In the configuration file for your project (e.g. karma.config.js), check if you have the plugins listed
在您项目的配置文件（例如 karma.config.js）中，检查您是否列出了插件
plugins : [
'karma-junit-reporter',
'karma-chrome-launcher',
'karma-firefox-launcher',
'karma-opera-launcher',
'karma-ie-launcher',
'karma-jasmine'
],

You have to install the IE launcher, from your project directory where you have installed karma, install ie launcher:
您必须安装 IE 启动器，从您安装 karma 的项目目录中，安装 IE 启动器：
$ npm install karma-ie-launcher
That should create a karma-ie-launcher folder under node_modules(default karma installation folder). Mind that 'plugins:[]' configuration simply instruct Karma what to load, you still have to install the browser launchers if you have not done so in initial Karma installation.
这应该在 node_modules（默认 karma 安装文件夹）下创建一个 karma-ie-launcher 文件夹。请注意，'plugins:[]' 配置只是指示 Karma 加载什么，如果您在初始 Karma 安装中还没有安装浏览器启动器，您仍然需要安装浏览器启动器。

Amend Package.Json
修改 Package.Json
I had a similar problem with Chrome. After setting the environment variables as you did, what eventually worked was ensuring the following following entries with the specified version numbers in the package.json's devDependencies:
我在 Chrome 上遇到了类似的问题。像您一样设置环境变量后，最终起作用的是确保以下条目在 package.json 的 devDependencies 中具有指定的版本号：
"karma-jasmine": "~0.2.2",
"karma-chrome-launcher": "~0.1.2",
Then perform:
然后执行：
npm update

I'm currently using npm to manage packages and plugins, so I don't know if the steps I followed are the same for you. I see that your question is two years old, I'm currently working on Karma 0.13.15.
我目前正在使用npm来管理包和插件，所以不知道我遵循的步骤是否与您相同。我看到你的问题已经两年了，我目前正在研究 Karma 0.13.15。
Basically to solve this problem I've performed
基本上是为了解决这个问题，我已经执行了
npm install karma-ie-launcher --save-dev -save
This command can be used to download the IE launcher plugin and update karma.config.js.
此命令可用于下载 IE 启动器插件和更新 karma.config.js。

Try wrapping your paths in quotes, e.g.:
尝试将您的路径用引号括起来，例如：
SET IE_BIN="C:\Program Files (86)\Internet Explorer\iexplore.exe"
Also, make sure you've installed and configured Karma IE launcher.
此外，请确保您已安装并配置Karma IE 启动器。
