mac|mac 安装node出现的问题 mac安装node出现的问题

mac通过brew安装完node 但是无法识别的问题
描述：在一次开发中，先通过brew install 安装完node，可以正常使用，这时候给卸载掉，又通过安装包进行安装。安装完以后，又卸载了，再通过brew安装。问题出现了，安装成功，但是node-v提示不识别node。

提示错误信息：

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 nodeTo 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.

解决运行下面代码，查看冲突

brew link --overwrite --dry-run node

下面的代码结果：

删除上面所有的冲突文件以后，执行下面代码。
brew link --overwrite node
如果还是继续报下面的错

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

执行赋予权限的代码：
chown -R mali:admin /usr/local/share/systemtap/
【mac|mac 安装node出现的问题】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
