按照官网上的说明安装并运行Pyzip 时遇到如下的错误

【code】

首先我们找到"D:\sdk\zwave\zip\pyzip\dtls\openssl.py"这个文件的line 79，看看code是什么原因引起的

#
# Library loading
#
if sys.platform.startswith('win'):
    #dll_path = path.abspath(path.dirname(__file__))
    if (platform.architecture()[0] == "64bit"):
         dll_path = "C:\OpenSSL-Win64"
    else:
         dll_path = "C:\OpenSSL-Win32"
    debug_cryptodll_path = path.join(dll_path, "cygcrypto-1.0.0.dll")
    debug_ssldll_path = path.join(dll_path, "cygssl-1.0.0.dll")
    release_cryptodll_path = path.join(dll_path, "libeay32.dll")
    release_ssldll_path = path.join(dll_path, "ssleay32.dll")
    if path.exists(path.join(dll_path, "use_debug_openssl")) and \
      path.exists(debug_cryptodll_path) and \
      path.exists(debug_ssldll_path):
        libcrypto = CDLL(debug_cryptodll_path)
        libssl = CDLL(debug_ssldll_path)
    else:
        # If these don't exist, then let the exception propagate
        libcrypto = CDLL(release_cryptodll_path)
        libssl = CDLL(release_ssldll_path)
elif sys.platform.startswith('darwin'):
    libcrypto = CDLL("/opt/local/lib/libcrypto.1.0.0.dylib")
    libssl = CDLL("/opt/local/lib/libssl.1.0.0.dylib")
else:
    libcrypto = CDLL("libcrypto.so.1.0.0")
    libssl = CDLL("libssl.so.1.0.0")

那么就是在"C:\OpenSSL-Win64"这个文件夹找不到libeay32.dll和ssleay32.dll这两个动态库；

而 install DTLS

python setup.py install 

时，它安装的目录可能是C:\Python27\Lib\site-packages\dtls； 并不存在"C:\OpenSSL-Win64"这个文件夹。

【解决】

根据上面的code，创建"C:\OpenSSL-Win64"这个文件夹，并找到libeay32.dll和ssleay32.dll，将它们拷贝过去。再运行就OK了
