我正在尝试使用 nvm 在运行macOS Sierra的mac上安装 node.js 但在我尝试运行时安装nvm之后
nvm install node它说Version 'node' not found - try nvm ls-remote to browse available versions.
当我运行nvm ls-remote时，我只获取 io.js 的列表，而不是节点。
nvm现在支持节点安装还是仅支持io.js？ 请帮我搞清楚，或者我应该选择标准的软件包安装程序。

我怀疑你的启动文件中没有nvm脚本。希望这可以帮助。 首先确保安装了基本的Node.js版本。
# create our array for demonstration
In [1]: s = [i for i in range(10)]
In [2]: s
Out[2]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
In [3]: s[2:] # from index 2 to last index
Out[3]: [2, 3, 4, 5, 6, 7, 8, 9]
In [4]: s[:8] # from index 0 up to index 8
Out[4]: [0, 1, 2, 3, 4, 5, 6, 7]
In [5]: s[4:7] # from index 4(included) up to index 7(excluded)
Out[5]: [4, 5, 6]
In [6]: s[:-2] # up to second last index(negative index)
Out[6]: [0, 1, 2, 3, 4, 5, 6, 7]
In [7]: s[-2:] # from second last index(negative index)
Out[7]: [8, 9]
In [8]: s[::-1] # from last to first in reverse order(negative step)
Out[8]: [9, 8, 7, 6, 5, 4, 3, 2, 1, 0]
In [9]: s[::-2] # all odd numbers in reversed order
Out[9]: [9, 7, 5, 3, 1]
In [11]: s[-2::-2] # all even numbers in reversed order
Out[11]: [8, 6, 4, 2, 0]
In [12]: s[3:15] # end is out of range, python will set it to len(s)
Out[12]: [3, 4, 5, 6, 7, 8, 9]
In [14]: s[5:1] # start > end, return empty list
Out[14]: []
In [15]: s[11] # access index 11(greater than len(s)) will raise IndexError

这将为您提供最新的稳定Node.js版本。您现在可以使用brew install node
继续安装NVM。另请记住，假设您正在使用zsh
curl or wget文件中
~/.zshrc成功设置export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm
NVM如果全部失败，您也可以使用N: Node Version Manager
