当我尝试使用nvmi安装某些版本的节点时，我得到了这个消息我严格按照页面上的说明操作是行不通的。

您没有提供命令和您正在遵循的文档。NVM的安装非常简单。
(1/4)curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash确保您已经安装了curl。curl --version给了我7.68.0
(2/4)export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
(3/4)source ~/.bashrc获取终端中的nvm命令
您现在可以使用nvm命令了。
(4/4)nvm ls-remote用于检查可用版本，现在您可以明确选择要安装的版本，或者您可以使用nvm install 'lts/*'安装最新的lts版本
