npm error Syntax error: word unexpected (expecting ")")

Question

I am trying to install the npm package "serialport" to work with Node.js on Ubuntu.

I have Node.js version 4.3.1

And when I try to install using

sudo npm install serialport

I get the following error;

/usr/local/bin/node: 1: /usr/local/bin/node: Syntax error: word unexpected (expecting ")")

Actually I'm not even able to install npm. I have dependencies missing; I'm on Ubuntu 15. How do I install npm?

When I try to install NPM I get the following error:

It's French but basically saying that some dependencies are missing. It doesn't detect that I have nodejs installed.

But when I try to reinstall Node it is telling me that I already have a better version.

I also noticed that I have node and npm in /usr/local/bin but I also have another folder /node-v4.3.1-linux-armv6l/ that contain a /bin with node and npm but also some more folders like /include, /lib ,/share

To install npm:

sudo apt-get update
sudo apt-get install npm

And then I'm pretty sure you should remove that sudo when installing packages:

npm install serialport

@MadeInDreams Do you have a package.json file? Make sure you have that file and first change to the directory containing package.json and then type npm install serialport. If you install it in the wrong directory errors may occour

I know there is already a marked answer, but it didn't help me.

The error says that there is an error code in javascript file, so I tried to execute this javascript with node:

# nodejs /path_where_npm_is_linked/npm-cli.js

and that works! So I think npm command was not being executed with the right program. Maybe the problem is the other executable 'node' which it has no relation with nodejs, or in the link itself (npm is a link to npm-cli.js). Even the enviroment variable NODE_PATH is configured to nodejs.

So I tried to make my own npm command:

add

alias npm='nodejs /opt/node-v6.11.1-linux-ppc64/bin/npm'

to .bashrc (or other terminal configuration file if you are under other distro) or .bash_aliases (they are inside user home folder) Restart the terminal and voilà :D

Edit: some packages won't install even with this modification (like node-sass). So a symbolic link must be done ln -s path_to_nodejs(ex. /usr/bin/nodejs) /usr/bin/node
