- You can instruct the installer to not edit your shell config (for example if you already get completions via a [zsh nvm plugin](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/nvm)) by setting `PROFILE=/dev/null` before running the `install.sh` script. Here's an example one-line command to do that: `PROFILE=/dev/null bash -c 'curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash'`
#### Installing in Docker
When invoking bash as a non-interactive shell, like in a Docker container, none of the regular profile files are sourced. In order to use `nvm`, `node`, and `npm` like normal, you can instead specify the special `BASH_ENV` variable, which bash sources when invoked non-interactively.
```Dockerfile
# Use bash for the shell
SHELL ["/bin/bash", "-o", "pipefail", "-c"]
# Create a script file sourced by both interactive and non-interactive bash shells
ENV BASH_ENV /home/user/.bash_env
RUN touch "${BASH_ENV}"
RUN echo '. "${BASH_ENV}"' >> ~/.bashrc
# Download and install nvm
RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | PROFILE="${BASH_ENV}" bash
RUN echo node > .nvmrc
RUN nvm install
```
#### Troubleshooting on Linux
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.
