[Workers Build] bun: not found error

Cloudflare Workers is deployed using the build function. The project uses Bun, and the build process runs bun install --frozen-lockfile, although I have not specifically configured the build. I am getting the following error here, which prevents me from deploying. Deployment was successful until 21 hours ago, but now it is failing. Please help. Below is the build log.

So I am wondering if simply bun is being removed from the build server.

@Maximo @Walshy | Deploying Thank you for your prompt response! Once I had solved the problem with the following steps. Please refer to it! 1. fix BUN_VERSION in the build variable to 1.1.0 2. execute the following shell in the build command
#! /bin/bash
# ! !work around!
curl -fsSL https://bun.sh/install | bash
export BUN_INSTALL="$HOME/.bun”
export PATH="$BUN_INSTALL/bin:$PATH”
bun --version

bun install
#! /bin/bash
# ! !work around!
curl -fsSL https://bun.sh/install | bash
export BUN_INSTALL="$HOME/.bun”
export PATH="$BUN_INSTALL/bin:$PATH”
bun --version

bun install
3. push to the linked branch on github and execute build I confirmed that it was cured! Thank you!
