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 = {

          ^

    },

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

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

    globals: {

        __PATH_PREFIX__: ``,

    },

    testURL: `http://localhost`,

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

    module.exports = {

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

    }

};

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 = {&nbsp; &nbsp; transform: {&nbsp; &nbsp; &nbsp; &nbsp; "^.+\\.[jt]sx?$": "<rootDir>/jest-preprocess.js",&nbsp; &nbsp; },&nbsp; &nbsp; moduleNameMapper: {&nbsp; &nbsp; &nbsp; &nbsp; ".+\\.(css|styl|less|sass|scss)$": `identity-obj-proxy`,&nbsp; &nbsp; &nbsp; &nbsp; ".+\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": `<rootDir>/__mocks__/file-mock.js`,&nbsp; &nbsp; },&nbsp; &nbsp; testPathIgnorePatterns: [`node_modules`, `\\.cache`, `<rootDir>.*/public`],&nbsp; &nbsp; transformIgnorePatterns: [`node_modules/(?!(gatsby)/)`],&nbsp; &nbsp; globals: {&nbsp; &nbsp; &nbsp; &nbsp; __PATH_PREFIX__: ``,&nbsp; &nbsp; },&nbsp; &nbsp; testURL: `http://localhost`,&nbsp; &nbsp; setupFiles: [`<rootDir>/loadershim.js`],&nbsp; &nbsp; setupFilesAfterEnv: ["<rootDir>/setup-test-env.js"],&nbsp;&nbsp;};
