I'm trying to install testrpc using the command 

sudo npm install -g ethereumjs-testrpc

It's failing with the below error message. Can someone please help?

sudo npm install -g ethereumjs-testrpc npm WARN npm npm does not support Node.js v0.10.28 npm WARN npm You should probably upgrade to a newer version of node as we npm WARN npm can't make any promises that npm will work with this version. npm WARN npm You can find the latest version at https://nodejs.org/

/usr/local/lib/node_modules/npm/lib/install.js:298 [this, (next) => { computeMetadata(this.idealTree); next() }], ^ npm ERR! Unexpected token >

npm ERR! A complete log of this run can be found in: npm ERR! /home/kumard/.npm/_logs/2017-06-25T18_34_19_267Z-debug.log

This is happening inspite of having a higher version of node

kumard@kumard-Lenovo-G580:~/.npm/_git-remotes$ node -v
v5.12.0

You are using a very old version of node.

I'd suggest to use Node Version Manager (nvm) to install a more recent version of node.

  • You mean higher than v5.12.0?

  • In your log it says npm does not support Node.js v0.10.28. Perhaps you have two versions installed and there's a conflict betweeen them. Also more recent version of node is 8.1.2, also a benefit of nvm is you do not need to use sudo.
