Check your .bash_profile or .profile file. You most likely had a problem during the installation.

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

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

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

See: Sourcing a File

You can also check to see if you have a .nvm folder.

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.

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

检查您的配置文件。bash_profile或。你最有可能在安装过程中有问题。

在这些文件的结尾处应该有以下内容。

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

这个.家/美元。NVM / nvm.sh是源家/美元一样。NVM / nvm.sh

参见：采购文件

你也可以检查看看，如果你有一个NVM文件夹。

ls -a | grep .nvm

如果你错过了那个文件夹然后安装运行git命令。这可能是由于背后的代理。尝试运行以下。

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

I think you missed this step:

source ~/.nvm/nvm.sh

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

https://github.com/creationix/nvm

我想你错过了这一步：

source ~/.nvm/nvm.sh

你可以运行这个命令的bash或者你可以把它放在文件.bashrc或~ /轮廓自动加载它。

https://github.com/creationix/nvm

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

源~ /。NVM / nvm.sh这一行添加到~ / .bashrc，~ /轮廓，或~ / .zshrc

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

After that, add these lines

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

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

在MacOS，我不得不源使用源~ /。NVM / nvm.sh命令来解决这个问题。

之后，添加这些行

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

在~ /。bash_profile使NVM将源时自动登录。

Not directly connected to the question, but there is a similar problem that may happen, take a look at this question: Can't execute nvm from new bash

Here's my answer on that post, just for the reference:

If you are running from a new bash instance, and you HAVE the initialization code at your ~/.bashrc, ~/.bash_profile, etc, then you need to check this initialization file for conditionals.

On Ubuntu 14, there is a:

case $- in
    *i*) ;;
      *) return;;
esac

At line 6, that will halt it's execution if bash is not being ran with the "-i" (interactive) flag. So you would need to run:

bash -i

Also, at the end of the file, there is a

[ -z "$PS1" ] && return

That will halt it's execution if not being ran with $PS1 set (like on a remote ssh session).

If you do not wish to add any env vars or flags, you will need to remove those conditionals from your initialization file.

Hope that's helpful.

不直接相连的问题，但也存在类似的问题，可能会发生，去看待这一问题：不能从新的bash执行NVM

这是我在那篇文章上的回答，只是为了参考：

如果你是从一个新的攻击实例运行，和你的初始化代码在你的~ / .bashrc，~ /。bash_profile，等等，那么你需要检查这个初始化文件的条件。

在Ubuntu 14中，有一个：

case $- in
    *i*) ;;
      *) return;;
esac

在6号线，如果bash不是跑“我”停止它的执行（互动）的旗帜。所以你需要运行：

bash -i

此外，在文件的结尾，有一个

[ -z "$PS1" ] && return

那如果不跑1美元停止它的执行（如设置在远程SSH会话）。

如果你不想添加任何env vars或标志，你需要从你的初始化文件中删除这些条件。

希望有帮助。

If you are using OS X, you might have to create your .bash_profile file before running the installation command. That did it for me.

Create the profile file

touch ~/.bash_profile

Re-run the install and you'll see a relevant line in the output this time.

=> Appending source string to /Users/{username}/.bash_profile

Reload your profile (or close/re-open the Terminal window).

.  ~/.bash_profile

如果你使用的是Mac OS X，你可以建立你的。bash_profile文件运行安装命令之前。那是为我做的。

创建配置文件

touch ~/.bash_profile

重新运行安装，你会看到一个相关的输出在这一次。

= & gt；添加源字符串/用户/ {用户名} /。bash_profile

重新加载您的配置文件（或关闭/重新打开终端窗口）。

.  ~/.bash_profile
