Because some of the tools are written as a Node.js application, there is a need to install that Node.js and also the package manager of node.js Because I do not want to install the complete application, I downloaded the binary or executable of node.js and placed that in a file. Afterwards I created a script that changes my PATH variable to the location the node.js binary is located. With that script, I can now use node.js as it was installed. But the advantage I encounter here is that I can now place my environment in version control and share it with my colleagues or with our build server.
If there is a need to install something globally, it is just installed in the directory where node.js is located. Simple and we can not have fun with our project.
