我在 Suse Linux Enterprise 11 SP4 上，我正在尝试使用 pip 安装 python 包，但它失败并出现以下错误：

环境：

$ python --version
Python 3.6.6

$ pip --version
pip 10.0.1 from /home/<<user>>/.pyenv/versions/3.6.6/lib/python3.6/site-packages/pip (python 3.6)

命令：

$ pip install sendgrid

错误：

我已经尝试了所有这些解决方案，但它们都没有在 SLES 上工作。

有任何想法吗？

您可以通过将 pypi.org 和 files.pythonhosted.org 设置为受信任的主机来忽略 SSL 错误。

pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

或者：

尝试使用包的轮子安装

最后我让它工作！

似乎 SLES 11 SP4 () 上默认安装的 openssl 库libopenssl-devel确实已经过时了 ( OpenSSL 0.9.8)

要验证这一点，您可以运行：

$ python -c "import ssl; print(ssl.OPENSSL_VERSION)"
OpenSSL 0.9.8j-fips 07 Jan 2009

诀窍是像这样卸载 libopenssl-devel和安装 libopenssl1-devel：

重要提示：请注意，您将被要求选择一个选项，请选择卸载 libopenssl-devel-0.9.xx.xxx.xxx

$ sudo zypper install libopenssl1-devel

 Solution 1: deinstallation of libopenssl-devel-0.9.8j-0.106.9.1.x86_64
 Solution 2: do not install libopenssl1-devel-1.0.1g-0.58.9.1.x86_64

Removing libopenssl-devel-0.9.8j-0.106.9.1 [done]
Installing: libopenssl1-devel-1.0.1g-0.58.9.1 [done]

现在继续重新编译/重新安装您的python env：

$ CFLAGS=-I/usr/include/openssl1 LDFLAGS=-L/usr/lib64 pyenv install 3.6.6

最后验证您的OpenSSL版本是新版本并继续安装您的软件包pip：

$ python -c "import ssl; print(ssl.OPENSSL_VERSION)"
OpenSSL 1.0.1g 7 Apr 2014

$ pip install sendgrid

希望对你有帮助！
