installation problem on Mac OS

[willwangcc]

I can use my node globally, but I don't know why there a message about "node: command not found"

Below is what I do:
`~ git:master ❯ sudo npm install -g ijavascript ✹ ✭

The command sudo npm install -g ijavascript installs IJavascript globally (for all the users in your computer). This requires that node is also installed globally.

If you want to install IJavascript only for your user, see the instructions here.

---

To confirm that node isn't accessible by your root user, please, run the following command:

$ sudo which node || echo Not found
Not found

[willwangcc]

I tried the command and it showed that I can use node globally.

$ sudo which node || echo Not found                     
/usr/local/bin/node

$ ❯ sudo node                                                    
> console.log("Hello")
Hello
undefined

Thanks, @n-riesco， It works. I think that it is not about 'node'.
I do as http://n-riesco.github.io/ijavascript/doc/install.md.html#local-installation shows.
I missed one command conda install nodejs.

Before: I did as Gihub Installation asked.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install pkg-config node zeromq
sudo easy_install pip
sudo pip install --upgrade pyzmq jupyter
sudo npm install -g ijavascript

After: I do as http://n-riesco.github.io/ijavascript/doc/install.md.html#local-installation shows.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install pkg-config node zeromq
sudo easy_install pip
sudo pip install --upgrade pyzmq jupyter
conda install nodejs  
sudo npm install -g ijavascript

[n-riesco]

@WillWang-X Oh... so you've installed Anaconda, haven't you?

I'm happy to hear it's working for you.

I'm going to reopen the issue to remind me to check the installation instructions for mac.

[chrisVillanueva]

I have the same issue as @WillWang-X .
I'm on macHighSierra 10.13.1

I have nodejs and npm installed:

christophers-MacBook-Pro:~ christophervillanueva$ node --version
v9.2.0
christophers-MacBook-Pro:~ christophervillanueva$ npm --version
5.5.1

All installation steps in the README work until the last command;
christophers-MacBook-Pro:~ christophervillanueva$ sudo npm install -g ijavascript

Any suggestions?

[n-riesco]

@chrisVillanueva I've open a new issue to track your problem. See #124

[n-riesco]

Closing this issue since I've opened issue #126 to track any updates needed to the installation instructions on Mac.

[adeelshahid]

since #126 is closed as well, anyone ending up here. Just remove sudo from the above commands and it should fix the problem

pip install --upgrade pyzmq jupyter
npm install -g ijavascript

This is still an issue on OS X High Sierra 10.13.6 today. I had node and npm available to all users but still got errors

Running conda install nodejs fixed the issue. Then npm install -g ijavascript.

@ilonabudapesti Judging by the error message, it looks like you were affected by #165.
