我安装了以下用于测试:
"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 后出现以下错误:
进行搜索这是具有相同问题的第一个问题:karma start Cannot find module 'jasmine-core'
但是我已经尝试了这两个答案，全局安装了 jasmine-core 并且我已经安装了 npm install jasmine-core --save-dev :(

最佳答案
当在 package.json 中声明 karma 时，它会作为本地依赖项安装在项目的 node_modules 目录中。但是从控制台运行 karma start 会执行全局安装的 karma。所以有两个版本的 Karma(本地和全局)并且都依赖于 jasmine-core，需要安装它。
当在 karma start 上获取 Cannot find module 'jasmine-core' 时，全局安装的 Karma 会丢失“jasmine-core”。因此，请确保您在全局范围内也安装了它。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，您应该能够在包含 karma.conf.js 文件的目录中运行 karma start。
您还可以使用本地安装的 Karma。您需要做的就是以这种方式安装它:
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，那么确保你也从 node_modules 中的路径执行它:
./node_modules/karma/bin/karma start
