win10+node10.13.0+npm6.4.1+puppeteer6.4

安装nodejs和npm

下载地址：

https://nodejs.org/zh-cn/

下载下来直接默认安装就行，安装成功后，看看是否安装成功，如下：

更新npm:

问题1：

C:\Users\Administrator>npm i npm
npm WARN saveError ENOENT: no such file or directory, open 'C:\Users\Administrator\package.json'

解决办法：

npm install -g cnpm --registry=https://registry.npm.taobao.org

安装puppeteer

输入如下命令安装

npm i puppeteer

如下，则说明开始下载安装：
C:\Users\Administrator>npm i puppeteer
> puppeteer@1.10.0 install C:\Users\Administrator\node_modules\puppeteer
> node install.js

注：

有时国外网络问题，一直卡，所有最好通过cnpm安装能快些，如下：

cnpm i puppeteer

安装完成，如下图：

cd D:\Program Files\nodejs\node_modules

D:\Program Files\nodejs\node_modules>cnpm i puppeteer

装完后测试一下,如下：

创建一个js文件，我这里叫hello.js,内容如下：

const puppeteer = require('puppeteer');
 
(async () => {
 const browser = await puppeteer.launch({headless: false});
 const page = await browser.newPage();
 await page.goto('https://www.baidu.com', {waitUntil: 'baidu'});
 await page.pdf({path: 'baidu.pdf', format: 'A4'});
 
 await browser.close();
})();

执行该文件，命令如下：

node hello.js

出现浏览器弹出来，并生成pdf文件就可以了
