您好，我在构建python映像时遇到问题

错误说

但当提升pip时，同样的错误也会出现

错误：由于环境原因无法安装程序包错误：HTTPSConnectionPool（host='files.pythonhosted.org'，port=443）：url超过了最大重试次数：/packages/ac/cf/0cc542fc93de2f3b9b53cb979c7d118cffb93204afb46299a9f858e113f/pip-21.1-py3-none-any.whl（由SSLError引起）（sslcertverificationoner（1），[SSL:CERTIFICATE\u VERIFY\u失败]证书验证失败：无法获取本地颁发者证书（_ssl.c:1123'））

我试过了， 在我的docker文件中运行pip install--trusted host=pypi.python.org--trusted host=pypi.org--trusted host=files.pythonhosted.org-r requirements.txt，但这对我没有帮助

我尝试过，卸载所有python解释器并重新安装，但结果相同

我们没有使用代理服务器，我可以正常ping files.pythonhosted.org

希望有人能在这方面帮助我。谢谢。

验证证书是否到位

~ $ python3.7 -c "import ssl; print(ssl.get_default_verify_paths())"
DefaultVerifyPaths(
cafile='/etc/pki/tls/cert.pem', 
capath='/etc/pki/tls/certs', 
openssl_cafile_env='SSL_CERT_FILE', 
openssl_cafile='/etc/pki/tls/cert.pem', 
openssl_capath_env='SSL_CERT_DIR', 
openssl_capath='/etc/pki/tls/certs')

大家好，Sandeep Kumar Chenna，这里是结果。默认验证路径（cafile=None，capath=None，openssl\u cafile\u env='SSL\u CERT\u FILE'，openssl\u cafile='C:\\Program Files\\Common Files\\SSL/CERT.pem'，openssl\u capath\u env='SSL\u CERT\u DIR'，openssl\u capath='C:\\Program Files\\Common Files\\SSL/certs'）请查看以下帖子：和。
