I also tried it via sudo electronize start but it was the same...

Hey @mika76, where did you install node & npm from? Did you use homebrew? I am concerned that maybe you have somewhere in your chain used sudo to install (maybe node/npm, maybe nvm or some version manager).

Additionally, based on this particular error, it looks like it is the dotnet-generated folders that have permissions problems. EACCES error came from obj/Host/node_modules, so either the permissions are messed up on node_modules dir, or one of the ones up the chain.

You should be able to use ls -lash on those folders and see what the actual permissions are, vs. what they should be. Maybe you will see one of them has root instead of your your username?

Hey @netpoetica, thanks for taking a look.

You're right, all the folders in obj/Host/node_modules are owned by root. As for npm, I honestly don't remember - it might have been through brew.

How can I fix this? re-install node and npm manually or something?

doing a brew info npm results in

It is possible that you installed homebrew using sudo, which then causes you to need to use sudo when brew installing, at which point npm thinks you're a root user or something.

In this particular case, you can just chown -R those directories to your use instead.

In the long run, I recommend uninstalling node & npm completely, maybe uninstalling homebrew even, just making sure that you don't have any of that stuff installed with sudo. You may be able to find some online resources about changing all of these permissions without re-installing, but I personally am worried you might be setting yourself up for many more similar such issues in the future.

Thanks @netpoetica I'll attempt to clean it all up

[mika76]

I guess this issue can be closed also, since it's something on my machine... Thanks for all your help.

[mika76]

Just as an update if anybody hits the same issue a me - I used the following article to uninstall npm and install it using nvm which manages node and npm versions better than things like homebrew: https://ajaykarwal.com/uninstall-node-and-install-nvm/

Works like a dream now...
