[Vagrant] VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOTエラー対処法

2018年9月27日 @84kure

あるときから以下のエラーが出るようになる。これまではエラーなしでVMは起動できていたのだけどなんでだろ？Windows Updateの影響？

ネットで対処法を調べると、Hyper-Vを明示的に無効化すれば解決するらしい。

以下の手順でHyper-Vを無効化する。

1. OptionalFeatures.exeを実行してHyper-Vをアンチェックする。

2. 管理者権限でコマンドプロンプトを開いて以下を実行する。

> bcdedit /set hypervisorlaunchtype off

1	> bcdedit /set hypervisorlaunchtype off

[Vagrant] ホームディレクトリを変更する

2018年9月27日 @84kure

デフォルトは ~/.vagrant.d だけど、環境変数 VAGRANT_HOME を設定することで変更できる。

$ setx VAGRANT_HOME "D:\Users\84kure\.vagrant.d"
$ echo $VAGRANT_HOME
D:\Users\84kure\.vagrant.d

$ setx VAGRANT_HOME "D:\Users\84kure\.vagrant.d"

$ echo $VAGRANT_HOME

D:\Users\84kure\.vagrant.d

[Git] Git Bashのホームディレクトリを変更する

2018年9月27日 @84kure

環境変数 HOME をセットすれば良い。

Git Bashを開く。

現在のホームディレクトリはCドライブにあったとして

$ pwd
/c/Users/84kure

1 2	$ pwd /c/Users/84kure

環境変数をセットすることでDドライブに変更することもできる。

$ setx HOME "D:\Users\84kure"
$ cd ~
$ pwd
/d/Users/84kure

$ setx HOME "D:\Users\84kure"

$ cd ~

$ pwd

/d/Users/84kure

[Laravel] カスタムバリデーションルール

例として、日本の郵便番号を 123-4567 という形式で入力させるバリデーションルールを定義する。
