python pip包安装失败，dllwrap error after'fixing'：“找不到vcvarsall.bat”

Question

我在档案里找不到这个。mingw/msys有什么不对的地方吗？ [我需要修复vcvarsall.bat，以便安装其他软件包。]

无法使用pip.exe安装python包“twisted”。

我已经安装了python2.6和mingw/msys。 %路径%包括C:\MinGW\和C:\MinGW\mingw32\bin

首先：pip.exe install twisted通过说error: Unable to find vcvarsall.bat失败 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：

问题：为什么dllwrap会在pip中给出这个错误？

_foo.exp: file not recognized: File format not recognized

简而言之：检查你的路径。MinGW\bin需要在它的开始附近。

长话短说：有一段时间我在利用一个工作。我从pip.log中获取dllwrap命令并直接执行它。它构建了.pyd并使pip安装能够完成任务。

我将--verbose标志传递到这两种调用dllwrap的不同方法中。在皮普的领导下，这件事已经完成了。

dlltool: Opened temporary file: dumlc.s
dlltool: run: as   -o _bcrypt.exp dumlc.s
dlltool: Generated exports file

从命令行调用dllwrap得到了这个结果。

C:\MinGW\bin\dlltool: Opened temporary file: demmc.s
C:\MinGW\bin\dlltool: run: C:\MinGW\bin\as   -o _bcrypt.exp demmc.s
C:\MinGW\bin\dlltool: Generated exports file

我的计算机运行的是64位的Windows7，但使用的是32位的Python2.7。它是新的，但似乎已经预装了AMD应用程序SDK。它有一个默认为64位输出的as.exe。

我的修复方法是编辑路径，使C:\ MinGW\bin领先于C:\程序文件（x86）\ AMD APP\bin\x86\u 64

这个问题可以在Python代码中得到更可靠的解决，尽管我还没有确定在virtualenv、pip或distutils中应该做什么。

使用MinGW构建扩展还需要另外两件事，我将在这里简单地重复一下。

配置distutils以使用MinGW编译器

这可以在各种文件或命令行开关中完成。我在主目录中选择了一个文件。

$ cat ~/pydistutils.cfg
[build]
compiler = mingw32

消除-mno cygwin开关的补丁程序

作为管理员编辑Lib/distutils/cygwinccompiler.py。删除四个-mno cygwin选项。

s/ -mno-cygwin//

-mno cygwin在gcc中已被弃用一段时间，现在是一个错误。

Answer 2

这可能是Python的一个bug。见http://bugs.python.org/issue2698

同时，您可以通过PyPM安装ActivePython和install Twisted（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，因为您可以在将来轻松地“升级”到Twisted的新版本。

Answer 3

在Windows上，我安装了Visual Studio 2008（vcsetup.exe）来解决此问题。

如果使用Python 3.3，则可以使用Visual Studio 2010
