### Install & Update Script
|

To **install** or **update** nvm, you should run the [install script][2]. To do that, you may either download and run the script manually, or use the following cURL or Wget command:

#### Additional Notes
|
||||
|

**Note:** You can add `--no-use` to the end of the above script (...`nvm.sh --no-use`) to postpone using `nvm` until you manually [`use`](#usage) it.
|

- If the environment variable `$XDG_CONFIG_HOME` is present, it will place the `nvm` files there.</sub>
|

Eg: `curl ... | NVM_DIR="path/to/nvm"`. Ensure that the `NVM_DIR` does not contain a trailing slash.

**Note:** On Linux, after running the install script, if you get `nvm: command not found` or see no feedback from your terminal after you type `command -v nvm`, simply close your current terminal, open a new terminal, and try verifying again.
|

#### Troubleshooting on Linux
|

|

**Note:** Since OS X 10.9, `/usr/bin/git` has been preset by Xcode command line tools, which means we can't properly detect if Git is installed or not. You need to manually install the Xcode command line tools before running the install script, otherwise, it'll fail. (see [#1782](https://github.com/nvm-sh/nvm/issues/1782))

#### Troubleshooting on macOS
|
||||
|
||||

You need to manually install the Xcode command line tools before running the install script, otherwise, it'll fail. (see [#1782](https://github.com/nvm-sh/nvm/issues/1782))
|
||||
|
||||
If you get `nvm: command not found` after running the install script, one of the following might be the reason:
|
||||
|
||||
- Your system may not have a `.bash_profile` file where the command is set up. Create one with `touch ~/.bash_profile` and run the install script again
|
||||
|
||||
- You might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry.
|
||||
|
||||
If the above doesn't fix the problem, you may try the following:
|
||||
- Open your `.bash_profile` (or `~/.zshrc`, `~/.profile`, or `~/.bashrc`) and add the following line of code: `source ~/<your_profile_file>`. E.g. `source ~/.bashrc` or `source ~/.zshrc`.
|
||||
- If the above doesn't work, try adding the [snippet from the install section](#profile_snippet) that finds the correct nvm directory and loads nvm, to your profile (`~/.bash_profile`, `~/.zshrc`, `~/.profile`, or `~/.bashrc`).

||||

|
||||
- If you use bash, it may be that your `.bash_profile` (or `~/.profile`) does not source your `~/.bashrc` properly. You could fix this by adding `source ~/<your_profile_file>` to it or follow the next step below.

Any time your local copy of `nvm` connects to https://nodejs.org, it will re-create the appropriate local aliases for all available LTS lines. These aliases (stored under `$NVM_DIR/alias/lts`), are managed by `nvm`, and you should not modify, remove, or create these files - expect your changes to be undone, and expect meddling with these files to cause bugs that will likely not be supported.
