在MAC OS X中Visual Studio安装失败

Question

首先从https://visualstudio.microsoft.com/vs/mac/下载了Visual Studio安装程序，并开始了下载和安装过程。

在安装过程结束时，出现以下错误。所有事情都以管理员权限运行。

Installation of 'Visual Studio' failed with exception.
MacInstaller.Models.Installer.InstallException: Failed to copy application directory to its destination by NSFileManager. 'path': /private/tmp/dmg.lNyJgV/Visual Studio.app, 'applicationPath': /Applications/Visual Studio.app

就目前而言，我一直在努力奋斗一整天，尝试以不同的组合进行设置。

开发环境

• 操作系统版本：Mojave（10.14.5）
• xCode版本：10.2.1
• Visual Studio for mac v8.5.2（内部版本13）
• .NET Core SDK：3.1.201
• .NET Core运行时：2.1.16

到目前为止一切正常

• 删除了所有部分安装的文件并进行了全新安装。 https://social.msdn.microsoft.com/Forums/en-US/6a94b169-82c3-4ace-8de1-0c090e67a198/cant-install-mac-visual-studio-2019-community?forum=vssetup
• 通过删除不同的组件组合（Android，iOS SDK，.netCore）进行安装

以上都不适合我，任何建议将不胜感激。

Answer 1

为此找到了解决方法。

一旦通过以下屏幕，
1. Visual Studio for Mac 安装程序将下载安装Visual Studio所需的所有组件，这些组件将存储在/Users/user-name/Library/VisualStudioInstaller/downloads中

---

1. 您可以使用快捷方式cmd+shift+g
直接导航到此处

---

1. 然后运行安装并等待失败。 在/Users/user-name/Library/Logs/VisualStudioInstaller中找到日志报告 并且包含所有已通过和失败的步骤。根据失败点，您可以选择要执行的操作。

2. 在日志报告中清楚地读取失败原因。就我而言，问题是使用NSFileManager移动文件，日志文件显示其余组件已正确安装。

因此从第2步中说明的下载目录中手动安装了visualstudioformac-8.5.2.13.dmg。

Answer 2

我遇到了类似的问题。由于macOS在安装时需要复制文件的权限，但是由于某些原因，不会显示弹出窗口，因此复制失败。因此，单击重试，直到出现弹出窗口以键入登录用户的密码。
