mach-o 文件，但在 Flutter 中是不兼容的架构（有“arm64”，需要“x86_64”）

Question

执行dart run ffigen出现如下错误：

\n

Unhandled exception:\nInvalid argument(s): Failed to load dynamic library '/Users/bruce/homebrew/opt/llvm/lib/libclang.dylib': dlopen(/Users/bruce/homebrew/opt/llvm/lib/libclang.dylib, 0x0001): tried: '/Users/bruce/homebrew/opt/llvm/lib/libclang.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64')), '/Users/bruce/homebrew/Cellar/llvm/13.0.1_1/lib/libclang.dylib' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))\n#0      _open (dart:ffi-patch/ffi_dynamic_library_patch.dart:12:43)\n#1      new DynamicLibrary.open (dart:ffi-patch/ffi_dynamic_library_patch.dart:23:12)\n#2      initializeGlobals (package:ffigen/src/header_parser/data.dart:41:33)\n#3      initParser (package:ffigen/src/header_parser/parser.dart:48:3)\n#4      parse (package:ffigen/src/header_parser/parser.dart:22:3)\n#5      main (package:ffigen/src/executables/ffigen.dart:54:19)\n#6      _delayEntrypointInvocation.<anonymous closure> (dart:isolate-patch/isolate_patch.dart:295:32)\n#7      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:192:12)\n

我检查了我的 Flutter 环境：

\n

\xe2\x9d\xaf file /Users/bruce/dev_tools/flutter/bin/cache/dart-sdk/bin/dart\n/Users/bruce/dev_tools/flutter/bin/cache/dart-sdk/bin/dart: Mach-O 64-bit executable x86_64\n

\n

当我运行brew install llvm安装 llvm 时，我得到的是 arm64 的库，我认为这是导致错误的原因：

\n

\xe2\x9d\xaf lipo -info /Users/bruce/homebrew/Cellar/llvm/13.0.1_1/lib/libclang.dylib\nNon-fat file: /Users/bruce/homebrew/Cellar/llvm/13.0.1_1/lib/libclang.dylib is architecture: arm64\n

Flutter SDK好像没有针对Apple Silicon的版本，那么如何解决这个问题呢？

我尝试安装Arm平台的Dart SDK，但仍然不起作用，使用独立的Dart环境，出现以下错误：

Answer 1

在M1 mac上运行，这两个命令解决了我的问题。

$ arch -arm64 brew install llvm

$ sudo gem install ffi

Answer 2

这是对我有用的步骤，

1. 使用自制程序 x86_64 版本安装 llvm arch -x86_64 /usr/local/homebrew/bin/brew install llvm

2. 安装 x86-64 版本的 ffi sudo arch -x86_64 gem install ffi

3. 删除pods目录和目录Podfile中iOS

4. 使缓存无效并重新启动android studio

Answer 3

我曾经想过这个，这太糟糕了！这里的问题是你如何安装 LLVM，LLVM 本身默认通过 Home-brew 安装为 ARM64，但你应该安装它的 X86_64 版本。要解决请尝试以下操作：

1. 卸载当前的 LLVM：brew uninstall llvmss
2. 确保安装了 x86_64 的自制软件，如本文中所示
3. 然后使用 homebrew x86 版本安装：arch -x86_64 /usr/local/homebrew/bin/brew install llvm

然后你 ffi gen 就可以工作了。

Answer 4

此错误出现在配备 Apple Silicon M1 芯片的 MacBook 上。仅当通过配置为使用 Rosetta 打开的终端运行命令时，才会出现此问题。

我所做的解决方法是：

1. 克隆终端应用程序
2. 将其重命名为“终端 x86_64”
3. 通过右键单击+“获取信息”获取信息
4. 取消选中“用 Rosetta 打开”

因此，每次我想运行导致此错误的命令时，我都会使用“Terminal x86_64”来运行它，你猜怎么着？有用。
