Can this be mentioned on the main page please? It did my head in thinking there was a problem with my npm.

1. Lightning Charge should be compatible with nodejs >= 7.6, can you share the errors you had with node 7 and 10?

2. Using --unsafe-perm should definitely not be needed. This depends on how your environment is setup exactly, but you would usually either install global npm packages with sudo, or configure your npm to install packages to your home dir (which will make sudo unnecessary).

3. I think this was because you switched nodejs versions in between, this should not be required normally.

@K3TAN25 What is the issue that you ran into exactly?

Note I haven't tried the instructions set out here, but currently this is error I'm facing. Have not switched nodejs versions.

Note to get this error I'm running sudo -i AND sudo infront of the command.
I get permission denied errors when I run as normal user with sudo. Permission denied errors as just root as well.
Any help would be appreciated.

Disregard, I got it working with "configure your npm to install packages to your home dir" link you cited.

Great! I also added this suggestion to the readme in f6cd79a

I would highly recommend learning and using Docker with lightningcharge which would eliminate the risk of compatibility problems.
