对于初学
Linux
的人来说，太多的
Linux
内核版本会让人不知所措，并且刚开始需要我们
下载
各种编译器、软件包去调试我们的环境。这个
时
候肯定就需要我们
使用
到安装
下载
的工具。所以这里就来一起学习
Linux
中
yum
、wget、apt-get的用法和区别吧。
一、常见
Linux
发行版本
最近在工作中发现一个问题，
yum
无法
使用
，
报错
如下：
/usr/lib64/
py
thon2.7/site-packages/
py
curl
.so: undefined symbol: CRYPTO_num_locks
ldd /usr/lib64/
py
thon2.7/site-packages/
py
curl
.so 查看一下动态库连接
注意：lib
curl
的位置
查看一下lib
curl
是否有什么异常的配置
ldconfig -v | grep lib
curl
发现两个lib
curl
检查ld.so.conf的配置
对比正常的测试机
根据前面的ldd来看，去掉local lib

在执行
yum
命令
时
，出现如下错误：
py
curl
: lib
curl
link-time version is older than compile-time version
错误的原因就是
py
curl
的版本太旧了，解决方案就是重装下
py
curl
。
重装命令较为简单，先卸载（最好执行两次）
pip uninstall
py
curl
pip install
py
curl
...
cargo build
