我有package.json文件，其中提到了以下devDependencies：

{  "name": "tabs-torico",
  "version": "1.0.0",
  "dependencies": {},
  "devDependencies": {
  "grunt": "~0.4.2",

 },

现在当我运行npm install时出现以下错误：

运行npm install会安装package.json中提到的所有依赖项，还是需要分别安装jasmine-core和karma-jasmine？

Answer 1

npm install安装package.json中指定的所有依赖项。您应该在node_modules文件夹中找到它。

Answer 2

这是你的业力版本的问题。在package.json文件中包含以下行而不是当前的业力行。

"karma": "^0.11.14"

另外，重要的是要注意，如果你使用的是karma-chrome-launcher 你需要在你的package.json文件中包含它，因为新版本的karma没有附带它。

所以也包括以下一行。

"karma-chrome-launcher": "^0.1.2"

我希望这能解决你的问题。

由于karma，无法成功运行npm install：未安装任何
