测试套件无法运行在 vue3 中使用 jest 时找不到模块 'vue-template-compiler [英] Test suite failed to run Cannot find module 'vue-template-compiler when using jest in vue3

问题描述

当我尝试使用 jest 运行测试时，我似乎在 vue3 中遇到错误.

I seem to get a error in vue3 when I try to run the tests with jest.

测试套件运行失败找不到模块'vue-template-compiler

这是我尝试运行测试时得到的结果.我知道这个包来自 vue2 并且我得到了@vue/compiler-sfc"已安装，这是 vue3 版本.如果我确实安装了那个 vue-template-compiler 包，我会收到版本不匹配的错误.

This is what I get when I try to run the tests. I know that package is from vue2 and I got "@vue/compiler-sfc" installed which is the vue3 version of this. If I do install that vue-template-compiler package I get the error of version mismatching.

任何已经找到此问题的解决方案的人，或者只是等待他们更新 vue-jest 以使用其他软件包的人.

Anyone that found a solution to this problem yet or is just waiting till they update vue-jest to work with that other package.

这是我的 package.json

推荐答案

通过将我的 jest.config.js 更改为:

Fixed mine by changing my jest.config.js to:

module.exports = {
  preset: '@vue/cli-plugin-unit-jest',
  transform: {
    '^.+\\.vue$': 'vue-jest',
  },
}
