每次运行ng命令时，它都会打印此警告：

As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release,
which will only support Node 6.9 and greater. This package will be officially deprecated
shortly after.

下面有关于禁用警告的说明，但没有关于用户应采取何种操作以切换到使用新包名的建议

我的第一个想法只是卸载并重新安装CLI，但所有文档都已更新，以引用新包，因此我无法计算出需要首先删除的旧包的名称

建议我只运行

npm安装-g@angular/cli@latest

，但这失败了：

npm ERR! code EEXIST
npm ERR! path ~/.nvm/versions/node/v15.14.0/bin/ng
npm ERR! EEXIST: file already exists
npm ERR! File exists: ~/.nvm/versions/node/v15.14.0/bin/ng
npm ERR! Remove the existing file and try again, or run npm
npm ERR! with --force to overwrite files recklessly.

在尝试安装时，是否有人可以建议我如何应对原始警告和此错误
