我收到此错误；
16 07 2015 13:03:52.741:WARN [preprocess]: Can not load "webpack"!
Error: Can not resolve circular dependency! (Resolving: preprocessor:webpack -> webpackPlugin -> preprocessor:webpack)
我的 karma.conf 看起来像；
var webpack = require('webpack');
module.exports = function (config) {
config.set({
browsers: [ 'Chrome' ], //run in Chrome
singleRun: true, //just run once by default
frameworks: [ 'mocha' ], //use the mocha test framework
files: [
'tests.webpack.js' //just load this file
],
preprocessors: {
'tests.webpack.js': [ 'webpack', 'sourcemap' ] //preprocess with webpack and our sourcemap loader
},
reporters: [ 'dots' ], //report results in this format
webpack: { //kind of a copy of your webpack config
devtool: 'inline-source-map', //just do inline source maps instead of the default
module: {
loaders: [
{ test: /\.js$/, loader: 'babel-loader' }
]
}
},
webpackServer: {
noInfo: true //please don't spam the console when running in karma!
}
});
};
和 tests.webpack.js
var context = require.context('./src', true, /-test\.js$/); //make sure you have your directory and regex test set correctly!
context.keys().forEach(context);
我确实安装了 karma 和 karma-webpack。
有任何想法吗 ？
