问题 I'm new to npm and am trying to understand how recreating the node_modules directory for deployment works. We're using npm ci instead of npm install to ensure a clean slate during deployment. However, when we run it without any flags, we get the following error: Fix the upstream dependency conflict, or retry this command with --force, or --legacy-peer-deps to accept an incorrect (and potentially broken) dependency resolution.
