| """Simple script to download the pinned Node modules from GCS. |
| |
| This script exists because the node_modules archive currently contains |
| a node_modules/.bin directory with a bunch of symlinked files in it, |
| and download_from_google_storage.py won't let you have archives with |
| symlinks. |
| |
| In theory we should probably rebuild the node_modules distro without |
| the ./bin directory (using `npm install --no-bin-lnks`) but that would |
| cause the build scripts to fail and we'd have to replace `npmw` with |
| something else. |
