Warning: node-7.4.0 already installed, it's just not linked

mac筆記本卸載／安裝node

1.nodejs在Mac下的卸載:

在終端輸入以下命令：

sudo rm -rf /usr/local/{bin/{node,npm},lib/node_modules/npm,lib/node,share/man//node.}

2.安裝node

brew install node
Warning: node-5.0.0 already installed, it's just not linked

  1. You should be able to run:

brew link node

What you're doing is telling Brew to create a symlink for the node executable to the /usr/bin (or /usr/local/bin) directory, as far as I am aware.

but...

Linking /usr/local/Cellar/node/7.4.0...
Error: Could not symlink share/doc/node/gdbinit
/usr/local/share/doc/node is not writable.

  1. Try "sudo chown -R $(whoami):admin /usr/local" worked for me.
