Json 由于因果报应，无法成功运行npm安装：未安装

我有一个package.json文件，其中提到了以下devdependency：

{  "name": "tabs-torico",
  "version": "1.0.0",
  "dependencies": {},
  "devDependencies": {
  "grunt": "~0.4.2",
"grunt-angular-templates": "~0.5.1",
"grunt-autoprefixer": "~0.4.0",

 },
 "engines": {
"node": ">=0.8.0"
},
 "scripts": {
   "test": "grunt test"
}
}

现在，当我运行npm安装时，会出现以下错误：

npm WARN optional SKIPPING OPTIONAL DEPENDENCY:

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

npm install会安装package.json中指定的所有依赖项。您应该在节点模块文件夹中找到。

这是您的karma版本的问题。 在package.json文件中，包含以下行，而不是当前的karma行

"karma": "^0.11.14"

另外，需要注意的是，如果您使用的是karma chrome launcher 您还需要将其包含在package.json文件中，因为新版本的karma没有随附

因此，也包括以下几行

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

我希望这能解决你的问题
