wasm-pack build hangs with no output for over 3 minutes

[jameshfisher]

🐛 Bug description

I ran the following:

$ wasm-pack build

It hung, and I left it for long enough to decide that it was a bug. I then ran it again and left it long enough to write out half of this bug report, before it miraculously eventually did something:

$ wasm-pack build
[INFO]: 🎯  Checking for the Wasm target...
...

It took at least 3 minutes to print something.

🤔 Expected Behavior

It should tell me what it's doing, and give some indication that it's not stuck in an infinite loop. I imagine you're losing many first-timer users who just assume this tool is broken, Ctrl-C, and move on.

👟 Steps to reproduce

Follow the quickstart until step 5.

I'm also having this issue, but I don't even get as far as the initial [INFO], I'm getting no output whatsoever

environment:
wasm-pack version: 0.11.1
rustc version: 1.60.0
windows

Please try out v0.12.0 from one of the following ways:

• https://github.com/rustwasm/wasm-pack/releases/tag/v0.12.0
• https://crates.io/crates/wasm-pack/0.12.0
• https://www.npmjs.com/package/wasm-pack/v/0.12.0

Okey, I found that's probably a network issue. After downloading wasm32-unknown-unknown target the problem disappeared.

I was just following this page here: https://developer.mozilla.org/en-US/docs/WebAssembly/Rust_to_Wasm

I just had wasm-pack build --target web hang on me for over 30 minutes.

I was under the impression this would take a long time because of this:
https://developer.mozilla.org/en-US/docs/WebAssembly/Rust_to_Wasm#building_the_package

I went searching and came here.
Went here and installed: https://rustwasm.github.io/wasm-pack/installer/
(I already had it installed though from the Mozilla doc I was reading)
Reinstalled it

Ran wasm-pack build --target web again and ran instantly.

OS: Windows
wasm-bindgen = "0.2.92"
rustc 1.79.0 (129f3b996 2024-06-10)

I'm having this problem. I've verified that target wasm32-unknown-unknown is installed, and I tried using wasm-pack installer from the website, so the solutions in #1231 (comment) and #1231 (comment) didn't apply. I've tried disabling wasm-opt as described in #921. No amount of --verbose, or --log-level flags seem to cause it to generate any messages indicating that it's doing anything.

Arch Linux
wasm-pack 0.13.0
wasm-bindgen 0.2.95
rustup 1.27.1
rustc 1.81.0

Edit: It finally did output some information after many minutes, and did run successfully. After this first time, it starts up quickly on concurrent runs.
