Python的devel的蔭安裝錯誤

Question

安裝蟒-devel的的失敗，並附加消息

配置如下： - CentOS的7.2 - Python 2.7版安裝

1. 我重新運行與蔭負荷在輸出中建議使用，並且失敗時使用同樣的消
2. yum info python ==>已安裝的軟件包python 2.7.5 34.el7
3. yum info python-devel ==>未安裝。可用2.7.5 48.el7
4. yum deplist python-devel ==>依賴於python2.7.5-48.el7
5. 試圖安裝Python2.7.5-48.el7 wih「yum update python」，它失敗與python-devel install相同的錯誤信息。

Answer 1

刪除軟件包python-argparse和redhat-upgrade-tool。

然後做了一個yum安裝python-devel，這次它成功了。我認爲在較早的python 2.6上，這兩個軟件包有很大的依賴關係。

Answer 2

從百勝文檔，這裏的處理您的每5個錯誤的最安全的方式：

首先刪除重複項，並運行此之後仍不能解決任何錯誤：

package-cleanup --cleandupes 

如果上面帶有丟失的包清理錯誤，然後首先運行：

yum install yum-utils 

然後與處理其它4個錯誤：

yum reinstall grep-* 

其中grep- *是如在錯誤信息示出的包名稱。我在上面的命令中用*縮寫了其餘的grep版本名稱。

重複上面的命令爲其他3個被指示爲缺失的包。如果百勝命令爲您提供了錯誤，那麼嘗試一下本作只是一個包：

rpm -ivh --force grep-* 

然後終於從原始的錯誤消息重新運行百勝命令。

在您要清理剩餘的混亂，運行此命令的任何一點：

yum clean all 
package-cleanup --problems 

並遵循的方向。如需進一步參考，請查閱

man yum.conf 

Answer 3

問題是您在CentOS 7上，但安裝了CentOS 6軟件包。

• 蟒蛇-argparse-1.2.1-2.1.el6.noarch
• 紅帽升級工具-1：0.7.22-3.el6.centos.noarch

獲取列表所有已安裝的el6軟件包（rpm -qa | grep el6）並刪除它們或將它們更新到它們的el7等價物。你應該能夠刪除argparse，因爲它在2.7標準庫中。
