[英]Rust web assembly fails to build with openssl error
I am fairly new to rust and I build a web assembly project using it, am using openssl package in the project.我对 rust 相当陌生,我使用它构建了一个 web 装配项目,我在项目中使用 openssl ZEFE90A8E604A7C8B70E88。 Now the problem comes when I want to build the app, it fails with the following output:
现在问题来了,当我想构建应用程序时,它失败了,出现以下 output:
[INFO]: Checking for the Wasm target...
[INFO]: Compiling to Wasm...

I have tried every solution in the internet, installed libssldev
, pkg-config
, I also reinstalled openssl
in my machine several times, still no fruits.我已经尝试了互联网上的所有解决方案,安装了
libssldev
, pkg-config
,我还在我的机器上重新安装openssl
几次,仍然没有结果。 I have debugged this for hours without any success.我已经调试了几个小时没有任何成功。
The following is my Cargo.toml

。 Any help would be highly appreciated as am running out of time with this, thanks in advance.任何帮助将不胜感激,因为我已经没有时间了,在此先感谢。
openssl version
outputs OpenSSL 1.1.1g 21 Apr 2020
openssl version
输出OpenSSL 1.1.1g 21 Apr 2020
Also let me know when you need any more information.当您需要更多信息时,请告诉我。
According to rustwasm/wasm-bindgen, openssl
crate does not support WebAssembly根据 rustwasm/wasm-bindgen,
openssl
crate 不支持 WebAssembly
This is actually an error reported by the openssl-sys build script and that's because the openssl crate doesn't have support for WebAssembly yet (I'm not sure that OpenSSL itself even does...).
这实际上是 openssl-sys 构建脚本报告的错误,这是因为 openssl 板条箱尚不支持 WebAssembly(我不确定 OpenSSL 本身是否支持...)。
