我正在使用Suse Linux Enterprise 11 SP4,并且尝试使用pip安装python软件包,但失败并出现以下错误:

Env:

$ 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:

我尝试过all this solutions,但是他们都没有从事SLES的工作。

有什么想法吗?

预先感谢

答案 0 :(得分:0)

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:

尝试使用包装轮进行安装

最后我明白了!

似乎默认情况下在SLES 11 SP4(libopenssl-devel)上默认安装的openssl库(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

技巧是像这样卸载 libopenssl-devel安装 libopenssl1-devel

重要提示:请注意,系统会要求您选择一个选项,请选择卸载libopenssl-devel-0.9.x-x.xxx.x.x.x

$ 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

现在可以使用以下命令重新编译/重新安装python env:

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

最后确认您的OpenSSL版本是新版本,然后继续使用pip安装软件包:

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

$ pip install sendgrid
