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_CHECKAttributeError: 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pipsudo apt-get remove python3-pip# 下载pipwget 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-22.2.2python3 setup.py install# 查询版本root@ubuntu:/home/ubuntu/# pip3 --versionpip 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
