Making sure /usr/local/bin is in my $PATH on mac
提问by Kevin Russell
I've installed node.js for Macintosh using the lastest installer for Macintosh. I now want to check that /usr/local/bin is in my $PATH, as the installer instructed. I've opened up the Terminal application and researched help on the net, but I'm lost, as to how to accomplish the above, then start the node.js process. Can anyone clear this up? Thank you for very much.
我已经使用最新的 Macintosh 安装程序为 Macintosh 安装了 node.js。我现在想按照安装程序的指示检查 /usr/local/bin 是否在我的 $PATH 中。我已经打开终端应用程序并在网上研究了帮助，但我迷失了，至于如何完成上述操作，然后启动 node.js 进程。任何人都可以解决这个问题吗？非常感谢。

echo $PATHwill print your path. If you see /usr/local/binbetween some colons, then it's in your path.
echo $PATH将打印您的路径。如果您/usr/local/bin在一些冒号之间看到，那么它就在您的路径中。

open terminal and type the command below
打开终端并输入下面的命令
echo $PATH
You should see something like this
你应该看到这样的东西
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
the presence of /usr/local/binin the output means you are good to go
/usr/local/bin在输出中的存在意味着你很高兴
