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 Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient.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

我也有同样的问题。我需要一个64位版本的Python，所以我安装了3.5.0(撰写本文时最新的版本)。切换到3.4.3之后，我的所有模块安装都正常了。
Python Windows版本
我在安装pymssql时遇到了类似的情况。
pip试图构建这个包，因为Python 3.6和Windows没有正式的轮子。
我从非官方的Windows二进制for Python扩展包下载了一个非官方的轮子。
特别针对您的情况:MySQL-python
这里和其他地方的解决方案都不适合我。我的64位Windows 10操作系统上安装了一个不兼容的32位版本的mysqlclient，因为我使用的是32位版本的Python。
我不得不卸载我目前的Python 3.7 32位，并重新安装Python 3.7 64位，现在一切都很好。
我在安装mayavi时遇到了这个问题。
我还犯了一个常见错误:在pip安装库时需要Microsoft Visual c++ 14.0。
在浏览了许多网页和这个问题的解决方案后，没有一个可行，我想出了这些步骤(大部分取自以前的解决方案)可以让这个问题起作用。
Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) → Tools for Visual Studio 2017 If you have already installed this, skip to 2. Select the C++ components you require (I didn't know which I required, so I installed many of them). If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 → Modify → Individual Components and selected the required components. From other answers, important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features. Install/Modify these components for Visual Studio Build Tools 2017. This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools → Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools. Now enter python -m pip install --upgrade setuptools within this CMD window. Finally, in this same CMD window, pip install your Python library: pip install -U <library>.
如果Visual Studio不是你的东西，而你正在使用VS Code，那么这个链接将指导你通过安装程序让c++在你的Windows上运行。
您只需要完成先决条件部分。 https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites
这与其他答案相似，但这个链接可能比这里的一些回答更陈旧。
PS:别忘了运行pip install——upgrade setuptools
