调用importsetuptools将对补丁distutils进行模仿，以强制与Visual Studio兼容。手动调用vcvars32.bat将设置虚拟环境并防止编译器抛出其他常见错误。对于VS 2017，文件位于

“C:\Program Files（x86）\Microsoft VisualStudio\2017\社区\VC\Auxiliary\Build\vcvars32.bat“

以下是我用来将.pyx文件快速编译为.pyd的安装脚本：（注意：它使用第三方模块发送2个

看起来它正在寻找VC编译器，所以您可以尝试使用-c mingw32提及编译器类型，因为您有msys

python setup.py install -c mingw32

发生什么事？Python模块可以部分用C或C++编写（通常是为了速度）。如果您尝试用Pip（或setup.py）安装这样的包，它必须从源代码编译C/C++。开箱即用，Pip会厚颜无耻地假设您安装了Microsoft Visual C++编译器。如果您没有它，您将看到这条神秘的错误消息“错误：无法找到vcvarsall.bat”。

规定的解决方案是安装C/C++编译器，或者Microsoft Visual C++，或者MinGW（一个开源项目）。然而，安装和配置两者都非常困难。（编辑2014：微软发布了一个专门针对Python 2.7的C++编译器）

最简单的解决方案是为流行的Python包使用Christoph Gohlke的Windows安装程序（.msi）。他为Python2.x和3.x、32位和64位构建安装程序。您可以从http://www.lfd.uci.edu/~gohlke/pythonlibs/

如果你也认为“错误：找不到vcvarsall.bat”是一条荒谬而晦涩且毫无帮助的消息，那么请在http://bugs.python.org/issue2943将其替换为更有用、更友好的信息。

相比之下，Ruby附带了一个包管理器Gem，并提供了一个准官方的C/C++编译器DevKit。如果您尝试安装不带软件包的软件包，您会看到以下有用的友好信息：

请更新PATH以包含构建工具或从下载DevKithttp://rubyinstaller.org/downloads并遵循以下说明http://github.com/oneclick/rubyinstaller/wiki/Development-Kit

我找到了解决方案。我也遇到了同样的问题和错误，安装“amara”。我安装了mingw32，但需要配置distutils。

我已经安装了Python 2.6。我将mingw32安装到C:\programs\mingw\将mingw32的bin目录添加到环境变量：append c:\programs\MinGW\bin；到PATH将位于C:\Python26\Lib\distutils\distutils.cfg的distutils.cfg文件编辑为：[生成]编译器=mingw32现在运行easy_install.exe amara。

确保通过打开新的cmd.exe来设置环境。

使用此链接下载并安装Visual C++2015生成工具。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安装，您将不会再次出现错误。

我已经在以下平台和版本上测试了它：

Python 3.6 on Windows 7 64-bit
Python 3.7 on Windows Server 2016 (64-bit system)
Python 3.8 on Windows 10 64-bit

我没有看到任何使用vswhere的答案，我认为这是自Visual Studio 15.2以来正确的方法。

下面是我运行vsvars64.bat的方法（我想这与vsvarsall类似）

def init_vsvars():
    cprint("")
    cprint_header("Initializing vs vars")
    vswhere_path = r"%ProgramFiles(x86)%/Microsoft Visual Studio/Installer/vswhere.exe"
    vswhere_path = path.expandvars(vswhere_path)
    if not path.exists(vswhere_path):
        raise EnvironmentError("vswhere.exe not found at: %s", vswhere_path)

    vs_path = common.run_process(".", vswhere_path,
                                 ["-latest", "-property", "installationPath"])
    vs_path = vs_path.rstrip()

    vsvars_path = os.path.join(vs_path, "VC/Auxiliary/Build/vcvars64.bat")
    # common.run_process(".", vsvars_path, [])
    os.system('"%s"' % vsvars_path)

run_process做了很多事情，但基本上归结为：

    output = ""
    process = subprocess.Popen(
        commandline,
        stdout=subprocess.PIPE,
        stderr=subprocess.STDOUT,
        universal_newlines=True)
    for stdout_line in iter(process.stdout.readline, ""):
        cprint(stdout_line)
        output += stdout_line
    process.stdout.close()

    return_code = process.wait()
    return output
