检索 *** 的包元数据时出错 [英] An error occurred while retrieving package metadata for ***

问题描述

这已经被问过很多次了.解决方案(对我有用)是从 packages.config 文件(这就足够了)和 packages 文件夹中删除 *** 包.

This has been asked many times before. The solution (which works for me) is to delete the *** package(s) from the packages.config file (this is enough), and from the packages folder.

这对我来说是一个糟糕的解决方案，因为每次我想安装一些 nuget 包时都必须重复它.罪魁祸首包各不相同，但每次往往都是相同的包(Newtonsoft.Json/NETStandard.Library 等)，直到我删除所有包并尝试重新安装它们(这有时会改变罪魁祸首包).

This is a bad solution for me because it has to be repeated every time I want to install some nuget package. The culprit package varies, but it tends to be the same package(s) every time (Newtonsoft.Json/NETStandard.Library etc...), until I delete all packages and try to reinstall them (this sometimes changes the culprit package).

有解决办法吗?不得不一直做这个手动修复是很伤脑筋的.我认为它指出了我想在我的项目中修改的一些主要潜在问题.

Is there a solution for this? It is nerve-wrecking to have to do this manual fix all the time. And I think it points to some major underlying problem that I would like to amend in my project.
