I think you missed this step:

我想你错过了这一步：

source ~/.nvm/nvm.sh

You can run this command on the bash OR you can put it in the file /.bashrc or ~/.profile or ~/.zshrc to automatically load it

您可以在 bash 上运行此命令，也可以将其放在文件 /.bashrc 或 ~/.profile 或 ~/.zshrc 中以自动加载它

Check your .bash_profile, .zshrc, or .profilefile. You most likely had a problem during the installation.

检查你的.bash_profile， .zshrc或.profile文件。您很可能在安装过​​程中遇到了问题。

You should have the following at the end of one of those files.

您应该在这些文件之一的末尾有以下内容。

[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh  # This loads NVM

The . $HOME/.nvm/nvm.shis the same as source $HOME/.nvm/nvm.sh

该. $HOME/.nvm/nvm.sh是一样的source $HOME/.nvm/nvm.sh

See: Sourcing a File

请参阅：获取文件

You can also check to see if you have a .nvmfolder.

您还可以检查是否有.nvm文件夹。

ls -a | grep .nvm

If you're missing that folder then the installation failed to run the git command. This could be due to being behind a proxy. Try running the following instead.

如果您缺少该文件夹，则安装无法运行 git 命令。这可能是由于在代理后面。尝试运行以下命令。

git clone http://github.com/creationix/nvm.git .nvm

This works for me:

这对我有用：

1. Before installing nvm, run this in terminal: touch ~/.bash_profile

2. After, run this in terminal:
   curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

3. Important...- DO NOT forget to Restartyour terminal ORuse command source ~/.nvm/nvm.sh(this will refresh the available commands in your system path).

4. In the terminal, use command nvm --versionand you should see the version

1. 在安装之前nvm，在终端中运行它：touch ~/.bash_profile

2. 之后，在终端中运行：
   curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash

3. 重要...- 不要忘记重新启动终端或使用命令source ~/.nvm/nvm.sh（这将刷新系统路径中的可用命令）。

4. 在终端中，使用命令nvm --version，您应该会看到版本

source ~/.nvm/nvm.shAdd this line to ~/.bashrc, ~/.profile, or ~/.zshrc

source ~/.nvm/nvm.sh将此行添加到 ~/.bashrc、~/.profile 或 ~/.zshrc

Quick answer

快速回答

Figure out the following:

弄清楚以下几点：

1. Which shell is your terminal using, type in: echo $0to find out (normally works)
2. Which start-up file does that shell load when starting up (NOT login shell starting file, the normal shell starting file, there is a difference!)
3. Add source ~/.nvm/nvm.shto that file (assuming that file exists at that location, it is the default install location)
4. Start a new terminal session
5. Profit?

1. 您的终端使用哪个 shell，输入：echo $0以找出（通常有效）
2. 启动时该shell加载哪个启动文件（不是登录shell启动文件，正常的shell启动文件，有区别！）
3. 添加source ~/.nvm/nvm.sh到该文件（假设该文件存在于该位置，则它是默认安装位置）
4. 开始一个新的终端会话
5. 利润？

Example

例子

As you can see it states zshand not bash.

正如你所看到的，它声明zsh而不是bash。

To fix this I needed to add source ~/.nvm/nvm.shto the ~/.zshrcfile as when starting a new terminal my Deepin Terminal zsh reads ~/.zshrcand not bashs ~/.bashrc.

为了解决这个问题，我需要在启动新终端时添加source ~/.nvm/nvm.sh到~/.zshrc文件中，我的深度终端 zsh 读取~/.zshrc而不是 bashs ~/.bashrc。

Why does this happen

为什么会发生这种情况

This happens because when installing NVM it adds code to ~/.bashrc, as my terminal Deepin Terminal uses zshand not bashit never reads ~/.bashrcand therefor never loads NVM.

这是因为安装NVM时，增加了代码~/.bashrc，作为我的终端Deepin终端使用zsh，而不是bash它从不读取~/.bashrc并为此从未负荷NVM。

In other words: this is NVMs fault.

换句话说：这是 NVM 的错误。

In macOS, i had to source it using source ~/.nvm/nvm.shcommand to fix this problem.

在 macOS 中，我不得不使用source ~/.nvm/nvm.sh命令来解决这个问题。

After that, add these lines

之后，添加这些行

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

onto ~/.bash_profileso that nvm will be sourced automatically upon login.

在~/.bash_profile使NVM将在登录后自动加载。

All answers to this questions are useful. Especially the answer given by Travis helped me. For Mac OS X users I would like to provide some steps which will help them to work with the fresh installation of Node Version Manager a.k.a. nvm.

这个问题的所有答案都是有用的。特别是特拉维斯给出的答案对我有帮助。对于 Mac OS X 用户，我想提供一些步骤来帮助他们使用 Node Version Manager aka nvm 的全新安装。

Installing & using nvm on Mac OS X

在 Mac OS X 上安装和使用 nvm

Here are the steps for fresh installation of nvm and using it without any issue:

以下是全新安装 nvm 并在没有任何问题的情况下使用它的步骤：

• Install homebrew from here.

• Using homebrew install nvm

  brew update brew install nvm

• Create .nvmdirectory at ~/.nvmlocation.

  mkdir ~/.nvm

• Now if you don't have .bash_profilefile setup for OS X terminal then please create a .bash_profileat the root level:

  nano ~/.bash_profile

• Paste below code in the .bash_profileand press CTRL + Oand press enter to save .bash_profilefile. Press CTRL + Xto exit from editor:

  export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

• Now either quite (CMD + Q) the terminal or run below command to load .bash_profilesettings:

  source ~/.bash_profile

• Now run nvm lscommand to get the list of all installed nodejs versions.

• 从这里安装自制软件。

• 使用自制软件安装 nvm

  brew update brew install nvm

• .nvm在~/.nvm位置创建目录。

  mkdir ~/.nvm

• 现在，如果您没有.bash_profile为 OS X 终端设置文件，请.bash_profile在根级别创建一个：

  nano ~/.bash_profile

• 将下面的代码粘贴到 中.bash_profile，然后CTRL + O按回车键保存.bash_profile文件。按CTRL + X退出编辑器：

  export NVM_DIR=~/.nvm source $(brew --prefix nvm)/nvm.sh

• 现在要么完全 ( CMD + Q) 终端或运行下面的命令来加载.bash_profile设置：

  source ~/.bash_profile

• 现在运行nvm ls命令以获取所有已安装 nodejs 版本的列表。

First add following lines in ~/.bashrc file

首先在 ~/.bashrc 文件中添加以下几行

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

then open terminal and source the nvm.sh script

然后打开终端并获取 nvm.sh 脚本

source ~/.nvm/nvm.sh

OSX 10.15.0 Catalina(released November 2019) changed the default shell to zsh.

OSX 10.15.0 Catalina（2019 年 11 月发布）将默认 shell 更改为 zsh。

The default shell was previously bash.

默认的 shell 以前是 bash。

The installation command given on the nvm GitHub pageneeds to be tweaked to include "zsh" at the end.

需要调整nvm GitHub 页面上给出的安装命令以在末尾包含“zsh”。

curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | zsh

Note: you might need to ensure the .rcfile for zsh is present beforehand:

注意：您可能需要.rc事先确保zsh的文件存在：

touch ~/.zsrhrc
