节点v12.13.1
重现此问题的步骤
首先，我尝试安装Polymer cli。 我在终端输入以下内容
npm install -g凉亭 安装Polymer CLI。 须藤npm install -g polymer-cli
会出现这样的错误

并添加--unsafe-perm进行安装
npm install -g bower --unsafe-perm
安装Polymer CLI。
sudo npm install -g polymer-cli --unsafe-perm
nb：不出现--unsafe-perm错误
所以我可以在终端中键入聚合物并显示所有这样的命令 succes install polymer cli in terminal
完成检查聚合物的安装后，我尝试启动一个项目 mkdir polymer-admin或polymeradmin cd聚合物管理员或聚合物管理员 聚合物初始 并在下面显示这样的选项
当我在聚合物初始化中选择一个选项时 错误发生
error when choosing one of all-polymer init options
我的问题是如何解决这个问题？
