It’s difficult to tell from the pasted output, but it looks like you typed npm install -g spark-cli spark cloud login. It should just be npm install -g spark-cli. If it gives you permission issues (like the EACCES mkdir ...), try sudo npm install -g spark-cli. See if it plays a little friendlier after that. If not, let us know what the latest error output is, and we’ll go from there!
