我试图安装Python包dulwich:
pip install dulwich
但我得到一个神秘的错误信息:
error: Unable to find vcvarsall.bat
如果我尝试手动安装包,也会发生同样的情况:
> python setup.py install

error: Unable to find vcvarsall.bat
Virtualenv非常棒:它让我可以保留许多不同的Python安装,这样不同项目的依赖关系就不会全部集中在一起.
但是,如果我想在Windows上安装一个打包为.exe安装程序的软件包,我如何指导它安装到virtualenv？例如,我有pycuda-0.94rc.win32-py2.6.exe.当我运行它时,它会检查注册表,并且只找到一个要安装的Python26,这是我的virtualenv所基于的常见的.

我正在使用Vista,并使用Python 2.6.4.我正在使用一个使用Python脚本的软件,但碰到了这个消息:
cannot find vcvarsall.bat
所以,我安装了visual c ++ 2010.仍然找不到文件 - 但是,它就在那里.我的猜测(一个非常没有受过教育的人......)是路径错误的地方,因为我还有一个旧的视觉2008(非常空)文件夹.我不知道在哪里对新路径进行更改.我是否在注册表或脚本中更改了某些内容？或者别的地方？

我已经按照这些stackover流程问题中找到的解决方案.没有任何效果.

说明提供了两个选项.
选项1
如果你有pip(命令行假定它找到属于PyPy的pip,而不是CPython中的pip):
pip install git+https://bitbucket.org/pypy/numpy.git
这似乎是一个很好的选择,但我pip在目录结构中找不到我解压缩.
选项2
或者,直接的方式:
git clone https://bitbucket.org/pypy/numpy.git
cd numpy
pypy setup.py install
我没有登录gitWindows,但我也怀疑这个选项可能涉及从Windows编译源代码https://bitbucket.org/pypy/numpy.git,甚至可能无法(或需要大量黑客攻击).
编辑
通过安装PIP https://sites.google.com/site/pydatalog/python/pip-for-windows按照下面的答案,或在说明这个答案的问题,我如何在Windows上安装PIP？,失败了ConnectionError: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /packages/py2.py3/p/pip/pip-1.5.4-py2.py3-none-any.whl (Caused by <class 'httplib.BadStatusLine'>: '').例如,参见此错误报告.不过,我是能够通过微软的Visual Studio安装PIP PTVS通过右键单击在Solution Explorer中的Python环境PyPy 2.7,选择安装Python包.这无法安装numpy(另一个连接错误),但确实安装了pip.
现在我有了pip,我尝试使用命令行安装numpy pip install git+https://bitbucket.org/pypy/numpy.git.首先我需要安装git才能做到这一点......没问题.但随后它失败了以下
