在mac上面安装appium---npm install时报错：npm WARN enoent ENOENT: no such file or directory,

> brew install node        # get node.js

> npm install -g appium  # get appium

> npm install wd          # get appium client

> appium &                # start appium

> node your-appium-test.js

1：npm command not found

curl -L http://npmjs.org/install.sh | sudo sh

2：npm install时报错：npm WARN enoent ENOENT: no such file ordirectory

The fix for me was : npm init --yes
