小ネタ：gemのexecutable directoryをPATHに追加したい

Posted at

homebrewを使ってrubyを更新すると、その都度gemのExecutableDirectoryをPATHに追加する必要があります。めんどくさいので手抜きします。

.zshrc
# =========
# Ruby(gem)
# =========
# Check "gem env" to EXECUTABLE DIRECTORY:
GEM_EXE_DIR=`gem env | grep "EXECUTABLE DIRECTORY" | awk '{print $4}'`
export PATH=$GEM_EXE_DIR:$PATH

gem envにExecutableDirectoryだけを出すオプションが欲しい。あったりするのかな？
