Npm install try to install dependency not in package.json and prints error - npm

Question

On a project, I try to npm install for the first time. But it tries to install the dependency "js-xlsx" but i can't see it in package.json
Moreover, it prints error and can't install it, and install nothing else .
The error when npm install :
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
Here is my package.json :

Why does it try to install it ? Does it need it for another dependency ?
How can i solve this ?

So, I needed to configure not only the proxy of npm, but git also :
git config --global http.proxy http://proxyUsername:proxyPassword#proxy.server.com:port
git config --global https.proxy http://proxyUsername:proxyPassword#proxy.server.com:port
git config http.sslVerify false
