weex-toolkit是包括这些子命令 不过第一次使用子命令时会提示安装的 你只需要输入y即可，会自动安装 并自动维护后续的版本升级。
提示权限不对 一般就是你的node是root权限或者home目录没有写权限导致
首先不推荐用sudo 来安装weex-toolkit如果已经安装过了
建议 sudo chmod 777 ~/.xtoolkit （没有这个目录则先创建这个目录 mkdir -p ~/.xtoolkit
如果不能解决，请截图一下到底报什么错了~

我在weex debug xxx.we时遇到了类似问题，说下我的解决办法：
错误Log如下：（此刻路径是：/Users/pan/Documents/MyWork/WeexDemo/weex/src）

    at installer.(anonymous function).then (/usr/local/lib/node_modules/weex-toolkit/node_modules/xtoolkit/src/Command.js:49:31)

从上图错误可以看出，是/Users/pan/.xtoolkit/这个路径权限不够，执行了

sudo chmod -R 777 /Users/pan/.xtoolkit

命令，成功解决。

再次运行weex debug template.we可以看到

PandeMac:src pan$ weex debug template.we
