How to run the pdf.js node examples?
问题
我正在尝试运行 pdf.js 的节点示例，例如 getinfo.js。但是出现了以下错误：
C:\Repositories\pdf.js>node getinfo.js
node:internal/modules/cjs/loader:1080
throw err;
^
Error: Cannot find module 'pdfjs-dist/legacy/build/pdf.js'
Require stack:

code: 'MODULE_NOT_FOUND',
requireStack: [ 'C:\\Repositories\\pdf.js\\getinfo.js' ]
}
Node.js v18.16.1
这是我之前做的步骤：
git clone https://github.com/mozilla/pdf.js.git
cd pdf.js
npm install
npm install -g gulp-cli
gulp generic
gulp generic-legacy
cd examples
cd node
node getinfo.js -> 出现上述错误
那么，如何运行节点示例？为什么是 'pdfjs-dist/legacy/build/pdf.js'？是否可以更新到当前版本？是否有一个最新的示例供参考？

}
Node.js v18.16.1
This is what I did before:
git clone https://github.com/mozilla/pdf.js.git
cd pdf.js
npm install
npm install -g gulp-cli
gulp generic
gulp generic-legacy
cd examples
cd node
node getinfo.js -> gives error mentioned above
So, how to get the node examples running? Also, why is it 'pdfjs-dist/legacy/build/pdf.js'? Can one update to the current version / is there an up to date example to get started?

需要安装 pdfjs-dist。或者也可以这样操作:
运行 gulp dist-install 以生成 'pdfjs-dist' npm 包文件。
我可以调整示例并将
const pdfjsLib = require("pdfjs-dist/legacy/build/pdf.js");
更改为
const pdfjsLib = require("pdfjs-dist/build/pdf.js");
无任何问题（对于 getinfo.js）。
英文:
Needed to install pdfjs-dist. Alternatively that might work too:
> Run gulp dist-install to generate 'pdfjs-dist' npm package files.
I could adapt the sample and change
const pdfjsLib = require("pdfjs-dist/legacy/build/pdf.js");
to
const pdfjsLib = require("pdfjs-dist/build/pdf.js");
without any issues (for getinfo.js)
