self signed certificate in certificate chain while runnig npm i for a strapi project

Question

I am trying to setup a Strapi project on my corporate laptop. When I run the command npm i it installs the some modules and when it finally reaches

> sharp@0.26.2 install C:\<path>\Documents\Office\km-service\node_modules\sharp
> (node install/libvips && node install/dll-copy && prebuild-install) || (node-gyp rebuild && node install/dll-copy)

I get these errors:

I have tried the following things but the issue hasn't been fixed yet.

npm config set registry http://registry.npmjs.org/

npm install npm -g --ca=null

npm config set ca=""

npm set strict-ssl false

npm set config set NODE_TLS_REJECT_UNAUTHORIZED=0

I have python 3.9.0 installed on my system and I did install windows-build-tools via npm.

A possible workaround is to manually download the libvips library (use the URL from error description) and place it in global cache folder/_libvips directory (i.e., on Windows the folder is %AppData%/npm-cache/_libvips).
The install task will then use the cached file instead of downloading it.
