NPM Start无法正常运行（无法在Mac OS X Yosemite上运行Node）

Question

I'm a Rails guy, but I'm trying to learn a bit of Angular JS. I wanted to go through this tutorial , but I can't even get a node server to start running.

Below is the npm-debug.log file

0 info it worked if it ends with ok
1 verbose cli [ 'node', '/usr/local/bin/npm', 'start' ]
2 info using npm@2.7.4
3 info using node@v0.12.2
4 verbose config Skipping project config: /Users/piratetone/.npmrc. (matches userconfig)
5 verbose stack Error: ENOENT, open '/Users/piratetone/package.json'
5 verbose stack     at Error (native)
6 verbose cwd /Users/piratetone/js_projects
7 error Darwin 14.1.0
8 error argv "node" "/usr/local/bin/npm" "start"
9 error node v0.12.2
10 error npm  v2.7.4
11 error path /Users/piratetone/package.json
12 error code ENOENT
13 error errno -2
14 error enoent ENOENT, open '/Users/piratetone/package.json'
14 error enoent This is most likely not a problem with npm itself
14 error enoent and is related to npm not being able to find a file.
15 verbose exit [ -2, true ]

Answer 1

Found the answer in this tutorial here. Also, after getting everything completed there, I also needed sudo to install.

sudo npm start
