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

在vs -2019 vs 16.4.0上添加WinForms Core 3.1项目(从项目模板中)并尝试开箱运行后看到了这一点。清理或重新构建整个解决方案不起作用。

我刚刚重新加载了我的解决方案。即文件/关闭解决方案,然后重新打开并重新构建它就解决了问题。

For me it turned out to be a nuget source credentials problem. I had recently changed my password for accessing a nexus server and visual studio was still using the old password when trying to access a nuget on that server through the windows credential manager. To fix it, I had to delete the entry for those outdated credentials in the credential manager and after, when I did a nuget restore, it prompted me for a password letting me enter the new password, which got saved in the credential manager again. You can access the credential manager from the cmd line using CmdKey.exe.

我遇到过非常奇怪的经历!

我之前用GIT bash和GIT cmd-Line进行了克隆,遇到了上述问题。

后来,我用turtle - git进行了克隆,一切正常。

也许这是一个疯狂的答案,但尝试一次可能会节省你的时间!

前面提到过,但我只是想再次强调在路径中没有任何空间的重要性!这就是我想要的。我警告过你了。

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。
