TypeError: 'NoneType' object is unsubscriptable

[jAndy]

Hi,

I've installed the GJsLint on my Debian Lenny 5.0.5 system. Python
version is 2.5.2.

gjslint foobar.js works just fine and displays errors/warnings within
foobar.js, but using

fixjsstyle --strict super.js

throws


Traceback (most recent call last):
File "/usr/bin/fixjsstyle", line 8, in <module>

On more big & complex js files, even "gjslint foobar-complex.js"
throws

Am I doing anything wrong here?

Yup, I'm getting this error too. I'm on Windows, using Python 2.7.

I hit this whenever I use fixjsstyle. I haven't had any problems using
gjslint, though.

I am also getting this error on OS X

Same on Ubuntu 10.04 with Python 2.6.5:

typo error， you can fix in change
/usr/lib/python2.6/site-packages/closure_linter-2.2.1-py2.6.egg/
closure_linter/fixjsstyle.py
change argf to argv at the 36 line

[Andy Perelson]

Thanks for the feedback on these two issues, and the fix suggestion for the problems with fixjsstyle.py. I'll try to get a fixed version of GJsLint out soon, and I can update this thread once that is done.

Thank you,

Andy

I thought I'd just add some more instructions for this. I'm on
Windows, though it should work across other platforms.

When you call easy_install from the command line, add the -Z flag.
This will ensure the Linter is unzipped and you can access the files.
So that's:

Linux:
$ cd /tmp
/tmp$ sudo easy_install -Z http://closure-linter.googlecode.com/files/closure_linter-latest.tar.gz

OS X:
$ sudo easy_install -Z http://closure-linter.googlecode.com/files/closure_linter-latest.tar.gz

Windows:
> easy_install -Z http://closure-linter.googlecode.com/files/closure_linter-latest.tar.gz

That should then create a directory in your site-packages directory
called closure_linter... (Followed by a version number & a Python
version).egg, and you can follow leeight's instructions to fix the
bug.

Even with Closure-linter v2.2.1 I've got this 2 errors:

I always got this bug with "fixjsstyle" -> "

Did you apply the fix that leeight posted? There hasn't been an
official release from Google, so 2.2.1 without the fix will still
reproduce the error.

The fix proposed here is just a temporary thing until Andy releases
the fixed version.

[FGRibreau]

There is no "site-packages" folder in my "/usr/lib/python2.6/" dir.
And I can't find any file named "closure_linter********.egg" (using
spotlight & $find / -name closure)

I've MacOS 10.6.4 with Python 2.5 & 2.6 installed.

try /usr/local/lib/python2.6/dist-packages/closure_linter-2.2.1-py2.6.egg

I've updated GJsLint to version 2.2.4, hopefully both the issues raised in this thread are fixed for everyone.

Thanks,

Andy
