jest.config.js失败-意外令牌''在module.exports中

问题描述

我必须缺少一些东西，但我正在努力理解此错误。

.在module.exports={}中怎么出乎意料？

请指出正确的方向。谢谢！

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

jest.config.js：

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`],module.exports = {
        setupFilesAfterEnv: ["<rootDir>/setup-test-env.js"],}
};

解决方法

您在底部的对象中嵌入了一个额外的module.exports。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"],};
