Object.keys调用非对象

Question

我是个新手，试着玩它。当我尝试使用gulp-jscs时，我会得到这个错误

'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 Gulp.Orchestrator._runStep (/home/kbadr/Node_Projects/demo/membership/node_modules/gulp/node_modules/orchestrator/index.js:214:10

这是我的gulpfile

var gulp = require('gulp');
var jscs = require('gulp-jscs');

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

Answer 1

如果jscs没有读取访问您的.jscsrc的权限，或者不存在jscs，就会发生这种情况。这发生在我从一个旧的git复制品上复制和粘贴它之后。若要修复此问题，请使用文本编辑器打开文件并将其重新保存，接受要覆盖的提示以及以“.”开头的提示。(例如.jscsrc)再运行你的任务，它就会完成。

我也遇到了同样的问题：“无法在/Desktop/node/My_Project_Name/.jscsrc意外的输入端加载JSCS配置文件.”

通过首先检查文件是否存在于我的项目的根中，我就能够解决这个问题。在终端中运行以下命令：ls -ld .?*

该文件从未为我创建过，所以我创建了.jscsrc文件，然后添加了以下代码：

{
 "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
}

将此文件保存到项目的根目录，然后再次运行gulp任务命令，它应该可以工作。

更新了bower.json中对ngCordova的依赖并解决了这个问题！
