With older NuGet 2 the package sources were searched in order but with NuGet 3 and above they are triedin parallel. So NuGet will the all the sources at the same time, then receive the quickest response, in order to improve search efficiency. In this case, you may get that two logs which "package not found error" and "found in first NuGet source". Although, you get the error "package not found", this error infomation will not eventually appear in the results, unless all the search results are false.如果您不希望NuGet搜索所有来源，您可以禁用您不想要的那个通过在％appdata％\NuGet中配置nugget.config文件进行搜索：If you do not want NuGet search all the sources, you can disable the one you do not want to search by configure the nugget.config file in the %appdata%\NuGet: <disabledPackageSources> <add key="customfeed" value="true" /> </disabledPackageSources> 希望这会有所帮助。Hope this helps. 这篇关于NuGet包尝试在所有已配置的NuGet源中检索的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
