【问题描述】：
我们最近开发了一个使用 RSA 的 API，主要问题是在控制台中它可以正常工作，但是一旦进入应用程序的“venv”，它就会显示不同的错误。

ImportError: No module named 'SocketServer'
M2Crypto 库已安装在 ubuntu 和 pip 中。
使用 RSA 的代码是：
def sella_xml(cfdi, numero_certificado, archivo_cer, archivo_pem):
keys = RSA.load_key(archivo_pem)
cert_file = open(archivo_cer, 'r')
cert = base64.b64encode(cert_file.read())
xdoc = ET.fromstring(cfdi)
xsl_root = ET.parse('cadenaoriginal_3_3.xslt')
xsl = ET.XSLT(xsl_root)
cadena_original = xsl(xdoc)
digest = hashlib.new('sha256', str(cadena_original)).digest()
sello = base64.b64encode(keys.sign(digest, "sha256"))
comp = xdoc.get('Comprobante')
xdoc.attrib['Sello'] = sello
xdoc.attrib['Certificado'] = cert
return ET.tostring(xdoc)
运行环境命令：
/root/merci_api/venv/bin/gunicorn --workers 3 -b localhost:5000 main:app
有什么建议吗？
我做错了什么？
【问题讨论】：
-
您能否从您的 virtualenv
python --version粘贴以下命令的输出 - 我认为它的 python 3.5 可以在堆栈跟踪中看到。python -c 'import six; print(six.__version__)'python -c 'import six.moves; print(dir(six.moves))' -
嗨@Varad，输出是：Python 2.7.12 和 1.10.0
-
这里有一些不正确的地方。查看您的堆栈跟踪，虚拟环境说的是 3.5，而您说的是 2.7
File "/root/merci_api/venv/lib/python3.5/site-packages/M2Crypto-0.25.1-py3.5-linux-x86_64.egg/M2Crypto/SSL/SSLServer.py", line 12, in <module> from SocketServer import BaseServer, ForkingMixIn, TCPServer, ThreadingMixIn。 -
实际上 venv 在 Python 3 上运行
-
解决了！似乎 M2Crypto 与 Python 3.5 不兼容我在我的 venv 上使用 Python 3.5 我将其更改为 2.7 并将 M2Crypto 的新版本升级为 0.26，该版本修复了 Linux 上的 SSLv2 ISSUE！
