BASH 3.2.25 required (you have 4.3.18(1)-release)
Bash 以前是Mac OS X 10.9.4
附带的默认设置。 我已将其升级为version 4.3.18(1)-release (x86_64-apple-darwin13.2.0)
,但错误仍然存在。
如果有的话,安装肯定应该更优雅地失败。
解决方法:
curl -Lk get.rvm.io -o rvm-installer
chmod +x rvm-installer
./rvm-installer
rvm
可用: source /Users/[username]/.rvm/scripts/rvm
你能比较:
$ printf "1\n2\n" | \head -n1
1
对比
$ printf "1\n2\n" | \command \head -n1
1
