probably need to be on a much more recent version of node.

[Lalitpatadiya12]

@paOol But in document it self mentioned the require version that's why i have installed. so what should i do if you have idea, please suggest me.

[knoxcard]

Just use the latest version of node. Can't really go wrong with that I am thinking. At time of writing this, latest version is 9.4, there were problems with NPM recently in versions 9.0 to 9.2, but all has been resolved with the latest.
