Upgrading Node.js to latest version

Question

So, I have Node.js installed and now when I tried to install Mongoosejs I got an error telling me that I don't have the needed version of Node.js (I have v0.4.11 and v0.4.12 is needed).

How can I upgrade to this version? I suppose I just could install it again with the latest version, but I don't want to do it before I'm sure that my project folders in the folder "node" won't be deleted.

Answer 2

If you are looking in linux..

npm update will not work mostly am not sure reason but following steps will help you to resolve issue...

Terminal process to upgrade node 4.x to 6.x.

 $ node -v
 v4.x

Check node path

$ which node
/usr/bin/node

Download latest(6.x) node files from [Download][1]

[1]: https://nodejs.org/dist/v6.9.2/node-v6.9.2-linux-x64.tar.xz and unzip files keep in /opt/node-v6.9.2-linux-x64/.

Now unlink current node and link with latest as following

$ unlink /usr/bin/node
$ ln -s /opt/node-v6.9.2-linux-x64/bin/node node
$ node -v
$ v6.9.2

Answer 4

Open the package.json file of the node.js project and replace the version number specified with * in the dependencies will fetch you the latest version.

Answer 5

Just bundling node and npm updates to latest version into a single command for my ~/.bash_profile:

update-node(){
  sudo n latest;
  sudo npm install -g npm;
  node --version;
}

This assumes you've already installed "n" from Eldar Djafarov's answer. After saving this to your Bash profile, re-open the terminal and just type update-node and enter your sudo password:

λ update-node
