vue.js - 带有 jest + vuejs + vuetify 的意外标识符

我四处寻找答案。我怀疑这是一个 .babelrc 问题,但我找不到有效的答案。

应用程序运行得很好,但正如我发现的那样,Jest 和 Rollup 都真正依赖于 .babelrc。另一个可能的罪魁祸首是 Leaflet。在我构建和测试的所有组件中,只有包含 Leaflet 和 vue2-leaflet 的组件似乎有这个问题。考虑到我正在开发一款 map 应用,这对我来说至关重要。

我在这里发帖,因为我无法证明任何事情。还有许多其他人也遇到过类似的问题。

终端输出:

我真的很茫然。感谢您的帮助。

最佳答案

默认情况下,Jest doesn't transform anything in node_modules (vuetify 包所在的位置),但您实际上需要它通过配置的 babel-jest 转换运行 vuetify 以便 导入 可以被转译。为此,请在 jest.config.js 中使用此配置:

module.exports = {
transformIgnorePatterns: [
'<rootDir>/node_modules/(?!vuetify)'
],
...
}
