Brew installs the older version of node

Brew Detailed: Http://stackoverflow.com/questions/3987683/homebrew-install-specific-version-of-formula
Finally I used the command:
1. View the current node version
$ Ls-l ' which node '
Lrwxr-xr-x 1 cyper admin, 12:09/usr/local/bin/node. /cellar/node/0.12.7/bin/node

2. View all versions that have been installed

$ ls/usr/local/cellar/node*
/usr/local/cellar/node:
0.12.7

/USR/LOCAL/CELLAR/NODE010:
0.10.40

3. View details of a node tag
$ Brew Info Node
or brew info node010

4. If you can find 0.10.40 node from the results of the second step, you can switch directly to the past
$ Brew Switch node010 0.10.40

4. If you have not previously installed version 0.10, you can view all available versions, from here you can find homebrew/versions/node010, which is the version I need to install later.
$brew Search Node

5. Direct installation prompts that you must first unlink the existing symbolic connection
$ Brew Unlink Node

6. After unlink, the installation begins to download and install.
$ Brew Install homebrew/versions/node010
==> installing node010 from Homebrew/homebrew-versions
==> Downloading https://homebrew.bintray.com/bottles-versions/node010-0.10.40.yosemite.bottle.tar.gz

7. View Node
$ node-v
0.10.40
