Question

我试图在Windows 7 python3.5和RHEL6.x python3.3中安装 ctypes 模块但是不接受错误..

  File "C:\Users\sawad\Downloads\ctypes-1.0.2\setup.py", line 24
    raise Exception, "ctypes %s requires Python 2.3 or better" % __version__
                   ^
SyntaxError: invalid syntax

当我使用python版本2.6.6时，它会给出错误..

running install
running build
running build_py
running build_ext
building '_ctypes' extension

...省略

source/_ctypes.c:4392: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘Pointer_Type’

source/_ctypes.c:4632: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘init_ctypes’
error: command 'gcc' failed with exit status 1

我经常下载.tar.gz包，然后使用“python3 setup.py install”安装它，因为我的服务器没有直接的Internet访问权限。那怎么能起作用呢？

您根本不需要安装ctypes ;它是Python标准库的一部分，从Python 2.5开始。请参阅module documentation。

ctypes 1.0.2是古老的，不要使用它。它是为Python 2.3和2.4编写的，从未调整为在Python 3上运行，这就是为什么你会得到语法错误。您在Python 2中遇到了错误，因为您缺少Python开发标头（由python-devel RPM提供）。

在Windows 7 / RHEL 6.x python3.x中安装ctypes
