Visual Studio 2013 error MS8020 Build tools v140 cannot be found
提问by Nectar Zuzi
I had previously been using VS2013 express without issue, but suddenly it began crashing whenever I tried edit the code while it ran existing code fine.
我以前一直在使用 VS2013 express 没有问题，但是每当我尝试编辑代码时它突然开始崩溃，同时它运行现有代码。
I tried uninstalling and switching over to VS2015, but it was crashing as well and wasn't compatible with some of my code. So I uninstalled VS2015 and reinstalled VS2013.
我尝试卸载并切换到 VS2015，但它也崩溃了并且与我的某些代码不兼容。所以我卸载了VS2015并重新安装了VS2013。
The new issue is whenever I try to build a solution it gives the error "MS8020".
新问题是每当我尝试构建解决方案时，它都会出现错误“MS8020”。
The full error message is seen below

That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.
这是 VS2015 的平台工具集。您卸载了它，因此它不再可用。
To change your Platform Toolset:
要更改您的平台工具集：
- Right click your project, go to Properties.
- Under Configuration Properties, go to General.
- Change your Platform Toolset to one of the available ones.
- 右键单击您的项目，转到属性。
- 在配置属性下，转到常规。
- 将您的平台工具集更改为可用工具集之一。

@bku_drytt's solution didn't do it for me.
@bku_drytt 的解决方案对我不起作用。
I solved it by additionally changing every occurence of 14.0to 12.0and v140to v120manually in the .vcxproj files.
我通过在 .vcxproj 文件中手动更改14.0to12.0和v140to 的每次出现来解决它v120。
Then it compiled!
然后就编译了！
