Trouble when installing MEANIO on Mac OS X using npm - node.js

Question

When I try to install MEANIO on my Mac using npm, I encountered several errors which failed the installation. The errors are shown below:
There are two major types of problem: one is Error EACCES, and the other one is ERROR ENOENT. I have attempted several solutions, which don't really help much.
1. sudo npm clear cache
2. sudo npm update -g
3. Permission fix: by changing nodejs folder's permission to local user
(refer to: npm install errors with Error: ENOENT, chmod)
I wonder what is causing the problem. Since I am not publishing my own app, there is no way to include .npmignore according to the solution provided in the link. The second answer in the link claims that the nature of the problem is:
"Above action caused some dependencies being installed inside ~/.npm/ dir, having root:root ownership (because of sudo ...). Evidently npm does not run as local user (or change dependencies subdirs ownership afterwards) when pulling dependencies and writing them to a local user subdir ~/.npm/. As long as npm would be so careless against fundamental unix filesystem security issues the problem would reoccur."
I doubt if this is the correct in my case. The installation of MEANIO shouldn't be causing so many problems.
The shell commands and error messages are shown below:
localhost:local Nick_Guan$ sudo npm install -g meanio#latest

Any help would be appreciated.

Answer 1

double check whether prerequisite is installed rightly, make sure execute the install command in somewhere under your home directory.
Check here: https://groups.google.com/forum/#!topic/gnu.bash.bug/JkcxWDfilZI
You're in a directory which can be read and
searched only by root, and you're su'ing to another user. That user
does not have permission to search the current directory, even to find
`..', so getcwd is going to fail.

Answer 2

I had a similar problem and found the permission issue was on the base npm directory in my root user directory /User/tomk/.npm in my case. The subdirectory for npm was owned by root (probably from having to sudo to install node/npm). Once I changed the ownership to my account, meanio installed without the fatal errors (lots of warnings, but nothing to stop the install).
