I am using vagrant on a rails project. I' am checking to make sure that RVM is not globally installed and uninstalling RVM if it is with this script:
我在一个rails项目上使用流浪。我正在检查，以确保RVM不是全局安装和卸载的，如果它是用这个脚本:
if [-d "/usr/local/rvm"]; then
yes yes | sudo rvm implode
fi
I'm getting this error in output /tmp/vagrant-shell: line 15: [-d: command not found
我在输出/tmp/vagrant-shell中得到这个错误:第15行:[-d:命令未找到。
Why isn't -d working?
为什么不是- d工作吗?

The space between [ and -d is required, as [ is not special syntax, but a simple command name. As such, [-d is also a valid command name, but one that is unlikely to be found.
[和-d之间的空格是必需的，因为[不是特殊的语法，而是一个简单的命令名。因此，[-d也是一个有效的命令名，但不太可能找到。
