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。
当前回答
我也有同样的问题。下载Visual Studio 2017的构建工具对我有用。
其他回答
以下是Windows c++编译器的官方安装指南:

升级setuptools并安装特定的Microsoft Visual c++编译器。
它已经包含了其他答案中提到的一些要点。
确保您已经安装了这些必需的软件包。当我安装检查包时，它在我的情况下完美地工作:
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 Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient.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
使用此链接下载并安装Visual c++ 2015 Build Tools。它将自动下载visualcppbuildtools_full.exe并安装Visual c++ 14.0，而无需实际安装Visual Studio。
安装完成后，重试pip install，您将不会再次得到错误。
我已经在以下平台和版本上进行了测试:
Python 3.6 on Windows 7 64-bit
Python 3.8 on Windows 10 64-bit
我也有同样的问题。更新setuptools的解决方案
pip install -U setuptools
or
pip install setuptools --upgrade
