无法安装visual studio 2017 localdb

Question

我安装了Visual Studio Enterprise 2017

使用它的安装程序，我检查了Data Storage and processing

以及来自各个组件的Sql Server Express 2016

因此，我可以在我的C#应用程序中访问C#，但是当installer/modifer完成时，会出现一个错误：

Setup completed with warnings -> Couldn't install sqllocaldb

在日志文件中我发现：

Package 'sqllocaldb,version=15.1.61710.120,chip=x64,language=en-US' failed to install.

。

    The installer has encountered an unexpected error
 The error code is 2349. Copy resumed with different info.

全日志：

Something went wrong with the install.

You can troubleshoot the package failures by:

    1. Search for solutions using the search URL below for each package failure
    2. Modify your selections for the affected workloads or components and then retry the installation
    3. Remove the product from your machine and then install again

If the issue has already been reported on the Developer Community, you can find solutions or workarounds there. If the issue has not been reported, we encourage you to create a new issue so that other developers will be able to find solutions or workarounds. You can create a new issue from within the Visual Studio Installer in the upper-right hand corner using the "Provide feedback" button.
