Install Swagger on Ubuntu

Install npm

$ sudo apt-get install npm

$ sudo npm install npm –g  // upgrade npm to latest version

You may encounter the following error:

/usr/bin/env: node: No such file or directory

This is often a misnaming error, if you install from a package manager you bin may be called nodejs, so you just need to symlink it like so:

$ sudo ln -s /usr/bin/nodejs /usr/bin/node

Install Swagger

git clone https://github.com/swagger-api/swagger-editor.git
cd swagger-editor
npm start

If Swagger is started successfully, you can connect web server on http://localhost:8080.
