在 MAC OS X 中安装 Visual Studio 失败

Question

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

在安装过程结束时，出现了以下错误。 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

现在，我一直在努力尝试用不同的组合来设置它。

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 核心 SDK：3.1.201
• .NET 核心运行时：2.1.16

事情到此为止

• 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安装（Android，iOS SDK，.netCore）

以上都不适合我，任何建议将不胜感激。

Answer 1

找到了解决方法。

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

---

2. 您可以使用快捷键cmd+shift+g直接导航到此处

---

3. 然后运行安装并等待失败。 在/Users/user-name/Library/Logs/VisualStudioInstaller找到日志报告，其中包含所有通过和失败的步骤。 取决于失败点，您可以选择要做什么。

4. 清楚地阅读日志报告中的失败原因。 在我的情况下，问题是使用 NSFileManager 移动文件，并且日志文件显示组件的 rest 已正确安装。

因此，从步骤 2 中解释的下载目录手动安装了visualstudioformac-8.5.2.13.dmg 。这对我有用。

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，但由于某些原因未显示弹出窗口，因此无法复制。 因此，单击重试，直到出现一个输入登录用户密码的弹出窗口。

Answer 3

安装Visual Studio 2022 for Mac (Preview)相同问题

在我的情况下，将下载的.dmg安装为sudo并像往常一样通过Finder运行安装程序。

sudo hdiutil attach lalala.dmg

Answer 4

这很奇怪，我遇到了同样的问题，我所做的是每次都点击“重试”按钮，直到弹出 window 要求您输入密码以获得许可。 然后它就不会再失败了......

Answer 5

我实际上发现该应用程序无论如何都在复制到应用程序中，所以只需等待它完成复制，然后弹出密码对话框并单击重试即可。 继续点击重试的问题在于它每次都会创建应用程序的副本
