I solved the issue !
I had my bash to automatically update node to the latest version, which in my case was the 15.0.1 (which is including the latest futures). However, it causes some problems when trying to install NOT only @apollo/client, but also @material-ui/core, icons and so on…
So, i switched from my current node version to 14.15.0 (Recommended for most users, as nodejs says) using:
nvm install 14
