无法在 Windows virtualenv 上安装 pycrypto

Question

我正试图在我的Windows机器上安装pycrypto。我已经安装了mingw，distutils正在使用它。这里的错误是我得到的：

编辑：我发现了这个，但我不确定如何修复pip安装。http://ac-archive.sourceforge.net/largefile/largefiles_win32.print.html

Answer 1

我在windows中构建Fabric时遇到了同样的问题。原因是在构建pycrypto时mingw32的gcc配置。在configure中，gcc的设置-std被设置为c99。但是，当-std为c99时，定义了__STRECT_ANSI_，并跳过"sys/types.h"中的typedef_off_t off_t和_off64_t off64_t。我通过在mingw32中修改sys/types.h成功地构建了pycrypto，但这很残酷。

1. 创建一个虚拟（我通常把我所有的都放在桌面上）

2. 下载pycrypto的二进制文件（与您安装的python版本和架构匹配-目前不支持python3）-http://www.voidspace.org.uk/python/modules.shtml

3. 导航到您创建的virtualenv文件夹中的easy_install可执行文件（位于Libsite-packages下），并运行pycrypto安装：easy_install C:pathtothedownloadpycrypto-2.6.win-amd64-py2.7.exe
