ESLint --fix 不编辑文件

Question

我正在尝试使用 ESLint 整理和修复我的代码。 当我使用我的配置文件运行 ESLint 并且没有修复标志时，它运行良好，这就是它的输出。

eslint-c .eslintrc.json ./src/aura/SearchAvailableNumbers

/home/jason/sfa/testproj/src/aura/SearchAvailableNumbers/SearchAvailableNumbersController.js
    8:9   error  Unexpected blank line after variable declarations  newline-after-var
   15:13  error  'hlp' is defined but never used                    no-unused-vars
   50:30  error  'helper' is defined but never used                 no-unused-vars
   55:32  error  'helper' is defined but never used                 no-unused-vars
   59:42  error  'helper' is defined but never used                 no-unused-vars
   69:7   error  Expected { after 'if' condition                    curly
   69:22  error  Expected '===' and instead saw '=='                eqeqeq
   71:22  error  Expected '===' and instead saw '=='                eqeqeq
   76:22  error  Expected '===' and instead saw '=='                eqeqeq
   84:50  error  Object properties must go on a new line            object-property-newline
   89:21  error  Expected '===' and instead saw '=='                eqeqeq
  113:27  error  'appEvent' is already defined                      no-redeclare

/home/jason/sfa/testproj/src/aura/SearchAvailableNumbers/SearchAvailableNumbersHelper.js
  14:17  error  Gratuitous parentheses around expression  no-extra-parens
  23:17  error  'appEvent' is defined but never used      no-unused-vars
  24:28  error  Expected '===' and instead saw '=='       eqeqeq
  28:28  error  Expected '===' and instead saw '=='       eqeqeq
  32:28  error  Expected '===' and instead saw '=='       eqeqeq

所有这些信息都是正确的，并且是必须在代码中修复的问题。 所以我再次运行它，这次是

eslint --fix --debug -c .eslintrc.json ./src/aura/SearchAvailableNumbers

现在输出是

✖ 17 problems (17 errors, 0 warnings)

当我打开实际代码时，没有任何改变。当我再次运行 linter 时，它会输出相同的内容。

它明确表示“生成固定文本”，但随后输出“没有要应用的修复”。我找不到任何关于修复标志如何在线工作的信息，所以我求助于 stackoverflow。提前致谢。

并非所有 ESLint 规则都是可修复的（实际上大多数规则目前还无法修复）。您可以通过在此页面上查找扳手字形来了解哪些规则可以自动修复：http://eslint.org/docs/rules/

您遇到错误的规则目前都不是可自动修复的。有些是因为 ESLint 团队还没有找到它们（比如 newline-after-var），有些是因为它很可能会创建与原始代码中预期的不同的逻辑（比如 eqeqeq），有些是因为不可能找出自动修复它的正确方法（如no-unused-vars 和no-redeclare）
