## For Contributors ### Improving Documentation - [x] Run `pnpm prettier-fix` to fix formatting issues before opening the PR. - [x] Read the Docs Contribution Guide to ensure your contribution follows the docs guidelines: https://nextjs.org/docs/community/contribution-guide ### What? Add instructions for using `bun/bunx` where relevant. I only added mentions where npm/yarn/pnpm were all already listed. ### Why Bun can be used as a runtime-agnostic [package manager](https://bun.sh/package-manager) and script runner in any project with a `package.json`. (Sorry, I probably should have consolidated this with https://github.com/vercel/next.js/pull/53467) Co-authored-by: Steven <229881+styfle@users.noreply.github.com>

title: Sharp Missing In Production
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
The `next/image` component's default loader uses [`squoosh`](https://www.npmjs.com/package/@squoosh/lib) because it is quick to install and suitable for a development environment.
|
|
|
|
- For a production environment using `next start`, it is strongly recommended you install [`sharp`](https://www.npmjs.com/package/sharp).
|
|
|
|
You are seeing this error because Image Optimization in production mode (`next start`) was detected.
|
|
|
|
- For a production environment using `output: "standalone"`, you must install [`sharp`](https://www.npmjs.com/package/sharp).
|
|
|
|
You are seeing this error because Image Optimization in standalone mode (`output: "standalone"`) was detected.

|
## Possible Ways to Fix It
|
|
|
|
- Install `sharp` by running one of the following commands in your project directory:
|
|
|
|
```bash filename="Terminal"
|
|
npm i sharp
|
|
```
|
|
|
|
```bash filename="Terminal"
|
|
yarn add sharp
|
|
```
|
|
|
|
```bash filename="Terminal"
|
|
pnpm add sharp
|
|
```
|
|
|
|
```bash filename="Terminal"
|
|
bun add sharp
|
|
```
|
|
|
|
Then, build your project with `next build`. Finally, restart the server with either `next start` for production mode or `node server.js` for standalone mode.
|
|
|
|
- If `sharp` is already installed but can't be resolved, set the `NEXT_SHARP_PATH` environment variable such as `export NEXT_SHARP_PATH=/tmp/node_modules/sharp`. Then, build your project with `next build`. Finally, restart the server with either `next start` for production mode or `node server.js` for standalone mode.
|
|
|
|
> Note: This is not necessary for Vercel deployments, since `sharp` is installed automatically for you.
