Can't run on command line in Windows/Cygwin

[davidmichaelkarr]

I'd just like to experiment with Tern, and AngularJS customizations. I'm on Win7/Cygwin. I put the "tern/bin" directory in my path, then ran "tern" from a new shell.

I get the following:

module.js:340
throw err;
^
Error: Cannot find module 'C:\c\users\myuid\git\tern\bin\tern'
at Function.Module._resolveFilename (module.js:338:15)
at Function.Module._load (module.js:280:25)
at Function.Module.runMain (module.js:497:10)
at startup (node.js:119:16)

at node.js:902:3

That translation to "C:\c\users..." is wrong.

Note that if I instead try a more complex command line like this:

node "$(cygpath -m ~/git/tern/bin/tern)"

(If you don't know, "cygpath -m" translates a Cygwin path to a form like "C:/users/...".)

When I run this, I instead get the following:

module.js:340
throw err;
^
Error: Cannot find module 'acorn/acorn'

I have no recent experience with cygwin, but this seems like a fundamental misunderstanding between that environment and node. The failure is in basic module loading, which is not Tern-specific at all. I assume you get the same issues when running other node scripts that require other modules. Did you try? If so, I suspect reporting this to the node (or even cygwin) projects is more productive.

[davidmichaelkarr]

I use this same Node installation to run Karma for javascript unit tests, both on the command line, and from a Maven build script, both from a Cygwin shell.

[marijnh]

Interesting. Still, the module is there, obviously (the file exists, and is a JavaScript program), so something is going wrong when resolving the path to the script — and there Tern doesn't do anything non-obvious... it just calls require with a relative path.

@davidmichaelkarr For node scripts on Cygwin, I exclusively call them like cmd /c tern. Elimininates most issues, and I'd advice to alias it if it works for you.
