Tauri v2集成photon_rs时wasm-bindgen依赖冲突求助

我正在使用 Tauri v2 开发应用，尝试集成图像处理库 photon_rs。运行 cargo run 时触发 wasm-bindgen 版本冲突错误：

Updating crates.io index

我并未计划在 Tauri 或 photon_rs 中使用 WASM。已知 photon_rs 支持通过特性标志排除 WASM 依赖，但在 Cargo.toml 中配置 photon-rs = { version = "0.3.2", default-features = false } 后无效果。推测是 Tauri 间接引入的 wasm-bindgen 导致依赖树中版本冲突。运行 cargo update --package wasm-bindgen 仍报错：

我的 Cargo.toml 配置如下：

[package]
name = "blurryface"
version = "0.0.0"
description = "A Tauri App"
authors = ["you"]
edition = "2021"

[build-dependencies]
tauri-build = { version = "2", features = [] }

# [patch.crates-io]
# wasm-bind = { git = 'https://github.com/serde-rs/serde.git' }

[dependencies]
tauri = { version = "2", features = [], default-features = false }
serde = { version = "1", features = ["derive"] }
serde_json = "1"
grep = "0.3.1"
walkdir = "2.5.0"
termcolor = "1.4.1"
ignore = "0.4.22"
tauri-plugin-dialog = "2"
tauri-plugin-shell = "2"
photon-rs = { version = "0.3.2", default-features = false } # disables wasm
# enable_wasm

问题 #

1. 能否从 Tauri 侧禁用 WASM 依赖？
2. 还有哪些强制指定版本的方法？
3. 是否应该 fork photon_rs 手动移除不需要的依赖？
4. 还有其他可行的解决方案吗？

1. 从 Tauri 侧禁用 WASM 依赖 #

可以通过精简特性集来减少 WASM 相关依赖的引入：

• 对 tauri-plugin-shell 也设置 default-features = false，仅启用你实际需要的特性，避免它间接引入 softbuffer 带来的 wasm-bindgen；
• 强制指定 softbuffer 的特性，关闭其 WASM 支持：

  [dependencies]
  softbuffer = { version = "0.4.0", default-features = false, features = ["x11"] } # 或根据系统选"wayland"
  

• 检查 Tauri 的特性列表，确认是否有额外的网络或 runtime 特性默认启用了 reqwest，进一步调整 tauri 的特性参数。

2. 强制指定版本的方法 #

• 使用 [patch.crates-io]：强制将 wasm-bindgen 升级到兼容版本，注意需验证 photon-rs v0.3.2 是否能适配该版本：

  [patch.crates-io]
  wasm-bindgen = { version = "0.2.95" }
  

• 使用 cargo override：在本地项目中强制锁定版本，执行命令：

  cargo override set wasm-bindgen@0.2.95
  

  若 photon-rs 出现编译错误，说明版本不兼容，此方法无效。

3. 是否应该 fork photon_rs 手动移除依赖 #

这是可行方案，但维护成本较高：

• 如果 photon-rs v0.3.2 中的 wasm-bindgen 仅服务于 WASM 功能，你可以 fork 仓库后，将 wasm-bindgen 移至特性依赖，或直接删除相关代码；
• 但后续需要自行维护 fork 版本，接收上游更新，仅在其他方案均无效时建议采用。

4. 其他可行解决方案 #

• 升级 photon_rs：检查 photon_rs 新版本（如 0.4+），新版本可能已升级 wasm-bindgen 依赖版本，与 Tauri 兼容；
• 替换图像处理库：改用 image 库，它是 Rust 生态中成熟的图像处理库，无不必要的 WASM 依赖，能满足大部分图像处理需求；
• 排查依赖树：运行 cargo tree -p wasm-bindgen 查看完整依赖路径，定位强制引入特定版本的 crate，针对性调整其特性或版本。
