解决Python中的AttributeError: module ‘lib‘ has no attribute ‘X509_V_FLAG_CB_ISSUER_CHECK‘错误

问题描述

树莓派ubuntu系统下python3执行报错如下：


  File "/usr/share/python-wheels/urllib3-1.25.8-py2.py3-none-any.whl/urllib3/contrib/pyopenssl.py", line 46, in <module>
  File "/usr/lib/python3/dist-packages/OpenSSL/__init__.py", line 8, in <module>
    from OpenSSL import crypto, SSL
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1553, in <module>
    class X509StoreFlags(object):
  File "/usr/lib/python3/dist-packages/OpenSSL/crypto.py", line 1573, in X509StoreFlags
    CB_ISSUER_CHECK = _lib.X509_V_FLAG_CB_ISSUER_CHECK
AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK'

原因分析：

pyOpenSSL版本与python版本不匹配

解决方案：

重新安装pip和pyOpenSSL

# 卸载pip
sudo apt-get remove python3-pip
# 下载pip
wget https://files.pythonhosted.org/packages/4b/30/e15b806597e67057e07a5acdc135216ccbf76a5f1681a324533b61066b0b/pip-22.2.2.tar.gz
# 解压
tar xf pip-22.2.2.tar.gz
# 安装
cd pip-22.2.2
python3 setup.py install
# 查询版本
root@ubuntu:/home/ubuntu/# pip3 --version
pip 22.2.2 from /usr/local/lib/python3.8/dist-packages/pip-22.2.2-py3.8.egg/pip (python 3.8)

安装匹配的 pyOpenSSL

>root@ubuntu:/home/ubuntu/# pip3 install pyOpenSSL --upgrade
