macOS High Sierraにしたらvimが使えなくなった件

どうもしののめ(@Shinogasa)です.

先日macOS High Sierraにアップデートした際にvimが使えなくなってしまいました．

$ vim
dyld: Library not loaded: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/libruby.2.0.0.dylib
  Referenced from: /usr/local/bin/vim
  Reason: image not found
Abort trap: 6

こりゃいかんと思い色々調べてたところ下記ブログに解決策が．

ありがとうございます．
コマンド実行．

$ brew upgrade vim

Error: GitHub
The GitHub credentials in the macOS keychain may be invalid.
Clear them with:
  printf "protocol=https\nhost=github.com\n" | git credential-osxkeychain erase
Or create a personal access token:
  https://github.com/settings/tokens/new?scopes=gist,public_repo&description=Homebrew
and then set the token as: export HOMEBREW_GITHUB_API_TOKEN="your_new_token"

なにやらGitHubのキーチェーンがおかしいっぽい？
とりあえずエラーでググったら下記ページがヒット．

Updating credentials from the OSX Keychain - User Documentation

説明通り
Space+Ctrlで「Keychain Access.app」を検索
↓
github.comを検索

したらキーチェンがヒットしない．
別のエラーでググったら下記記事がヒット．

qiita.com

git configしてやればエエのじゃな．

$ git config --global credential.helper osxkeychain
$

何も出ない．とりあえずもう一度upgrade．

今度はPython.hが無いとな？ pyenvで変えてるからかしら？

$ pyenv global system

systemのpythonに変更．
もう1度upgradeしてみたけどダメ．
今度は下記のstack overflowの回答を実行．

ja.stackoverflow.com

$brew install python
Error: python 2.7.11 is already installed
To upgrade to 2.7.14, run `brew upgrade python`

そりゃpython入ってるもんな，と思ったらバージョン上げれるよって．
上げてみましょう．

$ brew upgrade python

無事アップグレード出来たっぽい．
もう1度vimアップグレードじゃ．

無事アップグレードされましたねー．
vimコマンドでしっかり起動するようになりました．

High Sierraにアップデートしたらその他いろいろアップグレードする必要があるんですね．
