Node already installed, it's just not linked
提问by Ela
I tried to fix the error where you have to use sudo when running npm. I blindly followed a link to uninstall node, the code was from this gist
我试图修复运行 npm 时必须使用 sudo 的错误。我盲目地按照链接卸载节点，代码来自这个要点
After running the command and I tried to install it back with brew: brew install node. Which gave me the following error:
运行命令后，我尝试使用 brew: 重新安装它brew install node。这给了我以下错误：
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/doc/node/gdbinit
/usr/local/share/doc/node is not writable.
You can try again using:
brew link node
Trying to run brew link node, I got:
试图运行brew link node，我得到：
Linking /usr/local/Cellar/node/5.4.0...
Error: Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.
Then when I write brew install npm, I get:
然后当我写brew install npm，我得到：
Warning: node-5.4.0 already installed, it's just not linked
When I write npm -vI get:

Any ideas on how to solve this?

I managed to fix this by first running sudo chown -R $USER /usr/localand following it with brew link node. Now I have node properly installed.
我设法通过首先运行sudo chown -R $USER /usr/local并使用brew link node. 现在我已经正确安装了节点。

If you are on High Sierra, then sudo chown -R $USER /usr/localwon't work. Instead use:
如果您在 High Sierra 上，则sudo chown -R $USER /usr/local无法使用。而是使用：
sudo chown -R $(whoami) $(brew --prefix)/*

Extra step: run brew doctor for cleaning purpose

You might need to prune some extra old stuff if doctor find it.

You have to allow it to be overwritten. Whatever directory is not writable
您必须允许它被覆盖。任何目录都不可写
For example, if its /usr/lib/dtrace
例如，如果它的 /usr/lib/dtrace
sudo chown -R `whoami`:admin /usr/lib/dtrace
And then
进而
brew link --overwrite node
Fixes it
修复它

回答by SylvesterAbreuLoreto
I did have the same issue when I was brew link jqbut refering to /usr/local/lib is not writable. In one of my machines I couldn't apply Ela suggestion.
I did sudo chmod 776 /usr/local/libthen I did brew link jqwhich was successful and then changed it back to sudo chmod 755 /usr/local/lib.
我确实遇到了同样的问题，brew link jq但参考/usr/local/lib is not writable. 在我的一台机器上，我无法应用 Ela 的建议。我做到了sudo chmod 776 /usr/local/lib然后我做到了brew link jq，这是成功的，然后将其改回sudo chmod 755 /usr/local/lib.

In this case, Apparently you're struggling with 2 versions in your machine and You should link pointer to the right version, Try installing again node and Unlink the previous version and Link the new one.
在这种情况下，显然您的机器中存在 2 个版本，您应该将指针链接到正确的版本，尝试再次安装节点并取消链接先前版本并链接新版本。
brew install node
brew link --overwrite node
//If it already linked
brew unlink node && brew link node
