Installing pnpm on Ubuntu (Safe Methods)

pnpm and npm coexist safely — nothing breaks, existing node_modules untouched.

Recommended: Corepack (Node.js ≥16.13)

node -v              # confirm ≥16.13
corepack enable
corepack prepare pnpm@latest --activate
pnpm -v

Alternative: via npm

npm install -g pnpm
pnpm -v

After install (good practice)

pnpm setup           # sets global bin path
source ~/.bashrc

Avoid (less controlled)

curl -fsSL https://get.pnpm.io/install.sh | sh -   # modifies shell configs

Notes

• pnpm uses its own store at ~/.pnpm-store
• No impact on global npm packages
• Excellent monorepo support (vs npm's basic support)
• Faster and lower disk usage than npm (uses symlinks)
