I am performing Nodejs development in emacs, but my environment seems incorrect. For example, when I run ac-js2-jump-to-definition, I get "no jump location found" in the minibuffer. How can I get this working?

Here is a sample of code, where the "jump-to-definition" function works in other environments like WebStorm:

But it does not work when I put the point over someFunction() above and run M-x ac-js2-jump-to-definition. Also, when I run js2-next-error, the require function in require('auth')() above is selected and gives the message "Undeclared variable or function 'require'".

I suspect that my Javascript environment is correct, but my Nodejs environment is not set up. What is wrong with my node environment, and how can I fix it?

I am performing Nodejs development in emacs, but my environment seems incorrect. For example, when I run ac-js2-jump-to-definition, I get "no jump location found" in the minibuffer. Also when I run 'tern-find-definition`, I get "No definition found.".

How can I correctly jump to a Javascript definition in emacs?

Here is a sample of code, where I am using the "jump-to-definition":

But it does not work when I put the point over someFunction() above and run M-x ac-js2-jump-to-definition or tern-find-definition. Also, when I run js2-next-error, the require function in require('auth')() above is selected and gives the message "Undeclared variable or function 'require'".

I suspect that my Javascript environment is incorrect, but I don't know what it is. Any suggestions would be appreciated.
