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。

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:

对于Python 3.7.4，以下一组命令可以工作: 在执行这些命令之前，您需要确认Visual Studio中已经安装了Desktop with c++ and Python。
cd "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build"
vcvarsall.bat x86_amd64
cd \
set CL=-FI"%VCINSTALLDIR%\tools\msvc\14.16.27023\include\stdint.h"
pip install pycrypto
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 Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient.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
看看这个包是否有一个正式的分叉，包括必要的二进制轮。
我需要包python-Levenshtein，有这个错误，并找到包python-Levenshtein-wheels。
使用Visual c++ 2015 Build Tools的链接。这将安装Visual c++ 14.0而不安装Visual Studio。
只要去https://www.lfd.uci.edu/~gohlke/pythonlibs/找到适合你的包(whl文件)。下载它。在cmd中进入下载文件夹，或者在文件夹的地址栏上输入'cmd'。执行如下命令:
pip install mysqlclient-1.4.6-cp38-cp38-win32.whl
(请正确输入文件名。我只是举了一个例子)。无需安装6GB大小的build toll cpp，您的问题将得到解决。
