安装 gulp 和 pdf.js 的问题

Question

我正在关注this 并尝试使用 pdf.js。我已经下载并提取了库，现在我试图按照页面上的说明在全局范围内安装 gulp，但是当我运行命令时

C:\Users\xx\Desktop\pdfSearch2>npm install -g gulp-cli

我收到错误：

知道我做错了什么吗？ 谢谢

编辑：所以运行这个C:\Users\antoniob\Desktop\pdfSearch2>npm config set strict-ssl=false 已经工作了，但现在我似乎无法安装 pdf.js 依赖项：

C:\Users\xx\Desktop\pdfSearch2>npm install
npm WARN enoent ENOENT: no such file or directory, open 'C:\Users\xx\Desktop\pdfSearch2\package.json'
npm WARN pdfSearch2 No description
npm WARN pdfSearch2 No repository field.
npm WARN pdfSearch2 No README data
npm WARN pdfSearch2 No license field.

我最近遇到了这个问题，可能是由不同的原因引起的。 但通常情况下，您的网络背后的防火墙或代理会导致此错误。

我的解决方案是npm config set strict-ssl=false 命令，它取消了 npm 对 SSL 证书的检查。但请注意，此解决方案不安全，最好正确配置防火墙或代理。所以安装包后运行npm config set strict-ssl=true 命令。
