- 如何包含它/如何在节点中使用 jsPDF？
- 在尝试使用

Can anybody help me on how to include it in node? And give a 4-5 line demo.
有人可以帮助我如何将它包含在节点中吗？并给出4-5行demo。

You can actually use jspdf directly (npm install jspdfinstead of npm install node-jspdf). Jspdf is currently (v1.3.2) not built with node support in mind, but you can mock the globals like below and get it to work that way. This is a basic example and all features of jspdf will not be available.
您实际上可以直接使用 jspdf（npm install jspdf而不是npm install node-jspdf）。Jspdf 目前 (v1.3.2) 没有考虑到节点支持，但您可以模拟如下的全局变量并让它以这种方式工作。这是一个基本示例，jspdf 的所有功能都将不可用。
global.window = {document: {createElementNS: () => {return {}} }};
global.navigator = {};
global.html2pdf = {};
global.btoa = () => {};
var fs = require('fs');
var jsPDF = require('jspdf');
var doc = new jsPDF();
doc.text("Hello", 10, 10);
var data = doc.output();
fs.writeFileSync('./document.pdf', data, 'binary');
delete global.window;
delete global.html2pdf;
delete global.navigator;
delete global.btoa;

In extension to the answer provided by Simon Bengtsson:
在 Simon Bengtsson 提供的答案的扩展中：
I managed to handle even latin-1 characters by sending the output of jsPdf to encoding:
通过将 jsPdf 的输出发送到编码，我甚至设法处理了 latin-1 字符：
global.window = {document: {createElementNS: () => {return {}} }};
global.navigator = {};
global.btoa = () => {};
var fs = require('fs');
var jsPDF = require('jspdf');
var encoding = require('encoding')
var doc = new jsPDF();
doc.text("Hello??ü???ü?μ?", 10, 10);
var data = doc.output()
var buffer = encoding.convert(data, "Latin_1")
fs.writeFileSync('./document.pdf', buffer);
delete global.window;
delete global.navigator;
delete global.btoa;

I am able to install node-jspdfin Windows.
我可以在 Windows 中安装node-jspdf。
- As suggested download jspdf-master.zipand extract it.
Now use the command:
npm install <location on jspdf-master extract>
- 按照建议下载jspdf-master.zip并解压缩。
现在使用命令：
npm install <location on jspdf-master extract>
After that you can use npm listto see the installation success.
之后就可以使用npm list查看安装成功了。

Node-jspdfmainly uses library jsPDFas the core library to render PDF file
Node-jspdf主要使用库jsPDF作为核心库来渲染PDF文件
but node-jspdfcan only be installed on *unixsystem therefore you can download and install jsPDFmanually by following steps in this file
但node-jspdf只能安装在*unix系统上，因此您可以jsPDF按照此文件中的步骤手动下载和安装
I think you only need to install jsPDFto work with PDF file.
我认为您只需要安装jsPDF即可使用 PDF 文件。

Download your jspdf folder from parallax jspdf. After installing jspdf ( "npm install jspdf" ) you get the jspdf folder inside node-modules. Go inside it and replace the jspdf.min.js by the jspdf.amd.min.js present in the /dist folder inside the jspdf downloaded from parallax
从视差 jspdf 下载您的 jspdf 文件夹。安装 jspdf ( "npm install jspdf" ) 后，您会在节点模块中获得 jspdf 文件夹。进入它并用从视差下载的 jspdf 内的 /dist 文件夹中的 jspdf.amd.min.js 替换 jspdf.min.js
