Gulp -jscs Object.keys called by non-object

Question

I am new to gulp and trying to play with it. I get this error when I try to use gulp-jscs

 'default' errored after 98 ms [16:58:00] TypeError: Object.keys called on non-object at Function.keys (native) at NodeConfiguration.Configuration._throwNonCamelCaseErrorIfNeeded (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp-jscs/node_modules/jscs/lib/config/configuration.js:440:12) at NodeConfiguration.Configuration.load (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp-jscs/node_modules/jscs/lib/config/configuration.js:51:10) at StringChecker.configure (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp-jscs/node_modules/jscs/lib/string-checker.js:66:29) at Checker.configure (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp-jscs/node_modules/jscs/lib/checker.js:26:39) at module.exports (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp-jscs/index.js:31:11) at Gulp.<anonymous> (/home/kbadr/Node_Projects/demo/membership/gulpfile.js:22:15) at module.exports (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp/node_modules/orchestrator/lib/runTask.js:34:7) at Gulp.Orchestrator._runTask (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp/node_modules/orchestrator/index.js:273:3) at Gulp.Orchestrator._runStep (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp/node_modules/orchestrator/index.js:214:10 

and here my gulpfile

 var gulp = require('gulp'); var jscs = require('gulp-jscs'); gulp.task('default', function () { return gulp.src('src/app.js') .pipe(jscs()); });

This happens if jscs does not have read access to your .jscsrc or if it does not exist. This happened to me after copying and pasting it from an old reproduction. To fix this, open the file with a text editor and save it by accepting the overwrite prompt, and also starting with ".". (e.g. .jscsrc) Run your task again and it will complete.

I had the same problem: "Failed to load AOS configuration file in /Desktop/node/My_Project_Name/.jscsrc Unexpected end of input ...."

I managed to solve the problem by first checking if the file exists in the root of my project. run the following command in the terminal: ls -ld.? *

The file was never created for me, so I created the .jscsrc file, then added the following code:

 { "excludeFiles": ["node_modules/**", "bower_components/**"], "requireCurlyBraces": [ "if", "else", "for", "while", "do", "try", "catch" ], "requireOperatorBeforeLineBreak": true, "requireCamelCaseOrUpperCaseIdentifiers": true, "maximumLineLength": { "value": 100, "allowComments": true, "allowRegex": true }, "validateIndentation": 4, "validateQuoteMarks": "'", "disallowMultipleLineStrings": true, "disallowMixedSpacesAndTabs": true, "disallowTrailingWhitespace": true, "disallowSpaceAfterPrefixUnaryOperators": true, "disallowMultipleVarDecl": null, "requireSpaceAfterKeywords": [ "if", "else", "for", "while", "do", "switch", "return", "try", "catch" ], "requireSpaceBeforeBinaryOperators": [ "=", "+=", "-=", "*=", "/=", "%=", "<<=", ">>=", ">>>=", "&=", "|=", "^=", "+=", "+", "-", "*", "/", "%", "<<", ">>", ">>>", "&", "|", "^", "&&", "||", "===", "==", ">=", "<=", "<", ">", "!=", "!==" ], "requireSpaceAfterBinaryOperators": true, "requireSpacesInConditionalExpression": true, "requireSpaceBeforeBlockStatements": true, "requireLineFeedAtFileEnd": true, "disallowSpacesInsideObjectBrackets": "all", "disallowSpacesInsideArrayBrackets": "all", "disallowSpacesInsideParentheses": true, "validateJSDoc": { "checkParamNames": true, "requireParamTypes": true }, "disallowMultipleLineBreaks": true, "disallowCommaBeforeLineBreak": null, "disallowDanglingUnderscores": null, "disallowEmptyBlocks": null, "disallowMultipleLineStrings": null, "disallowTrailingComma": null, "requireCommaBeforeLineBreak": null, "requireDotNotation": null, "requireMultipleVarDecl": null, "requireParenthesesAroundIIFE": true } 

Save this file in the root directory of your project, and then run the gulp task command, it should work.

Updated dependency in bower.json on ngCordova and resolved the issue.
