"/usr/bin/env: node --harmony: No such file or directory" error on Ubuntu 15.10

Hi,

I've installed redux-cli with:
sudo npm -g install redux-cli
And I get the following error:
`/usr/bin/env: node --harmony: No such file or directory

Env:

:~/sandbox$ node -v
v5.7.0
:~/sandbox$ npm -v
3.6.0

Looks like there is a problem with bang sign, here is a link with similar error:
azproduction/node-mc#3

Thanks Alex

I have the same problem.

Env: same node and npm as OP, Ubuntu 14.04 LTS.

Will try to get to it over the weekend

See here for potential solution

As pointed out in #39 the problem is that Linux kernel does not support multiple arguments in shebangs, so you can't pass the --harmony flag using
#!/usr/bin/env node --harmony

Naive solution to this problem would be to not use env but directly call
#!/usr/bin/node --harmony

But that creates another problem, as the node might be installed somewhere else.

I found this hack for passing arguments to shebang.
But there is already a wrapper on github made exactly for this use case, so you might just want to use this one:

There is a question though, if you should even bother to use --harmony flag, as most of the ES6 features are already active in Node without need for any flags.

The only features --harmony activates are now:
Symbol.toStringTag, Array.prototype.includes and Rest Parameters (see here)

I'm not familiar enough with node to understand all of the nuances of this. I"m running fine on Ubuntu 16.04 with just #!/usr/bin/env node

I'm closing this for now.
