错误:找不到模块'jasmine-core'

我安装了以下testing:

"devDependencies": { "jasmine-core": "^2.4.1", "karma": "^0.13.22", "karma-jasmine": "^0.3.7", "karma-phantomjs-launcher": "^1.0.0" } 

运行karma start我得到以下错误:

在这里输入图像描述

做一个search这是同样的问题的第一个问题: 业力开始找不到模块“茉莉花核心”

不过,我已经尝试了两个答案,全球安装jasmine-core ,我已经做了npm install jasmine-core --save-dev 🙁


我的test/index.html

 <!DOCTYPE html> <html lang="en"> <head> <title>Jasmine Spec Runner</title> <link href="testing.css" rel="stylesheet"> <script src="../app/assets/js/libs/vendors.min.js"></script> <script src="../app/assets/js/bundle.js"></script> </head> <body> <div> <header> <h1>Jasmine tests for Dashboard</h1> </header> </div> </body> </html> 

我的karma.conf.js

 // Karma configuration // Generated on Mon Mar 14 2016 11:56:04 GMT-0500 (CDT) module.exports = function(config) { config.set({ // base path that will be used to resolve all patterns (eg. files, exclude) basePath: '.', // frameworks to use // available frameworks: https://npmjs.org/browse/keyword/karma-adapter frameworks: ['jasmine'], // list of files / patterns to load in the browser files: [ 'app/assets/js/bundle.js', 'test/**/*.js' ], // list of files to exclude exclude: [ ], // preprocess matching files before serving them to the browser // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor preprocessors: { }, // test results reporter to use // possible values: 'dots', 'progress' // available reporters: https://npmjs.org/browse/keyword/karma-reporter reporters: ['progress'], // web server port port: 9876, // enable / disable colors in the output (reporters and logs) colors: true, // level of logging // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG logLevel: config.LOG_INFO, // enable / disable watching file and executing tests whenever any file changes autoWatch: false, // start these browsers // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher browsers: ['PhantomJS'], // Continuous Integration mode // if true, Karma captures browsers, runs the tests and exits singleRun: true, // Concurrency level // how many browser should be started simultaneous concurrency: Infinity }) } 

只是猜测,但尝试清洗npmcaching,删除node_modules并重新从头开始重新安装所有的东西:

 $ rm -rf node_modules $ npm cache clean $ npm i $ sudo npm uninstall -g jasmine-core $ sudo npm cache clean -f $ sudo npm i -g jasmine-core 

package.json声明karma时,它会作为本地依赖项安装在项目的node_modules目录中。 但是从控制台karma start运行karma start执行你全局安装的karma 。 所以有两个版本的Karma(本地和全局),都有一个依赖jasmine-core ,需要安装。

当获得在karma start Cannot find module 'jasmine-core' ,那么全球安装的卡玛错过了“茉莉花心”。 所以要确保你在全球范围内安装。 最好是运行以下命令:

 npm install -g karma npm install -g jasmine-core npm install -g karma-jasmine 

之后,你应该可以在有karma.conf.js文件的目录上运行karma start

你也可以使用本地安装的Karma。 所有你需要做的就是这样安装它:

 npm install --save-dev karma npm install --save-dev jasmine-core npm install --save-dev karma-jasmine 

如果你已经这样做了,那么确保你也在node_modules的path中执行它:

 ./node_modules/karma/bin/karma start 

如果你在本地目录下的命令行启动业力,你应该在全球安装karma-cli而不是karma
