How to: Environment variables
nvm exposes the following environment variables:

- `NVM_DIR` - nvm's installation directory.
- `NVM_BIN` - where node, npm, and global packages for the active version of node are installed.
- `NVM_INC` - node's include file directory (useful for building C/C++ addons for node).
- `NVM_CD_FLAGS` - used to maintain compatibility with zsh.
- `NVM_RC_VERSION` - version from .nvmrc file if being used.

Additionally, nvm modifies `PATH`, and, if present, `MANPATH` and `NODE_PATH` when changing versions.
