suse 11 pip pip3使用过程中遇到的各种问题
在安装完成python3.6后，使用pip3安装某些插件，报如下错误
linux-9qk9:~ # pip3 install ipython pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting ipython Could not fetch URL https://pypi.python.org/simple/ipython/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping Could not find a version that satisfies the requirement ipython (from versions: ) No matching distribution found for ipython
我们进入Python3,结果查看到没有安装ssl,由于我们使用的是suse11系统，不想centos有Yum源可以使用命令yum install openssl-devel -y 进行ssl-devel安装，那怎么办呢，baidu了一下需要安装libopenssl，我们就把原来安装的Python3删除重新安装下

linux-9qk9:~ # rm -rf /usr/local/python3 //删除原来安装的python3
安装libopenssl-devel, 这个有点类似centos里面的openssl-devel包，注意版本

Summary : Secure Sockets and Transport Layer Security
Description :
The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, full-featured, and open source toolkit implementing
the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS
v1) protocols with full-strength cryptography. The project is managed
by a worldwide community of volunteers that use the Internet to
communicate, plan, and develop the OpenSSL toolkit and its related
documentation.
Derivation and License
OpenSSL is based on the excellent SSLeay library developed by Eric A.
Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an
Apache-style license, which basically means that you are free to get it
and to use it for commercial and noncommercial purposes.
Please read the file /usr/share/doc/packages/openssl/README-FIPS.txt
for information on FIPS-140-2 compliant mode of operation of the
openssl shared libraries.

ps,如果安装了libopenssl-devel还是不行的话，我们就要去找一台已经import ssl不报错的机器比如下面那台机器，
将_ssl.cpython-36m-x86_64-linux-gnu.so复制到/usr/local/python3/lib/python3.6/lib-dynload目录下面就可以了
inspect01:/usr/local/python3/lib/python3.6/lib-dynload # ls *ssl*

安装好以后我们在用Pip3测试下能否安装软件，可以看到这个报错像是网络不通的样子

那我们来ping 一下baidu看看能不能ping通，我们看到是可以ping通的,
linux-9qk9:/tmp/software_download # ping www.baidu.com PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data. 64 bytes from 61.135.169.121: icmp_seq=1 ttl=50 time=25.0 ms 64 bytes from 61.135.169.121: icmp_seq=2 ttl=50 time=27.5 ms ^C --- www.a.shifen.com ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1001ms rtt min/avg/max/mdev = 25.073/26.292/27.511/1.219 ms linux-9qk9:/tmp/software_download #
那么这个是怎么一回事呢，网上搜索了很久有的说是要修改镜像源头,比如下面这个链接写的那样
https://www.cnblogs.com/biglittleant/p/6944180.html
我们按照他的方式改下看看
linux-9qk9:/tmp/software_download # mkdir ~/.pip
linux-9qk9:/tmp/software_download # vim ~/.pip/pip.conf [global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host = mirrors.aliyun.com
:wq!
重新测试下Pip3发现还是不行，

这下比较麻烦了，搜索了半天百度也没发现什么好的解决办法，网也通的，镜像也设置了，还能怎么搞呢，后来想来想去估计还是网络问题，我们先把他的国内镜像删除
linux-9qk9:/tmp/software_download # rm -rf ~/.pip
查看网络，我这里虚拟机用的是一个网卡，桥接模式

重新用pip3安装，发现报错不一样了，这是一个好现象，
