Npm 我在安装angular cli时收到以下错误

我再次遇到angular cli问题（在mac上）。这是我的日志。我尝试卸载安装程序，但得到完全相同的错误。有什么建议吗？很可能是路径问题

您必须检查是否执行了npm--init，因为可能会发生这样的情况：您忘记初始化npm，并且根据错误的第5行，不存在package.json文件

如果不起作用，请尝试此npm安装npm@latest-g

如果这也不起作用，请尝试以下方法：

1. Ensure dependencies described correctly on package.json
2. Then type npm install and Enter.
3. Check issue still exists. and If issue not resolved, continue these 
   methods.
4. type npm cache clean and hit Enter
5. type sudo npm install -g npm and hit Enter.
6. Retry npm install and hit Enter.
