Error during the Java installation process: git installができないどころかbrew updateすらもできない

Last updated at Posted at 2016-03-02

夏にjavaの授業を取る予定なので先取りしようとクラスのHP参考にbrew install gitを動かそうとしするもこんなエラーを吐く。。

stackoverflowでざっとスキミングしながらback to backしても全く改善の余地なし。以下、直接的な問題の解決という点ではあまり参考にならなかったリンク：

*とは言えhomebrew周辺の構造理解に少しでも役に立ったということは言うまでもないので興味のある方は自分もエラーを吐いた気に鳴って読んでみると面白いかもしれない。

そこで包括的にググってみることに。なんでこれを最初にしなかったのか。。

すると最初のトップページで以下のようなリンクを発見:

homebrew not working on OSXに書いてあるとおりにやってみる:

First, open terminal and cd /usr/local/, and git status to see if Homebrew is clean.
if dirty, git reset --hard && git clean -df
then brew doctor, brew update

On branch master

no changes added to commit (use "git add" and/or "git commit -a")

これは汚いと考えてよろしいのでしょうか。。とりあえずgit reset --hard && git clean -dfを実行してみることに。

HEAD is now at ce8f101 Update minitest

と返ってきたのでbrew doctorとbrew updateをもう一度実行。まだ同じエラーを吐く。

warning: unable to unlink CONTRIBUTING.md: Permission denied
warning: unable to unlink SUPPORTERS.md: Permission denied
fatal: cannot create directory at '.github': Permission denied

どうやら/usr/local内の権限に問題があるのでは？と判断したので上記のリンク周辺を参考にsudo chown -R $(whoami):admin /usr/localを実行し、もう一度brew doctorとbrew updateをするも状況は変わらず。そこでpermissionを変更した後にgit reset --hard && git clean -dfをやったら何か変わるのでは？と考え試しに行ってみる。その後brew doctorとbrew updateを実行するとさっきとは少しだけ違うメッセージを受け取る:

いちいち報告している暇がなかったので警告をシカトしてもう一度brew update:

Already up-to-date.

この一言までたどり着くのに長かった。。念のためもう一度brew doctorを行い最後にもう一度brew install gitを実行。
