can you run bun install

[HuakunShen]

Does this mean I cannot dynamically import sentry?
JS doesn't have conditional build like rust. I didn't want to include both @sentry/bun and @sentry/node.
I am making another docker build with static import to see if it runs without installing packages on the fly.

[HuakunShen]

I tried again without dynamic import, but still it tries to install dependencies on start.

import * as SentryBun from "@sentry/bun"
import * as SentryNode from "@sentry/node"

export const Sentry = typeof Bun !== "undefined" ? SentryBun : SentryNode

[HuakunShen]

I tried eliminating all code related to sentry, and it seems to not have the problem again.
Maybe sentry itself is dynamically importing some packages?

But what if I do need sentry in my project?
If I use --no-install, will there be a problem?

[Jarred-Sumner]

--no-install is fine

it doesn't sit right with me that we are automatically installing dependencies by default in bundled code is all.

[HuakunShen]

so is this the expected behavior of bun or will this be changed in the future?
I will test if sentry will behave properly with —no-install
