Issue Installing Node and Yarn (Mac OS) - Posting here in case others get stuck

[trevoraaron]

I ran into an issue when attempting to install Node and Yarn at the 4hr 19 minute mark.

Issue encountered: When trying to install Yarn after installing Node (directly from the website, using the installer, as the class instructed) I encountered 'Error: EACCES: permission denied, access '/usr/local/lib/node_modules'

Resolution: After reading posts on Stack Overflow, I found this post here. I looked into the answers, and one referenced the npm Docs(link), saying npm themselves recommend not using the installer to install node. Instead, they recommend using node version manager (nvm).

I followed the steps in that answer Install nvm via curl curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

If you are running into errors with that, like I was, I recommend installing Xcode for Mac. I read more information here (link) Essentially you can download the entire Xcode app from Apples App Store, or via the Mac terminal, you can type xcode-select --install It will take quite a while to install, but once that is done, exit out of your terminal and open it back up, then run the following to see if it worked: command -v nvm Result should return nvm

After all that, you should be able to finally run nvm install node

That should be it, you can now run and install yarn npm install --global yarn

Hopefully if anyone else is running into this issue they come here and find this helpful. I may also write up a Q and A post in Stack Overflow.

FYI if you followed the steps above, you'll have to use npm to install ganache-cli as well I ran the below and it works so far. npm install --global ganache-cli

Another FYI (sorry for the spam): For some reason version 17 of Node does not work well with ganache-cli I downgraded node to version 16 and ganache-cli seemed to work just fine To downgrade nvm install v16.13.1
