自定义 eslint 规则在我们的项目中运行正常,但我不知道如何为它运行测试。我的猜测是我运行了错误版本的 ecmascript,我需要使用 babel 或调整 eslintrc.json 中的某些内容以使其与 mocha 脚本一起使用。
收到错误信息:
AssertionError [ERR_ASSERTION]: A fatal parsing error occurred: Parsing error: The keyword 'import' is reserved

var ruleTester = new RuleTester();
ruleTester.run("no-full-lodash-import", rule, {
valid: [
{code: "import os from \"os\";\nimport fs from \"fs\";" },
{code: "import { merge } from \"lodash-es\";"}
],
invalid: [
{
code: "import _ from 'lodash';",
errors: [{
message: "Fill me in.",
type: "Me too"
}]
}
]
});
我试过的 .jslintrc.json 文件之一:
{
"env": {
"browser": true,
"es6": true,
"mocha": true // add mocha as true to your ".eslintrc. *" file
},
"parserOptions": {
"ecmaVersion": 6,
"sourceType": "module",
"ecmaFeatures": {
"jsx": true
}
},
"rules": {
"semi": "error"
}
}
