Win11下VS Code安装扩展时出现ERR_CONNECTION_RESET错误求助

问题现象 #

Win11强制更新后，VS Code出现以下异常：

1. 安装扩展时触发连接重置错误：

[error] net::ERR_CONNECTION_RESET: Error: net::ERR_CONNECTION_RESET
    at SimpleURLLoaderWrapper.<anonymous> (node:electron/js2c/browser_init:105:7047)
    at SimpleURLLoaderWrapper.emit (node:events:526:28)

2. 启动VS Code时的错误日志：

3. 重启路由器后尝试安装扩展，出现取消错误：

4. 关闭防火墙/杀毒软件、刷新DNS后，仍出现XHR失败错误：

2023-03-16 19:57:00.011 [error] Error: XHR failed at v.onerror (vscode-file://vscode-app/c:/Users/malve/AppData/Local/Programs/Microsoft%20VS%20Code/resources/app/out/vs/workbench/workbench.desktop.main.js:72:1399)

其他网络软件运行正常，仅VS Code受影响。

解决办法 #

1. 处理Tabnine扩展兼容性问题 #

• 卸载旧版Tabnine扩展，重新安装最新版本：Tabnine可能因VS Code版本更新后API废弃导致报错，新版通常会适配当前VS Code API。
• 若暂时不需要Tabnine，可直接禁用该扩展，排除干扰后再测试网络连接。

2. 重置VS Code网络相关设置 #

• 打开VS Code，按下Ctrl+Shift+P打开命令面板，输入Preferences: Open Settings (JSON)，添加以下配置强制禁用代理：

  "http.proxy": "",
  "http.proxyStrictSSL": false,
  "https.proxy": "",
  "https.proxyStrictSSL": false,
  "network.proxy.allowLocalNetwork": true,
  "network.proxy.allowLocalNetworkProxies": true
  

• 保存设置后重启VS Code。

3. 重置VS Code应用数据 #

• 关闭VS Code，打开文件资源管理器，导航到以下路径：
  C:\Users\<你的用户名>\AppData\Roaming\Code
• 备份extensions文件夹（避免丢失已安装扩展），然后删除Code文件夹内的所有内容。
• 重新启动VS Code，初始化后再尝试安装扩展。

4. 检查Win11更新后的网络权限 #

• 打开Windows设置 -> 隐私和安全性 -> Windows安全中心 -> 应用和浏览器控制 -> 基于信誉的保护设置。
• 确保VS Code未被列入阻止列表，同时检查“应用控制”中是否限制了VS Code的网络访问权限。
• 打开设置 -> 网络和Internet -> 代理，确认自动代理设置未被Win11更新强制启用，若开启则手动关闭。

5. 修复或重装VS Code #

• 打开Windows设置 -> 应用 -> 应用和功能，找到Visual Studio Code，选择“修改”，点击“修复”按钮尝试修复安装。
• 若修复无效，卸载VS Code并下载最新版本重新安装，安装时选择“为所有用户安装”选项。
