在配置Flutter环境遇到：× Windows Version (Unable to confirm if installed Windows version is 10 or greater)

一、问题描述

在配置flutter环境的过程中，出现了以下问题：

Windows Version (Unable to confirm if installed Windows version is 10 or greater)

二、解决问题

我已经能够重现该问题。事实上，正如@liscanso首先发现的那样，它与系统语言有关，因为没有参数的命令输出是依赖于语言的。所以我提出了一个可以帮助绕过这个问题的修复程序。systeminfo

1、把该目录下的文件替换为下面的代码（它与原点相同，但进行了一些调整）：（FLUTTER-SDK-DIR）\packages\flutter_tools\lib\src\windows\windows_version_validator.dart

// Copyright 2014 The Flutter Authors. All rights reserved.
// Use of this source code is governed by a BSD-style license that can be

import 'package:process/process.dart';

import '../base/io.dart';
import '../doctor_validator.dart';

// FIX #1 - Remove everything from line 10 to 20 in original source code.

/// Validator for supported Windows host machine operating system version.
class WindowsVersionValidator extends DoctorValidator {
  const WindowsVersionValidator({required ProcessManager processManager})
      : _processManager = processManager,
        super('Windows Version');

  final ProcessManager _processManager;

  @override
  Future validate() async {

// FIX #2 - Replace 'systeminfo' by 'ver' command
    final ProcessResult result =
        await _processManager.run(['ver'], runInShell: true);

    if (result.exitCode != 0) {
      return const ValidationResult(
        ValidationType.missing,
        [],
        statusInfo: 'Exit status from running `systeminfo` was unsuccessful',
      );
    }

    final String resultStdout = result.stdout as String;

// FIX #3 - Remove brackets from output
    final String resultAdjusted = resultStdout.replaceAll('[','').replaceAll(']','');

// FIX #4 - Split the output at spaces, and get Windows version at position 3.
//          Split again at dots and get the major version at position 0.
//          Cast the output to int.
    final int winver = int.parse(resultAdjusted.split(' ').elementAt(3).split('.').elementAt(0));

    // Use the string split method to extract the major version
    // and check against the [kUnsupportedVersions] list
    final ValidationType windowsVersionStatus;
    final String statusInfo;

// FIX #5 - Check if Windows major version is greater than 10.
//          Succeeds if true.
    if (winver >= 10) {
      windowsVersionStatus = ValidationType.installed;
      statusInfo = 'Installed version of Windows is version 10 or higher';
    } else {
      windowsVersionStatus = ValidationType.missing;
      statusInfo =
          'Unable to confirm if installed Windows version is 10 or greater';
    }

    return ValidationResult(
      windowsVersionStatus,
      const [],
      statusInfo: statusInfo,
    );
  }
}

2、删除文件。（FLUTTER-SDK-DIR）\bin\cache\flutter_tools.stamp/
3、再跑一次。flutter doctor
OK，问题解决！

三、解决问题的原理

基本上，我改变了 Flutter 检查 Windows 版本的方式，通过分析快速、更高效的输出，而不是检查长期命令中依赖于语言的输出。这是在空格字符处拆分输出，获取第四个值（位置 3），在点处再次拆分，将第一个值（位置 0）转换为 int 并检查它是否大于或等于 10 的问题。无需正则表达式。versysteminfo

也许这里的一些贡献者可以测试我的解决方案并合并代码，因此不再需要手动解决方法。
