centos7 安裝rpm包依賴問題
通常我們安裝rpm包時，先cd xx.rpm進入rpm包目錄
然後執行 rpm -ivh xx.rpm
如果沒問題那就安裝成功了，然而，事情通常都不如我們所願。
比如：執行命令安裝python3.5的時候：
rpm -ivh sclo-python35-python3-py-1.4.34-1.3.el7.noarch.rpm
會報出如下錯誤：
error: Failed dependencies:
rh-python35-python(abi) = 3.5 is needed by sclo-python35-python3-py-1.4.34-1.3.el7.noarch
rh-python35-python-setuptools is needed by sclo-python35-python3-py-1.4.34-1.3.el7.noarch
rh-python35-runtime is needed by sclo-python35-python3-py-1.4.34-1.3.el7.noarch
除此之外還有很多其他的包也會出現這個問題，那怎麼辦呢？
經過探索終於發現瞭解決問題的方法：採用yum的方式安裝，yum會自動解決rpm依賴問題
yum install -y sclo-python35-python3-py-1.4.34-1.3.el7.noarch.rpm
結果如下：
