在一个项目中，我第一次尝试npm安装，但是它尝试安装依赖项"js-xlsx"，但是我在package.json中看不到它
此外，它打印错误，不能安装它，并安装没有别的.
npm安装时的错误：

npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm ERR! Error while executing:
npm ERR! C:\Program Files\Git\mingw64\bin\git.EXE ls-remote -h -t https://github.com/securedeveloper/js-xlsx.git
npm ERR!
npm ERR! fatal: unable to access 'https://github.com/securedeveloper/js-xlsx.git/': Could not resolve host: github.com
npm ERR!
npm ERR! exited with error code: 128

下面是我的package.json：

为什么它要安装它？它是否需要它作为其他依赖项？
我该怎么解决这个问题？
