なんか気持ち悪いので update しまくった
こんなコマンドで一括で upgrade 可能だが依存関係やコンパイルなどで四苦八苦しながら upgrade するはめに
pip2 list -o | tail -n +3 | awk '{print $1}' | xargs pip2 install --upgrade
3時間くらい試行錯誤しながら update を終えると
Oh...... yum が動かない・・・・・・
# yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (none/other)
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Nov 16 2020, 22:23:17)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
復旧してみる
pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (none/other)
と言われているので、 pycurl の upgrade がまずかったのであろう
とりあえず pycurl を再インストール
参考:yumコマンドを実行するとpycurlでエラーになる
pip2 uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
pip2 install pycurl
Collecting pycurl
Using cached pycurl-7.43.0.5.tar.gz (216 kB)
Using legacy 'setup.py install' for pycurl, since package 'wheel' is not installed.
Installing collected packages: pycurl
Running setup.py install for pycurl ... done
Successfully installed pycurl-7.43.0.5
さてどうかな？
yum update

If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
Oh..... もっと複雑になった・・・・・・
pycurl のバージョンを指定して再インストールなど何度か色々と試したがさっぱり刃が立たず
pip2 を再インストール
まずは pip2 のモジュールを削除
python -m pip uninstall pip
続いてパッケージの削除とインストール
rpm -ev python2-pip-8.1.2-14.el7
rpm -ivh python2-pip-8.1.2-14.el7.noarch.rpm
さぁどうだ？

yum-langpacks のパッケージインストール
しばらく進めていくと
ERROR: Could not find a version that satisfies the requirement yum-langpacks==0.4.2 (from versions: none)
ERROR: No matching distribution found for yum-langpacks==0.4.2
と言われるので、これは真面目に入れておこう
No matching distribution found for yum-langpacks==0.4.2
と言っているので pip でのインストールではなくパッケージなのだろうと推測
CentOS のパッケージリストを探すとパッケージが存在するのでダウンロードしてインストール
