Aborted
- 排查错误
这里有解决方案
http://rohitchauhanit.blogspot.com/2017/12/solution-of-fatal-python-error-pycurl.html
翻译过来如下：
[root@hadoop3 home]# cd /usr/lib64/
#从其他yum使用正常的机器搞一个过来
[root@hadoop3 lib64]# cp /root/libcurl.so.4.3.0 .
[root@hadoop3 lib64]# rm libcurl.so.4
[root@hadoop3 lib64]# ln -s libcurl.so.4.3.0 libcurl.so.4
[root@hadoop3 lib64]# rm libcurl.so
[root@hadoop3 lib64]# ln -s libcurl.so.4.3.0 libcurl.so
[root@hadoop3 lib64]# yum clean all
[root@hadoop3 lib64]# yum

总结：libcurl 依赖版本过低导致的（看样子），我的方法是从其他yum使用正常的机器上搞一个过来替换一下
