install issue

[cjyabraham]

when I run npm install -g svg-autocrop I get npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules. So then I used sudo and got this error:

[~/Sites/svg/input]$ sudo npm install -g svg-autocrop
npm WARN deprecated core-js@2.6.10: core-js@<3.0 is no longer maintained and not recommended for usage due to the number of issues. Please, upgrade your dependencies to the actual version of core-js@3.

Any ideas on how to resolve?

FYI, I ended up installing in a directory from a clone of the source code so resolving this issue isn't urgent.
