Question

运行 fabric 时出现以下错误

(ENV)[root@server-124 ENV]# fab

AttributeError: 'module' object has no attribute 'HAVE_DECL_MPZ_POWM_SEC'

我提到了其他一些帖子，上面写着“所以你正在使用较新版本的 PyCrypto 和较旧版本的 _fastmath。”所以我也安装了gmp-devel

我正在使用 virtualenv , Centos 6, Python 2.6

请帮忙。

这为我解决了问题:

pip install PyCrypto==2.3

我没有卸载 python-crypto 因为我需要的其他包依赖于它。我刚刚运行了上面的 pip 命令，一切正常:)
