我试图使用nopCommerce(这是写在。net核心),但当我想运行项目时,我面临52个错误告诉我运行一个nuget包恢复
Assets文件~\obj\project.assets。Json没有找到。运行NuGet包还原生成此文件。Nop.Web.MVC.Testsote
当我使用右键单击解决方案并选择恢复Nuget包时,我得到这样的消息:
所有的包都已经安装,没有什么要恢复的。
但是这52个错误仍然存在,在工具-> NuGet包管理器->管理解决方案的NuGet包中,解决方案上没有安装任何东西,我最近更新了我的VS2017到15.5.4
If this error occurs as part of a build in Azure DevOps (TFS) and your build already has a NuGet restore task, this error may indicate the NuGet restore task was not able to restore all packages, especially if you use a custom package source (such as an internal NuGet server). Adding /t:Restore;Build to the MSBuild Arguments seems to be one way to resolve the error, but this asks MSBuild to perform an additional NuGet restore operation. I believe this succeeds because MSBuild uses the custom package source configured in Visual Studio. A preferable solution is to fix the NuGet restore task.
为NuGet恢复任务配置一个自定义包源。
创建一个NuGet。列出所有包源(Microsoft Visual Studio Offline Packages, nuget.org和您的自定义包源)的配置文件,并将其添加到源代码控制中。
在Nuget还原任务下的Feeds to use:在我的Nuget .config中选择Feeds选项。
提供NuGet.config的路径。
从MSBuild任务中移除/t:Restore;Build选项。
更多信息可以在这里找到。
我没有在任何地方发现微软建议的删除“packages”文件夹的方法。
来源:解决包恢复错误
You may encounter build errors due to missing files, with a message saying to use NuGet restore to download them. However, running a restore might say, "All packages are already installed and there is nothing to restore." In this case, delete the packages folder (when using packages.config) or the obj/project.assets.json file (when using PackageReference) and run restore again. If the error still persists, use nuget locals all -clear or dotnet nuget locals all --clear from the command line to clear the global-packages and cache folders as described on Managing the global packages and cache folders.
