Karma-jasmine沒有安裝

我是Unit Testing的新用戶，因此我今天只需瞭解Jasmine和Karma。Karma-jasmine沒有安裝

我安裝噶：

npm init 
npm install karma --save-dev 
npm install -g karma-cli 
npm install karma-jasmine --save-dev 
npm install karma-chrome-launcher --save-dev 
karma init

然而，當我嘗試推出因緣開始karma.conf.js它將引發我一個錯誤：

Error: Cannot find module 'jasmine-core'

    at Function.require.resolve (module.js:389:19)

    at /usr/local/lib/node_modules/karma-cli/node_modules/resolve/lib/async.js:153:39

我試圖在全球範圍內安裝核心：

npm install -g jasmine-core

但這並沒有解決它。

當我嘗試安裝我得到一個錯誤說：

[email protected] requires a peer of [email protected]* but none was installed.

Note: Since karma-jasmine 0.3.0 the jasmine library is no longer bundled with karma-jasmine and you have to install it on your own. You can simply do it by:

npm install jasmine-core --save-dev

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

確實做到了！謝謝。雖然我在'node-modules'文件夾中沒有看到「karma-jasmine」或「karma-chrome」文件夾，這是否正常？我現在看到'jasmine-core'文件夾和'karma start karma.conf.js'works – Greg

這取決於npm如何解決依賴關係，但這可能是正常的，是的。 '''npm''' [doc]（https://docs.npmjs.com/cli/help） –

的問題是業力在全球範圍內運行。

我的解決方案（最簡單和無痛至少對我來說）是用npm腳本test命令包裝karma start命令，以便任何命令都在本地環境中運行。

package.json，在"scripts": {}中加"test": "karma start"。

"scripts": { "test": "karma start", [...] },
