python pip 包安装失败， 'fixing' : "unable to find vcvarsall.bat" 后出现 dllwrap 错误

Question

我在文件中找不到这个。 mingw/msys有什么不对的地方吗？[我需要修复 vcvarsall.bat，这样我才能安装其他包。]

使用 pip.exe 安装 python 包 'twisted' 失败。

我安装了 python2.6 和 mingw/msys。%PATH% 包括 C:\MinGW\ 和 C:\MinGW\mingw32\bin

首先:pip.exe install twisted 失败，提示 error: Unable to find vcvarsall.bat我创建文件 G:\Programs (x86)\Python 2.6\Lib\distutils\distutils.cfg，其中包含:

[build]
compiler=mingw32

现在我得到的错误是:

Answer 1

这可能是 Python 的一个错误。参见 http://bugs.python.org/issue2698

与此同时，您可以安装 ActivePython和 install Twisted通过 PyPM(不需要编译器)。

或者，您可以使用 the official binary ...尽管我推荐上述解决方案，因为您将来可以轻松“升级”到更新版本的 Twisted。
