## Problem

If you're getting this kind of error when running Node.js programs with binary dependencies that don't support M1 yet, e.g.:

```sh
$ yarn test
dyld[51175]: missing symbol called
dyld[51176]: missing symbol called
```

## Solution

tl;dr: (Re)install a x64 build of Node.js.

### Steps to follow

1. Start a new shell using Rosetta2
   ```sh
   $ arch -x86_64 zsh
   ```
   
2. In that shell, reinstall the `x64` version of Node.js
   ```sh
   $ nvm use system
   $ nvm cache clear
   $ nvm uninstall 16 # or the version you need
   $ nvm install 16   # or the version you need
   $ nvm use 16       # or the version you need
   ```
   
3. Still in that shell, reinstall and build npm dependencies from scratch
   ```sh
   $ rm -rf node_modules
   $ yarn cache clean
   $ yarn install
   ```

4. Whenever you come back to your project (e.g. after restarting), don't forget to select that same version of Node.js!
    ```sh
    $ nvm use 16 # or the one you installed in step 2
    ```
    
### Troubleshooting

If you still see the error:

- Try (re)installing your dependencies with `npm install` instead of `yarn install`.

- It could be that the `node` command is not linked to `nvm`.
  - To check that, run `nvm use 16; nvm ls` and check that the little arrow (`->`) targets `v16`.
  - If it targets `system`, you may want to uninstall any other installation of `node` (e.g. `which node; brew uninstall node`), then retry the whole procedure.
