使用brew 安装 node 出现问题了

Question

使用brew安装node以后，node-v不显示版本号，whichnode没有显示，/usr/local/bin下也没有node
之前用这个命令把pkg的安装包删了sudorm-rf/usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man//node.}
然后用brew安装

Answer 1

按给出的提示操作一下alreadyexists.Youmaywanttoremoveit:rm'/usr/local/include/node/android-ifaddrs.h'Toforcethelinkandoverwriteallconflictingfiles:brewlink--overwritenodeTolistallfilesthatwouldbedeleted:brewlink--overwrite--dry-runnodebrew有移除指令,手工rm会残留很多配置和文件,下次安装的时候会出问题.

Answer 2

仔细看提示啊，发现真的很多人不看提示。很明显有一个库因为被你手动删掉，导致无法重新连接，所以无法连接node，下面甚至告诉你如果要强制连接node应该怎么做。
