Error in installing truffle in macOS

Question

I am facing some issue in the installation of truffle. I used the command

 sudo npm install -g truffle
 /Users/vikas/.nvm/versions/node/v9.11.2/bin/truffle ->
 /Users/vikas/.nvm/versions/node/v9.11.2/lib/node_modules/truffle/build/cli.bundled.js
 truffle@4.1.13 added 81 packages in 14.406

Successfully added the packages but when I run command truffle version

or any another truffle command it gives

 -bash: /usr/local/bin/truffle: No such file or directory.

I am using macOS please someone help me out.

Truffle executable is currently installed in /Users/vikas/.nvm/versions/node/v9.11.2/bin/truffle. For some system or npm reason I ignore, this executable isn't accessible from the PATH

You can either:

- add a symlink to your /usr/local/bin/

$ sudo ln -sf /Users/vikas/.nvm/versions/node/v9.11.2/bin/truffle /usr/local/bin/

- add /Users/vikas/.nvm/versions/node/v9.11.2/bin/ to your path

Edit ~/.bash_profile. There will be a line that says something like PATH=$PATH:$HOME/bin.

Add :/Users/vikas/.nvm/versions/node/v9.11.2/bin/ to the end (be sure you have the colon)
