jest.config.js 失败 - 意外标记“.” 在 module.exports 中

Question

我一定错过了一些东西，但我正在努力理解这个错误。怎能.出乎意料呢module.exports={}？请指出我正确的方向。谢谢！\jest.config.js:16    module.exports = {          ^SyntaxError: Unexpected token '.'    at wrapSafe (internal/modules/cjs/loader.js:979:16)    at Module._compile (internal/modules/cjs/loader.js:1027:27)    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1092:10)    at Module.load (internal/modules/cjs/loader.js:928:32)    at Function.Module._load (internal/modules/cjs/loader.js:769:14)    at Module.require (internal/modules/cjs/loader.js:952:19)    at require (internal/modules/cjs/helpers.js:88:18)    at readConfigFileAndSetRootDir (...\node_modules\jest-config\build\readConfigFileAndSetRootDir.js:119:22)    at readConfig (...\node_modules\jest-config\build\index.js:217:65)    at readConfigs (...\node_modules\jest-config\build\index.js:406:32)npm ERR!

您module.exports在底部的对象中嵌入了额外的内容。看起来文件应该是：

module.exports = {

    transform: {

        "^.+\\.[jt]sx?$": "<rootDir>/jest-preprocess.js",

    },

    moduleNameMapper: {

        ".+\\.(css|styl|less|sass|scss)$": `identity-obj-proxy`,

        ".+\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": `<rootDir>/__mocks__/file-mock.js`,

    },

    testPathIgnorePatterns: [`node_modules`, `\\.cache`, `<rootDir>.*/public`],

    transformIgnorePatterns: [`node_modules/(?!(gatsby)/)`],

    globals: {

        __PATH_PREFIX__: ``,

    },

    testURL: `http://localhost`,

    setupFiles: [`<rootDir>/loadershim.js`],

    setupFilesAfterEnv: ["<rootDir>/setup-test-env.js"],  

};
