Question

我尝试在visual studio 2017社区离线安装objc-syntax-highlighting.vsix。我无法重新获得它。我已从https://github.com/Microsoft/WinObjC/releases下载了扩展程序包，并尝试从0.2预览（2017年12月）安装程序包

有谁可以帮我解决这个问题？

Answer 1

您使用了错误的扩展程序。对于Visual Studio 2017，请安装支持VS2015和Visual Studio 2017的objc-language-services-VS2017.vsix。

Answer 2

该软件包只能安装在VS，2015及更早版本中，请向作者索取更新

Answer 3

查看其中包含的日志文件，您在计算机上安装了VS2017社区，我们可以在日志文件的后半部分看到此确认。从日志中间，我们可以看到VS2012和VS2015 community / ultimate / premium / professional / enterprise支持此扩展。因此，您会收到错误消息：

此扩展程序不能安装在任何当前已安装的产品上。

解决方案是仅下载VS2017社区的扩展版本。

但是，如果不能解决问题，there is a solution to a similar issue here。

以上解决方案的要旨是：

事实证明，.visx扩展名只是一个.zip文件。
将扩展名从.visx重命名为.zip
在文件夹中找到名为extension.vsixmanifest的文件，然后在文本编辑器（如记事本）中打开它。
使用Ctrl + F查找Supported Products部分。
添加以下内容：

    <VisualStudio Version="15.0"> <!-- VS2017 -->
       <Edition>Community</Edition>
       <Edition>Ultimate</Edition>
       <Edition>Premium</Edition>
       <Edition>Pro</Edition>
    </VisualStudio>

保存并关闭文件。
将扩展名从.zip重命名为.visx
双击运行。

VSIX安装程序扩展不能安装在任何当前安装的产品上
