Question

我收到以下错误：

Message:
    Unable to find suitable version for underscore
Details:
    code: ECONFLICT
    picks: [object Object],[object Object],[object Object]

使用以下bower文件，此错误我以前从未遇到过。我不能使用交互式shell，因为它被部署到持续集成。我们也更喜欢使用Github repo链接（不要问我为什么）而不是凉亭包。

{
    "name": "Nightbird",
    "version": "0.0.1",
    "main": "src/css/style.scss",
    "dependencies": {
      "backbone": "git@github.com:jashkenas/backbone.git#1.1.2",
      "underscore": "git@github.com:jashkenas/underscore.git#1.6.0",
      "aisis-bootstrap-theme": "git@github.com:AdamKyle/Aisis-Bootstrap-Theme.git#0.5.0",

      "markdown-js": "git@github.com:evilstreak/markdown-js.git#v0.5.0",
      "to-markdown": "git@github.com:domchristie/to-markdown.git#v0.0.2",
      "font-awesome": "git@github.com:FortAwesome/Font-Awesome.git#4.2.0",
      "react-bower": "git@github.com:reactjs/react-bower.git#0.11.1",
      "showdown": "git@github.com:coreyti/showdown.git#0.3.1",
      "pure": "git@github.com:yahoo/pure.git#0.5.0"
    }
}

有什么想法吗？这是一个错误吗？或只是开发人员愚蠢？

3个不同版本的下划线之间存在冲突这样做的原因是3个依赖项需要下划线：Nightbird，backbone和underscore.inflection。
使用最新版本的Bower，您可以看到以下信息：

Unable to find a suitable version for underscore, please choose one:
    1) underscore#1.6.0 which resolved to 1.6.0 and is required by Nightbird
    2) underscore#>=1.5.0 which resolved to 1.6.0 and is required by backbone#1.1.2
    3) underscore#~1.7.0 which resolved to 1.7.0 and is required by underscore.inflection#1.2.0

您可以通过将以下内容添加到bower.json来强制bower使用特定版本以解决问题。在这个例子中，它将强制使用1.6.0：

"resolutions": {
  "underscore": "1.6.0"
}

无法为下划线找到合适的版本
