在办公室代理上网，在线下载安装了VS2015。结果如下面这两位倒霉哥们所述：
例子一：
Iinstalled Visual Studio 2015 on Windows 10 64bit. I installed Python Toolsduring the installation process. When I first opened Visual Studio the templatefor Python was there. But on restart it was gone.... Python Environments isalso gone. I think that entire Python Tools has gone missing. I reinstalledVisual Studio and the problem happened again. I installed it on anothercomputer with Windows 7 64bit... And it has the same problem. Python templatejust disappears on second launch of application.
就是安装完第一次跑这样子：
第二次跑就变成这样子（python等模板没了）：

还有这位老兄也是：
RecentlyI have downloaded Visual Studio Community 2015 and I wanted to create a newproject using python, but when the dialogue box is displayed I can't find thePython templates. I browse them on installed templates and says that the itemsare not found. When I downloaded Visual Studio I clicked on Custom setup andselected all the options and python tools were among them so its supossed thatI already have them. I can display the python environment in the start page butas I have said before, I can't create a project using a Python template. Pleasehelp me.
然后修改勾选的功能，修复，重装PTVS2.2均不能解决。要了亲命！
最后还是解决了：

就是这样：
好啦：
这个问题比较罕见，发在这里以供后人百度。

后来，我了解到以上这些都是瞎折腾。
因为有人告诉我：VS2015打开方式错了，打开图标上不带B的试试。
这才是真相！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！
我不小心打开了
正确的
图标，所以解决了。

为什么会出现这个错误？
因为Windows10这个坑货把这个东西放前面！！！！

不要闹好吗？我是真的无法更新python！！

4楼是正解

不需要搭建环境吗？

那应该怎么解决
