Question

我的component.json文件：

{
  "name": "my-project",
  "version": "1.0.0",
  "main": "path/to/main.css",
  "dependencies": {
    "jquery": null
  }
}

我跑的时候 $ bower install

我明白了：

bower error无法调用null的方法'split'

Stack trace:

null不是依赖项的有效值。您必须指定一个版本。

"dependencies": {
  "jquery": "1.10.2"
}

指定semver Range：

可以是近似值

"jquery": "~1.10"

"jquery": "1.10.x"

或者，它可以设置为"latest"，目前将安装2.0.3：

"jquery": "latest"

bower安装最终会出现错误：无法调用null的方法'split'
