mac通過(guò)brew安裝完node 但是無(wú)法識(shí)別的問(wèn)題

描述：

在一次開(kāi)發(fā)中，先通過(guò)brew install 安裝完node，可以正常使用，這時(shí)候給卸載掉，又通過(guò)安裝包進(jìn)行安裝。安裝完以后，又卸載了，再通過(guò)brew安裝。問(wèn)題出現(xiàn)了，安裝成功，但是node-v提示不識(shí)別node。

提示錯(cuò)誤信息：

Linking /usr/local/Cellar/node/11.2.0...
Error: Could not symlink include/node/common.gypi
Target /usr/local/include/node/common.gypi
already exists. You may want to remove it:
  rm '/usr/local/include/node/common.gypi'

To force the link and overwrite all conflicting files:
  brew link --overwrite node

To list all files that would be deleted:
  brew link --overwrite --dry-run node
localhost:wkdir meng$ brew link --overwrite node
Linking /usr/local/Cellar/node/11.2.0...
Error: Could not symlink include/node/common.gypi
/usr/local/include/node is not writable.

解決

運(yùn)行下面代碼，查看沖突

brew link --overwrite --dry-run node

下面的代碼結(jié)果：

刪除上面所有的沖突文件以后，執(zhí)行下面代碼。

brew link --overwrite node

如果還是繼續(xù)報(bào)下面的錯(cuò)

Error: Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.

執(zhí)行賦予權(quán)限的代碼：

chown -R mali:admin /usr/local/share/systemtap/

然后就搞定了：

malideMacBook-Pro:bin mali$ brew link --overwrite node
Linking /usr/local/Cellar/node/12.12.0... 7 symlinks created
malideMacBook-Pro:bin mali$ node -v
v12.12.0
