Don't know what error is related to, I think it is not downloading libvips or is it related to sharp, then how to install sharp cause it is also throwing an error when I am installing it via npm install sharp

• I have tried reinstalling everything, I have installed nodejs 12.13.0
• Then I installed NVM v1.1.7
• Then I installed ionic Cordova
• After I started a new project using ionic
• Then I prepared project for Cordova "ionic cordova prepare", it showed following warning

Log:

**[WARN] No platforms added to this project. Cannot prepare native platforms without any installed.**

* Then I added platform via **"ionic cordova platform add android"**, and it showed the following warning:

[WARN] cordova-res was not found on your PATH. Please install it globally:

       npm i -g cordova-res

[WARN] Cannot generate resources without cordova-res installed.

       Once installed, you can generate resources with the following command:

       ionic cordova resources android --force

And after running npm i -g cordova-res, I am getting above error

Answer 1

I managed to install it doing the following:

Log as root:

su

Then install but use --unsafe-perm flag:

npm i -g cordova-res --unsafe-perm
