Question

当我使用命令wget或curl（OS X El Capitan 10.11.4）安装nvm时，控制台会打印

=> nvm is already installed in /Users/weichuang/.nvm, trying to update using git

=> 
=> Source string already in /Users/weichuang/.bashrc
npm ERR! error in /usr/local/lib/node_modules/love: ENOTDIR: not a directory, open '/usr/local/lib/node_modules/love/package.json'
npm ERR! missing: npmlog@, required by npm-registry-client@7.0.7
npm ERR! missing: prompt@^0.2.14, required by react-native-cli@0.1.4
=> You currently have modules installed globally with `npm`. These will no
=> longer be linked to the active version of Node when you install a new node
=> with `nvm`; and they may (depending on how you construct your `$PATH`)
=> override the binaries of modules installed with `nvm`:

/usr/local/lib
├── commander@2.9.0
├── cordova@5.3.3
├── download-cli@1.0.1
├── express@4.13.3
├── express-generator@4.13.1
├── forever@0.14.1
├── hexo@3.1.1
├── http-server@0.8.5

├── remem@1.0.3 -> /Users/weichuang/Desktop/rem/remem
├── showdown@1.2.3
├── supervisor@0.6.0
└── typescript@1.6.2

=> If you wish to uninstall them at a later point (or re-install them under your
=> `nvm` Nodes), you can remove them from the system Node as follows:

     $ nvm use system
     $ npm uninstall -g a_module

=> Close and reopen your terminal to start using nvm

虽然我关闭并重新打开我的终端以开始使用nvm，但问题仍然是// USER ACCOUNT ALREADY EXISTS \\ { // Stop the activity indicator. self.activityInd.stopAnimating() // Display an error message. let refreshAlert = UIAlertController(title: "USER DUPLICATION ERROR", message: "user account already exists, login as normal.", preferredStyle: UIAlertControllerStyle.Alert) refreshAlert.addAction(UIAlertAction(title: "Dismiss", style: .Default, handler: { (action: UIAlertAction!) in // Close the create user screen. self.dismissViewControllerAnimated(true, completion: nil) })) self.presentViewController(refreshAlert, animated: true, completion: nil) } })

Answer 1

输入终端

  source ~/.nvm/nvm.sh
  source ~/.profile
  source ~/.bashrc

Answer 2

我的回答是基于Mac OS X，但我确信它应该适用于其他基于Linux的系统。

安装＆amp;在Mac OS X上使用nvm

从here安装自制软件。
使用自制软件安装nvm

brew update brew install nvm
在.nvm位置创建~/.nvm目录。

mkdir ~/.nvm
现在，如果您没有为OS X终端设置.bash_profile文件，请在根级创建.bash_profile：

nano ~/.bash_profile
粘贴.bash_profile中的代码，然后按CTRL + O并按Enter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
现在要完全（CMD + Q）终端或运行以下命令来加载.bash_profile设置：

source ~/.bash_profile
现在运行nvm ls命令以获取所有已安装的nodejs版本的列表。

-bash：nvm：找不到命令
