【问题描述】：
我在 Yosemite 上，安装了 Homebrew、Node 和 NPM。
自制 0.9.5 节点 v0.12.3 NPM 2.9.1
无论出于何种原因，我都无法让 Yeoman 正确安装。安装似乎很顺利，没有错误，但是当我检查以确认安装时，它不会给我--version，也不能执行 yo 功能...
Gregs-MacBook-Pro:~ G$ npm install -g yo
/Users/G/npm/bin/yo -> /Users/G/npm/lib/node_modules/yo/lib/cli.js
> yo@1.4.6 postinstall /Users/G/npm/lib/node_modules/yo

Yeoman Doctor
Running sanity checks on your system
✔ Global configuration file is valid
✔ No .bowerrc file in home directory
✔ No .yo-rc.json file in home directory
✔ NODE_PATH matches the npm root
Everything looks all right!

Gregs-MacBook-Pro:~ G$ yo -v
-bash: yo: command not found
我已经打开了 .bashrc（必须使用 sudo 才能打开 + 保存它）。没有 sudo 我无法保存更改。
sudo nano /.bashrc
bashrc 文件内容为：
# NPM packages in homedir
NPM_PACKAGES="$HOME/.npm-packages"
# Tell our environment about user-installed node tools
PATH="$NPM_PACKAGES/bin:$PATH"
# Unset manpath so we can inherit from /etc/manpath via the `manpath` command
unset MANPATH # delete if you already modified MANPATH elsewhere in your configuration
MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
# Tell Node about these packages
NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"
我首先尝试通过 Homebrew 安装 Node，然后发现了这个我也无法解决的问题。 https://gist.github.com/DanHerbert/9520689
因为我没有把终端中的所有东西都吹走，包括节点、npm 和自制软件。
现在我被卡住了，npm 让我安装包 grunt-cli、bower 和 yeoman，但任何时候我尝试调用这些包时都会得到：
-bash: yo: command not found
我假设它与 /.bashrc 内容有关，有人帮忙:(
【问题讨论】：
-
在
OS X中，您应该将导出内容放入~/.bash_profile，然后退出并重新启动Terminal。 -
尝试将此添加到 ~/.bash_profile 并重新启动。
echo export PATH=\"\$PATH\":~/.node/bin >> ~/.bash_profile运气不好：/ -
在终端尝试命令
which yo或which yeoman，有什么出现吗？ -
两者都没有。
-
如果你做
ls /usr/local/share/npm/bin/ | grep yo，它输出“yo”然后尝试创建一个符号链接ln -s /sbin/ /usr/local/share/npm/bin/yo
