在mac上安装node.js和npm时遇到的困难

Question

我正在尝试在mac mini中安装node.js和npm。

我已经看过很多教程了。有时它会被安装，但无法使用。现在我正在使用Homebrew进行安装。

nbmacmini9:~ afsarunnisa$ brew install node
==> Downloading https://homebrew.bintray.com/bottles/node-0.12.7.yosemite.bottle
######################################################################## 100.0%
==> Pouring node-0.12.7.yosemite.bottle.tar.gz
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/man/man1/node.1
Target /usr/local/share/man/man1/node.1
already exists. You may want to remove it:
  rm '/usr/local/share/man/man1/node.1'

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

Possible conflicting files are:
/usr/local/share/man/man1/node.1
/usr/local/share/systemtap/tapset/node.stp
/usr/local/lib/dtrace/node.d
==> Caveats
Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
==> Summary
  /usr/local/Cellar/node/0.12.7: 2726 files, 31M
nbmacmini9:~ afsarunnisa$ node -v
-bash: node: command not found

无法检查是否安装了node。我再次尝试安装node.js，然后是这样的：

nbmacmini9:~ afsarunnisa$ brew install node
Warning: node-0.12.7 already installed, it's just not linked
nbmacmini9:~ afsarunnisa$ node -v
-bash: node: command not found
nbmacmini9:~ afsarunnisa$

你试过下面的步骤吗？

already exists. You may want to remove it:
  rm '/usr/local/share/man/man1/node.1'

首先删除上面的注释，然后重试。此外，对于mac，您可以直接从package安装节点。
