VSIX 安装失败

Question

我在 visual studio 2019 年下载了扩展程序，但在安装时出现错误。

安装日志是这样的：

     WRN: Assembly binding logging is turned OFF.
     To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
     Note: There is some performance penalty associated with assembly bind failure logging.
     To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Answer 1

运行修复您的 Visual Studio 安装。

Answer 2

如果修复不起作用，您可能已经移动了 VS 安装，现在它不会安装任何东西。

这是因为它“可能”在标准目录以外的目录中找到 VS 安装程序。重新安装安装程序本身，然后尝试安装扩展程序或 whatevs

Answer 3

检查你的C盘是否存在该路径。 “Packages”文件夹用于保存VS需要的VS扩展。我将我的移动到 F 驱动器以保存 space。错误消息对我帮助不大。

C:\ProgramData\Microsoft\VisualStudio\Packages
