我想在我的项目中使用 gulp-jscs,所以我根据文档安装了它:

npm install --save-dev gulp-jscs

但是当我尝试运行 gulp 文件时,我收到了这个错误:

TypeError: Cannot convert undefined or null to object
    at Function.keys (native)
    at copyConfiguration (C:\Users\[User]\Desktop\[Project]\
    node_modules\jscs\lib\config\configuration.js:920:12)

此外,还有其他与此相关的错误:

at NodeConfiguration.Configuration.
_processConfig([location-path]\node_modules\jscs\lib\config\configuration.js:459:5)
    at NodeConfiguration.Configuration.load

您需要.jscsrc在项目的根目录中有一个文件。在那里,您可以提供JSCS 的选项以及应遵循的代码样式规则。

以下是项目本身.jscsrc使用node-jscs。您可以使用它来建立您自己的配置。

{
    "preset": "google",
    "fileExtensions": [".js", "jscs"],

    "requireSemicolons": true,
    "requireParenthesesAroundIIFE": true,
    "maximumLineLength": 120,
    "validateLineBreaks": "LF",
    "validateIndentation": 4,
    "disallowTrailingComma": true,
    "disallowUnusedParams": true,

    "disallowSpacesInsideObjectBrackets": null,
    "disallowImplicitTypeConversion": ["string"],

    "safeContextKeyword": "_this",

    "jsDoc": {
        "checkAnnotations": "closurecompiler",
        "checkParamNames": true,
        "requireParamTypes": true,
        "checkRedundantParams": true,
        "checkReturnTypes": true,
        "checkRedundantReturns": true,
        "requireReturnTypes": true,
        "checkTypes": "capitalizedNativeCase",
        "checkRedundantAccess": true,
        "requireNewlineAfterDescription": true
    },

    "excludeFiles": [
        "test/data/**",
        "patterns/*"
    ]
}

请注意,除非您有 a或已明确指定应遵循的规则jscs,否则实际上不会检查任何内容。"preset".jscsrc
