Bower 安装 arcgis-js-api 失败（无法为 dojo 找到合适的版本）

Question

我在尝试运行以下命令时遇到以下错误：bower install arcgis-js-api

我试过安装到一个新目录，也试过在创建基础 bower.json 文件后安装。在网上搜索发现有人遇到这个问题，但没有发布解决方案。

{  
    "name": "arcgis-js-api-sample-app",  
    "version": "1.0.0",  
    "license": "Apache-2.0",  
    "dependencies": {  
        "esri": "arcgis-js-api#3.15.0"  
    },  
    "resolutions": {  
        "dojo": "v1.10.4/esri-3.14.0"  
    }  
}

错误信息： bower install arcgis-js-api ECONFLICT 无法找到适合 dojo 的版本

我无法重现这个问题。如果我只 bower install arcgis-js-api 我可以选择我的分辨率。如果我使用你发布的 bower.json，我会收到警告，但没有错误。

Please note that, esri#3.15.0 depends on dojo#v1.10.4/esri-3.14.0 which resolved to dojo#v1.10.4/esri-3.14.0 dstore#1.1.0 depends on dojo#>=1.8.1 which resolved to dojo#1.12.2 Resort to using dojo#v1.10.4/esri-3.14.0 which resolved to dojo#v1.10.4/esri-3.14.0 Code incompatibilities may occur.

没关系，Bower 只是警告大家注意安全。

你试过了吗bower cache clean？

Answer 2

我找到了解决办法。使用 gitBash 接口时，这似乎是 windows 机器上的一个问题。 gitBash 不允许用户交互响应 selecting 特定版本的依赖项的提示，并且只显示错误消息。

我改用 gitCMD 提示而不是 gitBash。一旦切换到 gitCMD 和运行相同的 bower install arcgis-js-api 命令，关于 selecting 依赖项的问题出现了，我能够成功 select 它们并完成安装。

我希望这对在 windows 上使用 Bower 的其他人有所帮助。
