Installation FAQs

How do I fix npm "EACCES: permission denied" during global install?

expand_more

Never run npm with sudo. Instead, configure npm's global prefix in your home directory:
mkdir ~/.npm-global && npm config set prefix '~/.npm-global' Then add export PATH=~/.npm-global/bin:$PATH to your ~/.zshrc or ~/.bashrc.

How does LEGECY CLI protect my master API keys?

expand_more

Master OpenAI, Anthropic, and DeepSeek keys never touch developer workstations or the CLI binary. All code completions route through our sovereign reverse proxy gateway, keeping client binaries 100% immune to decompilation and key scraping.

How do I upgrade to the newest release?

expand_more

Simply run legecy update or re-run npm install -g @legecy/cli@latest. Your stored credentials in ~/.legecy/credentials.json remain intact.
