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． 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．

$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．

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． [amazonjs asin=“B00HWLJI3U” locale=“JP” title=“実践Vim 思考のスピードで編集しよう！ (アスキー書籍)”]
