Question

我在Yosemite上，安装了Homebrew，Node和NPM。

Homebrew 0.9.5 节点v0.12.3 NPM 2.9.1

无论出于何种原因，我无法让Yeoman正确安装。安装似乎没问题，没有错误，但是当我检查确认安装时它不会给我--version，也不能执行你的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
> yodoctor

✔ 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文件显示为：

# 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"

我已经尝试首先通过Homebrew安装Node，然后发现了我无法解决的问题。 https://gist.github.com/DanHerbert/9520689

因为那不是我在终端中吹走所有东西，包括node，npm和homebrew。

现在我被卡住了，npm让我安装了grunt-cli，bower和yeoman的软件包，但是每当我尝试调用那些软件包时我都会：

-bash: yo: command not found

我假设它与/.bashrc内容有关，有人帮忙:(

我在优胜美地下遇到了同样的问题。

我的解决方案是：

sudo find /usr/local/ -name yo
/usr/local//Cellar/node/4.2.1/libexec/npm/bin/yo

打开$ HOME / .profile

export NODE_PATH="/usr/local/lib/node_modules"

export PATH="/usr/local/Cellar/node/4.2.1/libexec/npm/bin:$PATH"

export NODE_PATH=$NODE_PATH:/usr/local/Cellar/node/4.2.1/libexec/npm/lib/node_modules

打开新终端：

yo --version
1.4.8

也许你的节点版本是个问题。在安装'brew install node'之后开始我也是

node --version
v0.12.7

之后

brew update

并重新安装节点

node --version
v4.2.1

在Yosemite上安装Yeoman
