xcode 安装完后,兴匆匆的准备 gem install jekyll
,果然出了问题了。
$ gem install jekyll
Fetching: liquid-2.5.4.gem (100%)
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
嗯,我知晓只要 sudo
安装即可解决问题,可 Gentoo 下养成的洁癖不是说改就能改的啊,好吧,方法:
在 ~/.gemrc
文件中添加如下
all: --user-install
然后在 ~/.profile
中添加如下
# gem home
if [ -f /usr/bin/gem ]; then
export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH
fi
