M1 Mac 上的 Pod 安装错误 - Flutter 项目与本机代码如 shared_preferences

如何解决M1 Mac 上的 Pod 安装错误 - Flutter 项目与本机代码如 shared_preferences

我在 MacBook Pro M1 上（在有人说这是因为 M1 或其他原因之前，我已经用 Flutter 和 M1 编程了几个星期，但在此之后我必须重置我的 M1）。 ..我的大问题：

每次我在运行 Pod 安装时遇到错误时，我都无法使用包含本机代码（如 gpg --verify commit.asc 或 shared_preferences）的包启动我的项目。

我在 Stack Overflow 上搜索过，到目前为止没有任何帮助。如果我在没有包的情况下开始我的项目就没有问题，这是我的 Flutter 代码，非常简单：

sqlite

这是我从 Flutter 得到的错误：

import 'dart:convert';
import 'package:Flutter/material.dart';
import 'package:http/http.dart';
import 'package:shared_preferences/shared_preferences.dart';

void main() {
 runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Home(),);
  }

}


`class Home extends StatelessWidget {
  const Home({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton.icon(
          onpressed: ()async{
            final prefs = await SharedPreferences.getInstance();
            if(prefs.containsKey("test")){
              print("available");
            }else{
              await prefs.setInt("test",1);
            }
            final send = await post("xxx",body: {
              "query":"SELECT * FROM NEWS"
            });
            print(json.decode(send.body));
          },icon: Icon(Icons.person),label: Text("Hii")
        ),),);
  }
},

我编辑了我的 Podfile 并指定了一个平台，但没有任何帮助。以下是一些细节：

我安装并重新安装了很多次 Cocoa-pods 它也没有帮助

解决方法

你需要做的不是pod install：

arch -x86_64 pod install

Cocoapods 仍然不完全支持 Apple Silicon。使用 arch -x86_64 运行命令会强制终端改用 Rosetta 2。

如果这不起作用，请尝试遵循 this article。

对我来说，在我完成这些步骤之前，这些 flutter run、flutter build ios、arch -x86_64 pod install 等都不起作用：

在终端中运行 sudo gem install ffi。
然后flutter build ios --release。并且工作正常。

运行这个命令：

arch -x86_64 sudo gem install ffi

在那之后，做你的flutter build ios --no-codesign或其他什么它会正常工作。
