🐛 Bug description

Describe your issue in detail.
wasm-pack download error

🤔 Expected Behavior

What should have happened?
I am beginner for Rust and Webassembly , I follow the Hello, World! to do

I am run

$ wasm-pack build

λ wasm-pack build
[INFO]: Checking for the Wasm target...
[INFO]: Compiling to Wasm...
warning: function is never used: `set_panic_hook`

To disable `wasm-opt`, add `wasm-opt = false` to your package metadata in your `Cargo.toml`.

My Internet is so bad that I want manually install binaryen-version_90-x86-windows.tar.gz
OS: Window10
Now I have binaryen-version_90-x86-windows.tar.gz

asm2wasm.exe
binaryen.dll
wasm-as.exe
wasm-ctor-eval.exe
wasm-dis.exe
wasm-emscripten-finalize.exe
wasm-metadce.exe
wasm-opt.exe
wasm-reduce.exe
wasm-shell.exe
wasm2js.exe

Where should I put in this file ?
And I try to wasm-pack again
It's will stop in

λ wasm-pack.exe build

I have the same problem.I download binaryen-version_90-x86-windows.tar.gz via web browser while I don't know where to install it.Can you share it with me? As for the problem you mentioned, it should not be a serious one.It just mean function set_panic_hook is not used. It just a tip for program optimization.

[WingDust]

By the way , wasm-pack don't generate package.json file so When I npm install

npm ERR! Could not install from "..\pkg" as it does not contain a package.json file.

And wasm-pack retry ,It's stop What I say above.

[asurance]

So, can you tell me where binaryen-version_90-x86-windows.tar.gz should be installed?

[WingDust]

@asurance open Assets find version_90 Assets and click

[asurance]

I know where to download and I had downloaded.I just don't know where to install.I tried C:\Users\***\.cargo\bin, but it took no effect.

[WingDust]

as same

[asurance]

I find it can be skipped by cargo install wasm-bindgen-cli.Maybe you can try too.

[WingDust]

@asurance

λ cargo install wasm-bindgen-cli
    Updating `https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git` index
error: binary `wasm-bindgen-test-runner.exe` already exists in destination
binary `wasm-bindgen.exe` already exists in destination
binary `wasm2es6js.exe` already exists in destination
Add --force to overwrite

don't work

[tafia]

I have the same error. For now I've disabled optimization by adding this in my Cargo.toml

[package.metadata.wasm-pack.profile.release]
wasm-opt = false

I hope someone give a proper answer.

[SebastienGllmt]

This issue is a duplicate of #886 I believe

[ZosoDerGoldene]

This issue is a duplicate of #886 I believe

I don't think so, because #886 was fixed/closed, but this problem persists

I met the same problem in Ubuntu 20.04 LTS.
Hope to find the way to solve it.
Here is my configuration:

• rustwasmc 0.1.29
• cargo 1.50.0 (f04e7fab7 2021-02-04)

This recently has started failing for me using Github Actions. The workarounds mentioned in #886 do not fix this, only disabling wasm-opt = false

Error: failed to download from https://github.com/WebAssembly/binaryen/releases/download/version_90/binaryen-version_90-x86-linux.tar.gz
To disable `wasm-opt`, add `wasm-opt = false` to your package metadata in your `Cargo.toml`.
Error: Process completed with exit code 1.

My current workaround is to manually download and run wasm-opt:

wget -O /tmp/binaryen-version_90-x86-linux.tar.gz  https://github.com/WebAssembly/binaryen/releases/download/version_90/binaryen-version_90-x86-linux.tar.gz
tar -xvf /tmp/binaryen-version_90-x86-linux.tar.gz -C /tmp
/tmp/binaryen-version_90/wasm-opt <file>.wasm -o <file>.wasm -Oz

[ghost]

replace dependency with the latest version wasm-bindgen = "0.2.78" works for me, i don`t know why

[hillin]

@asurance I'm not sure what went wrong on your side, but manually installing into C:\Users\<user-name>\.cargo\bin worked for me.

[1714080902120]

the lastest version 0.2.83 worked successfully.
change the dependence version from specifiy to 0.2, such as change 0.2.63 to 0.2

[Qix-]

@tafia do you happen to know how to set the metadata for Cargo workspaces in order to work around this?

[stash763]

The file seems to be truly missing from the location it is expecting to download it from . Running the following to install from source resolved the wasm-opt error:

cargo install wasm-bindgen-cli

[voidmozx]

Maybe you use npm/yarn install wasm-pack.

Just remove it and use cargo install instead.

yarn global remove wasm-pack
cargo install wasm-pack

[magicwenli]

This work for me(Macos):

wget -O /tmp/binaryen.tar.gz https://github.com/WebAssembly/binaryen/releases/download/version_111/binaryen-version_111-x86_64-macos.tar.gz
tar -xvf /tmp/binaryen.tar.gz -C /tmp
cp /tmp/binaryen-version_111/bin/wasm-opt ~/.cargo/bin/
cp -r /tmp/binaryen-version_111/lib ~/.cargo/
rm -rf /tmp/binaryen.tar.gz /tmp/binaryen-version_111/

wired，i can download the file by using browser, but clion just failed.

我也遇到了相同的问题，不过我已经解决了。
我的环境是windows，但是我想其他系统的解决方式应该差不多，因为我是在查看wasm-pack的源码时，发现的一个可行的处理办法。
如果你想知道具体源码是什么，建议自行前往并寻找，这并不复杂。
关键在于，wasm-pack在下载前，会使用 which::which("wasm-opt")查找相关的可执行文件位置。而which会在环境变量的PATH中进行寻找。
所以最后的解决办法很简单，在windows上，请把你下载的binaryen-version_90-x86-windows.tar.gz压缩包内的内容，放置到一个提前准备好wasm-opt的文件夹内，例如：D:\rust\binaryen\wasm-opt。

最后将这个路径加入系统环境变量PATH中：D:\rust\binaryen\wasm-opt\bin。

注意设置好环境变量后，需要重新打开一个新的命令控制台。

I had the same problem, but I already solved it.

My environment is Windows, but I think the solution for other systems should be similar, because I found a feasible solution when I was viewing the source code of wasm-pack.

If you want to know the specific source code, it is recommended to go and find it yourself, which is not complicated.

The key is that before downloading, wasm-pack will use which::which("wasm-opt") to find the location of the relevant executable file. And which will look in the PATH environment variable.

So the final solution is very simple, on Windows, please place the contents of the downloaded binaryen-version_90-x86-windows.tar.gz compressed package into a folder prepared in advance named wasm-opt, for example: D:\rust\binaryen\wasm-opt.

Finally, add this path to the system environment variable PATH: D:\rust\binaryen\wasm-opt\bin.

Note that after setting the environment variable, you need to reopen a new command console.

这个方法好使，我曾经想试试这种方法，但觉得不太可能是这样吧，就没有去试。。。。。

我先用一个空项目跑了一下witch相同逻辑的空项目，确实能拿到，就直接用了，然后一次成功。但是这个总是下载失败的问题是真的绷不住（host，VPN等等都试了），只能先这样解决了。

Maybe you use npm/yarn install wasm-pack.

Just remove it and use cargo install instead.

yarn global remove wasm-pack
cargo install wasm-pack

It does not work
