macOS High Sierraにしたらgitがエラーしたので解決してみた

【スポンサーリンク】

ラップトップを操作する手

macを「macOS High Sierra」にアプデしたら、gitがエラーを吐くようになってしまった……

今回発生した「git: error: unable to find utility "git", not a developer tool or in PATH」の解決方法を書いていきます。

解決方法

解決方法を端的に言うと

XCodeが古かったので入れ直して、ライセンスに同意!

というのが解決方法でした。

なんかめっちゃ出た……

なんだかここが大事そう。

sh: line 1:  3179 Abort trap: 6           /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -sdk macosx -find git 2> /dev/null
git: error: unable to find utility "git", not a developer tool or in PATH

ということでググってみた。

XCodeが原因?

参考になりそうなページを見つけました。

Fenrirの別のものに対しての解説だけど、詰まるところ「パス通ってないエラー」の模様。

blog.fenrir-inc.com

というかよくよく見ると、XCodeが原因のよう……なので確認してみると……

XCodeが古いせいで、High Sierraでは未対応のバージョンとなってしまっていたみたいです。

Yosemite(だったと思う)から、一気にアップデートした弊害でしょうか(笑)

XCodeの再インストール

XCodeが対応外のバージョンだったようなので、XCodeをアンインストール→インストール。

XCodeのインストール結構時間かかる……

30分以上かかったか……?(他のことしてたから詳しくはわからない)

改めてgitコマンドを実行

これでターミナルを開いて、改めてgitコマンドを叩いてみた

するとこのような表示に変わった!

Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.

「sudo xcodebuild -license」を叩けと言っているようです。

とりあえず叩く。

y-no-MacBook-Air:~ y$ git

要するに「Enter key押してね」と……

ヘルプ表示が出た!コレはイケてるぞ!

というわけで、SourceTreeでPullしてみると……

できたー!!!

あとがき

WindowsでもOSバージョンによって、動かなくなる……なんてことがありますが……

まさかそういうものだとは思いませんでした(笑)

macはずっと持っているだけで、実mac歴は短いので盲点でしたね(アプデも怠っていたし)。

Windowsと違って、macは普通のアプリをアップデートするかのように、OSアップデートが無料で入ったりするので、この辺の感覚が薄れていました。

ともあれ、困ったらエラーを読む、ググるくらいはしよう!と、怠惰なぼくは改めて思うのでした。
