node -v = v8.9.4

webpack.config.js

var webpack = require('webpack');


module.exports = {
  module: {
    loaders: [
      {exclude: ['node_modules'], loader: 'babel', test: /\.jsx?$/},
      {loader: 'style-loader!css-loader', test: /\.css$/},
      {loader: 'url-loader', test: /\.gif$/},

preprocessor.js

      src = webpackAlias.process(src, filename, ...rest);

我需要一些帮助我已经尝试删除所有节点模块并使用yarn或npm

进行安装提前谢谢卡洛斯维埃拉

我已删除节点模块并将jest升级到22版本和应用纱线安装，但仍然是相同的错误。

Answer 1

从jest issues

复制

我发现了这个问题。我从Jest配置中删除了“js”作为文件扩展名，因为我只有“ts”文件。你不能这样做。再次添加“js”可以解决我的问题。

请尝试在package.json中添加以下行。 "jest": { "moduleFileExtensions": [ "ts", "js" ] }

找不到'jasmine_light.js'中的模块'./create_spy'
