To upgrade Bun, run `bun upgrade`.
|
|
|
|
It automatically downloads the latest version of Bun and overwrites the currently-running version.
|
|
|
|
This works by checking the latest version of Bun in [bun-releases-for-updater](https://github.com/Jarred-Sumner/bun-releases-for-updater/releases) and unzipping it using the system-provided `unzip` library (so that Gatekeeper works on macOS)
|
|
|
|
If for any reason you run into issues, you can also use the curl install script:
|
|
|
|
```bash
|
|
$ curl https://bun.com/install | bash
|
|
```
|
|
|
|
It will still work when Bun is already installed.
|
|
|
|
Bun is distributed as a single binary file, so you can also do this manually:
|
|
|
|
- Download the latest version of Bun for your platform in [bun-releases-for-updater](https://github.com/Jarred-Sumner/bun-releases-for-updater/releases/latest) (`darwin` == macOS)
|
|
- Unzip the folder
|
|
- Move the `bun` binary to `~/.bun/bin` (or anywhere)
|
|
|
|
## `--canary`
|
|
|
|
[Canary](https://github.com/oven-sh/bun/releases/tag/canary) builds are generated on every commit.
|
|
|
|
To install a [canary](https://github.com/oven-sh/bun/releases/tag/canary) build of Bun, run:
|
|
|
|
```bash
|
|
$ bun upgrade --canary
|
|
```
|
|
|
|
This flag is not persistent (though that might change in the future). If you want to always run the canary build of Bun, set the `BUN_CANARY` environment variable to `1` in your shell's startup script.
|
|
|
|
This will download the release zip from https://github.com/oven-sh/bun/releases/tag/canary.
|
|
|
|
To revert to the latest published version of Bun, run:
|
|
|
|
```bash
|
|
$ bun upgrade
|
|
```
