Hey guys,
I hope this isn’t too basic or silly of a question to ask - really looking forward to working with Ember Cli and not sure what’s going on. Im a bit new to node and think there’s something up with my NPM - any ideas? Thanks!

What platform are you running on? Windows, MacOS, Linux? I most cases the `-g` option (for global) requires to run the command with admin rights. So for Linux/MacOS you should run something like `sudo npm install -g ember-cli`. For Windows, make sure your terminal has admin rights too (should be the case by default).

It looks as though there there is a likely a permissions issue and that the node environment environment you have configured is only working with sudo access.
For a lot of subtle reasons you really want to avoid having to use sudo when installing node and node modules.
In general, I would recommend removing node completely from your computer (there are various instructions on how to do this if you google around) and then reinstall node and npm cleanly using only local user permissions. It will make things less complicated and less error prone in the long run.
Once you have removed node…
NVM (Node Version Manager) is a clean way to manage and install node on your Mac and you can easily install multiple versions if needed.
See more here.

The trick is to never use sudo when running node and npm commands, that way you can be assured everything will just work with your regular user permissions and everything will be installed in your regular home directory.
The reason I suggest uninstalling node first is that you will want to avoid conflicts with multiple versions of node in your $PATH and make sure you are always using the version installed with regular user permissions.
I wrote a general write up here if you are new to node and ember cli [Introduction to Ember CLI, Node and NPM · GitHub](https://gist.github.com/eccegordo/ad908734e7798bf6fa86)
Hope it helps

Hey guys - I seem to still be running into some issues getting ember-cli to work. I followed the steps to uninstall node and npm and reinstall. It
```
$ ember
bash: ember: command not found
```
Here’s what I’m getting when I try to install ember
```
$ npm install -g ember-cli
```
Here’s what I’m getting

It appears that perhaps nvm and node weren’t installed correctly.
remove the node in
```
/usr/local/bin/node
```
And then follow the NVM install instructions here: [https://github.com/creationix/nvm/blob/master/README.markdown](https://github.com/creationix/nvm/blob/master/README.markdown)
e.g.
```
curl https://raw.githubusercontent.com/creationix/nvm/v0.24.1/install.sh | bash
```
If that command runs successfully you should have NVM installed and then you can use NVM to download and install node itself. Here is the NVM command to install a specific version of node:
```
nvm install 0.12
```
Once that is done when you run the command
```
which node
```
If should return something like this (depending on which version of node gets installed).
```
/Users/apprentice/.nvm/versions/node/v0.12.2/bin/node
```
