bash - 安装 Node 时，我收到有关我的路径的提示

Question

提示

Node was installed at

   /usr/local/bin/node

npm was installed at

   /usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

我如何判断它是否在我的路径中？

bash简介

export PATH=$PATH:/Users/anderskitson/bin

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

export PATH="/usr/local/mysql/bin:$PATH"

#navigate to tech basics theme
alias techbasics='cd /Users/anderskitson/sites/techbasics/wp-content/themes/techBasicsCustom ; subl . '

这是我的 echo

Anderss-iMac:~ anderskitson$ echo $PATH
/usr/local/mysql/bin:/Users/anderskitson/.rbenv/shims:/Users/anderskitson/.rbenv/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/anderskitson/bin

Answer 1

How do I tell if it is in my path?

根据提示:

echo $PATH | tr ':' '\n' | grep '^/usr/local/bin$'

如果您看到 /usr/local/bin，那么它就在您的 $PATH 中。

如果它不存在(如果它不存在我会感到惊讶):您需要将以下内容添加到您的 Bash 配置文件中:

export PATH="/usr/local/bin:${PATH}"

...然后获取您的 Bash 配置文件或启动新的 shell session 。
