我已经安装了Python 3.5，并且正在运行
pip install mysql-python
它给出了如下错误
错误:Microsoft Visual c++ 14.0是必需的(无法找到vcvarsall.bat)
我已经添加了以下行到我的路径
C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;
C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC
我的电脑上安装了64位的Windows 7。
什么解决方案可以减少这个错误，并通过pip正确安装模块。

要解决以下任何错误:
misaka的车轮建造失败 建造misaka失败 需要Microsoft Visual c++ 14.0 无法找到vcvarsall.bat
解决方案是:
Go to Build Tools for Visual Studio 2017 Select free download under Visual Studio Community 2017. This will download the installer. Run the installer. Select what you need under workload tab: a. Under Windows, there are three choices. Only check Desktop development with C++. b. Under Web & Cloud, there are seven choices. Only check Python development (I believe this is optional, but I have done it). In cmd, type pip3 install misaka. Note if you already installed Visual Studio then when you run the installer, you can modify yours (click modify button under Visual Studio Community 2017) and do steps 3 and 4. Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient. (You can also install the Visual Studio Build Tools with only these options, so you don’t need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5 GB, so saving off anything is helpful

安装spaCy模块时也遇到同样的问题。我检查了控制面板，我已经安装了几个Microsoft Visual c++的可重分发版本。
我选择了“Microsoft Visual Studio Community 2015”，它已经安装在我的电脑上→“修改”→勾选“Visual c++ 2015常用工具”。然后需要一些时间和下载超过1gb来安装它。
这解决了我的问题。现在我已经安装了spaCy。

在Stack Overflow上阅读了很多答案后，没有一个可以工作，我最终设法按照这个问题中的步骤解决它。我将把步骤留在这里，以防页面消失:
请尝试安装Visual Studio 2017的构建工具，选择工作负载“Visual c++构建工具”，并检查选项“c++ /CLI支持”和“vc++ 2015.3 v14.00 (v140)桌面工具集”，如下所示。
正如其他回复所指出的，一个解决方案是安装Visual Studio 2015。但是，它会占用几gb的磁盘空间。
一种解决方法是安装预编译的二进制文件。Python扩展包的非官方Windows二进制文件(镜像)网页包含许多Python包的预编译二进制文件。下载您感兴趣的软件包后，您可以使用pip install安装它，例如pip install mysqlclient - 1.3.10 - cp35 - cp35m - win_amd64.whl。
使用这个可以节省时间
pip install pipwin
pipwin install yourLibrary
pipwin类似于pip，但它安装由Christoph Gohlke提供的预编译的Windows二进制文件。节省了你大量的时间搜索和下载。
在这种情况下，pipwin会解决问题
Error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
阅读更多关于pipwin的信息，这里他们提到了Microsoft Visual c++
