python(twisted) 在 MAC 中安装 openssl 时出错？

Question

我已经在 MAC(V 10.11.3) 中安装了 Openssl

# brew upgrade
#brew install openssl
Warning: openssl 1.0.2l is already installed

我也运行了以下命令；

easy_install PyOpenSSL

easy_install PyCrypto

所有这些命令安装都没有问题。

并尝试将 openssl 与 brew 链接

#brew link openssl

得到

Warning: Refusing to link: openssl

    Linking keg-only openssl means you may end up linking against the insecure,
    deprecated system OpenSSL while using the headers from Homebrew's openssl.
    Instead, pass the full include/library paths to your compiler e.g.:
      -I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib

但如果我尝试;

 brew link /usr/local/opt/openssl/bin --force (or, **lib**, **include** folders)

所有地点都一样

Error: No available formula with the name "/usr/local/opt/openssl/bin"

现在当我在 python 命令提示符下尝试时；

>>> from twisted.internet import reactor, endpoints

我收到以下错误

AttributeError: 'module' object has no attribute 'OP_NO_TLSv1_1'

我该如何解决这个问题？

编辑

如果我尝试

>>> import OpenSSL

没有打印

但如果我尝试

>>> import twisted.internet.ssl

我遇到了上述问题。

我安装了以下扭曲版本；

>>> import twisted
>>> twisted.__version__
'17.9.0rc1'
>>> 

Answer 1

我通过安装最新版本的 twisted

解决了这个问题

#sudo pip install twisted==13.1.0
