Troubleshooting [Errno 2] No such file or directory

[alexpyoung]

My build system was working yesterday before you merged https://github.com/darrenderidder/Sublime-JSLint/pull/21. I updated the User Settings file as instructed and am now receiving the following error:

[Errno 2] No such file or directory
[cmd:  [u'node', u'/Users/Alex/Library/Application Support/Sublime Text 2/Packages/JSLint/linter.js', u'--predef', u"['angular', 'document', '\\$', '_', 'JQuery', 'FB']", u'--sloppy', u'--indent', u'2', u'--node', u'--nomen', u'--vars', u'--plusplus', u'--stupid', u'--todo', u'/Applications/MAMP/htdocs/Project/assets/js/service.js']]
[dir:  /Applications/MAMP/htdocs/Project/assets/js]
[path: /usr/bin:/bin:/usr/sbin:/sbin]
[Finished]

I can still run node from the command line with the 'node'. Any ideas of what's wrong?

[darrenderidder]

What's your operating system and version.

[alexpyoung]

Mac OS X 10.9.2

[darrenderidder]

Does it run when you empty the JSLint User Settings? What version of JSLint does Package Control indicate you have?

[alexpyoung]

Nope, same error.

[darrenderidder]

Tools - Command Pallete - Package Control : List Packages; which version of JSLint?

[alexpyoung]

Couldn't find a version number, but it looks like it was dated 8/26/2013

[darrenderidder]

Run Tools-Command Palette - Package Control: Upgrade Packages

[alexpyoung]

All my packages are currently upgraded

[darrenderidder]

You should have JSLint v.2014.04.03.04.04.35 (under Tools - Command Palette - Package Control: List Packages)...?

[alexpyoung]

Oops. Yes, that is the version I have.

[darrenderidder]

MacOS worked for me so will need to dig deeper. Can you send your settings if they've been modified... will try to reproduce it.

[alexpyoung]

Sublime User Settings?

{
    "color_scheme": "Packages/Color Scheme - Default/Solarized (Light).tmTheme",
    "detect_indentation": true,
    "font_size": 14,
    "ignored_packages":
    [
    ],
    "tab_size": 4,
    "translate_tabs_to_spaces": true,
    "use_tab_stops": true
}

[alexpyoung]

I appreciate you taking time to look into it. Do you accept PayPal donations?

[darrenderidder]

No, Preference - Package Settings - JSLint - Settings - Default and User

[alexpyoung]

Default:

    // an array of options to pass to jslint.
    "options" : [

    // jslint command you want to run as an array of strings.

}

User settings are empty

[darrenderidder]

Both these files exist on your system? /Users/Alex/Library/Application Support/Sublime Text 2/Packages/JSLint/linter.js /Applications/MAMP/htdocs/Project/assets/js/service.js

[alexpyoung]

Yes, the error is not unique to any specific JavaScript file. Any file I try to run JSLint on produces the same error (different file name of course)

[darrenderidder]

From the command line: which node

[alexpyoung]

/usr/local/bin/node

[darrenderidder]

Try copying the default settings to user settings and modify user settings ,"jslint": ["/usr/local/bin/node", "~/Library/Application Support/Sublime Text 2/Packages/JSLint/linter.js"]

[alexpyoung]

After running it with the modified user settings:

module.js:340
    throw err;
          ^
Error: Cannot find module '/Applications/MAMP/htdocs/Project/assets/js/~/Library/Application Support/Sublime Text 2/Packages/JSLint/linter.js'

    at startup (node.js:119:16)

[darrenderidder]

Can you paste the modified user settings?

For the jslint property can you try replacing "~/" with "/Users/Alex/" ?

[alexpyoung]

That fixed the issue! Would you mind quickly explaining your debugging thought process and why this solution solved the problem?

[darrenderidder]

Just reading the error messages and process of elimination mainly. That last error is node complaining about not finding a module; the message seems to indicate a weird shell expansion taking place and substituting the tilde for your current working directory. I don't know if this is an issue for all recent Macs and not sure of long-term solution yet.

[darrenderidder]

http://stackoverflow.com/questions/22700025/zsh-tilde-expands-differently-on-os-x

[alexpyoung]

Hmm, do you think that tilde substitution might also have to do with modifications to my .bashrc or .bash_profile? I might have modified it at some point without fully understanding what I was doing

[darrenderidder]

Possibly. echo ~; echo $HOME; file ~/.bashrc could be informative.

[alexpyoung]

echo ~; echo $HOME; file ~/.bashrc; file ~/.bash_profile:

/Users/Alex
/Users/Alex
/Users/Alex/.bashrc: ASCII English text
/Users/Alex/.bash_profile: ASCII text

[darrenderidder]

Could you beta test this: Replace the JSLint.py script with

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sublime
import sublime_plugin
import re
import os

EXEC_LINT = 'js_lint_exec'
SETTINGS_FILE = 'JSLint.sublime-settings'

class JsLintExecCommand(sublime_plugin.WindowCommand):

    def run(self, files=[]):
        settings = sublime.load_settings(SETTINGS_FILE)
        self.window.run_command('exec', {
            'cmd':
                map(os.path.expanduser, settings.get('jslint', ['node', sublime.packages_path() + '/JSLint/linter.js']))  +
                settings.get('options', []) +
                files,
            'line_regex': settings.get('line_regex', '.*// Line ([0-9]*), Pos ([0-9]*)$'),
            'file_regex': settings.get('file_regex', '(^[^# ]+.*$)')
        })

class JsLintOnSave(sublime_plugin.EventListener):

    def on_post_save(self, view):
        settings = sublime.load_settings(SETTINGS_FILE)
        if settings.get('run_on_save', False) == False:
            return
        if re.search(settings.get('filename_filter'), view.file_name()):
            view.window().run_command(EXEC_LINT, {
                'files': [view.file_name()]
            })

# Support calls to the old API of the JSLint package.

class JslintCommand(sublime_plugin.WindowCommand):

    def run(self):
        self.window.run_command(EXEC_LINT, {
            'files': [self.window.active_view().file_name()]
        })

and revert your user settings to the default.

[darrenderidder]

This may not solve the /usr/local/bin path issue but should fix the tilde expansion.

[alexpyoung]

It seems to be working with the modifications to the Python file and default User Settings

[darrenderidder]

From node Mac OS X package installer:

The installation was completed successfully Node was installed at /usr/local/bin/node npm was installed at /usr/local/bin/npm Make sure that /usr/local/bin is in your $PATH.

To do this in your ~/.bashrc file add this line: export PATH=/usr/local/bin:$PATH

You may want to add current directory's node_modules folder also, then the line would be: export PATH=/usr/local/bin:./node_modules/.bin:$PATH

[alexpyoung]

Will do. Thank you for your time

[darrenderidder]

Updated package should be available shortly via Tools - Command Palette - Package Control : Upgrade Packages. Please upgrade and confirm the fix. Feel free to close if the issue is resolved. Cheers... thanks for helping to troubleshoot this.
