jest.config.js 失败 - 意外的标记“。” 在 module.exports 中

Question

I must be missing something but I'm struggling to understand this error.

How can . be unexpected in module.exports={} ?

Please point me in the right direction. Thanks!

\jest.config.js:16
    module.exports = {
          ^

jest.config.js :

    },
    testPathIgnorePatterns: [`node_modules`, `\\.cache`, `<rootDir>.*/public`],
    transformIgnorePatterns: [`node_modules/(?!(gatsby)/)`],
    globals: {

    module.exports = {

};

You have an extra module.exports embedded in the object at the bottom. looks like the file should be:

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"],  
};
