windows 8.1和Windows 10軟件開發工具包。

[僅限於Windows 7]需要.NET Framework 4.5.1

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

啓動CMD，npm config set msvs_version 2015 --global（這是不是每次都npm install [package name] --msvs_version=2015。 ）

SO SOCHnpm install

注意：有了您的問題，您只需安裝Python，將其添加到您的PATH,npm config set python python2.7。
