如何用Homebrew的节点替换我的node版本？
我已安装此版本的节点
localhost:pplsi.accounts davea$ node -v
v10.16.3
localhost:mydir davea$ which node
/usr/local/bin/node
我更喜欢使用自制版本，所以我尝试了
localhost:mydir davea$ brew upgrade node

但是我的节点仍然显示为旧版本

如何用已安装的自制软件替换节点？
回答如下：可能是brew安装的节点不在路径中，将/ usr / local / bin文件夹添加到路径并尝试。
export PATH="/usr/local/bin:$PATH"
