python - 安装numpy - 系统找不到指定的文件(msvcr90.dll)

Question

过去几个小时我一直在尝试安装 numpy，但我最终放弃并寻求帮助。

首先，我尝试过:

我首先收到“无法找到 vcvarsall.bat”错误，因此我按照此问题 ( error: Unable to find vcvarsall.bat ) 的建议安装了 Microsoft Visual V++ 2008 Express。这绝对没有任何作用。

然后我尝试通过安装 mingw32 并使用以下命令创建 disutils.cfg 文件来完全使用不同的编译器:

[build]
compiler = mingw32

并将其放入Python27\Lib\distutils

这消除了“无法找到 vcvarsall.bat”错误，但现在我遇到了有关 msvcr90.dll 的新错误。

我不知道如何解决它，我很累，只想 numpy 哈哈。这是我运行 python setup.py install 时的完整输出:

您可以直接使用二进制可执行文件安装，而不是从源代码安装。为您提供 32 位 http://docs.scipy.org/doc/numpy/user/install.html#windows或者正如您在 http://www.lfd.uci.edu/~gohlke/pythonlibs/ 中指出的 64 位版本
