在qPython中安装Win7

Question

作为一个使用Python和KDB+/Q的新手，我尝试安装qPython包(Python用于KDB+，不要被误认为是QPython)。

1. 我从https://github.com/exxeleron/qPython/releases/tag/qPython-1.0-RC1下载并解压缩了源代码
2. 在Win cmd中，我运行了python setup.py install (从上面步骤1给出的路径)
3. 收到以下带有错误的日志。

它到底说了什么，我该怎么做？

Answer 1

看来这就是罪魁祸首：

g:/r/rtools/gcc-4.6.3/bin/../lib/gcc/i686-w64-mingw32/4.6.3/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lpython27

是的，我想说的是，您需要安装python27才能获得链接到的python27库。

Answer 2

I已经在windows vista上安装了qpython，如下所示：

从：https://github.com/exxeleron/qPython/archive/qPython-1.0-RC2.zip下载了zip文件

在命令提示符中解压缩并执行以下操作：

python -m pip install -r requirements.txt

在这个阶段，它给出了错误" error : Microsoft Visual C++ 9.0是必需的(无法找到vcvarsall.bat)。

所以，下载所需的文件http://aka.ms/vcpython27并安装它。

再次执行: python安装-m -r requirements.txt

它花费了大约30分钟，并安装了qpython所需的所有模块。

试图通过以下方式安装qpython：

python setup.py install

得到错误：“错误:找不到vcvarsall.bat”。

已安装Visual 2010速递：http://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express

又花了30分钟安装。

创建了名为“VS90COMNTOOLS”和值“C：\Program\MicrosoftVisualStudio10.0\Common7\Tools\‘的新系统环境变量

最后，通过运行命令(在一个新的dos窗口中)成功安装了qpython：

python setup.py install
