Visual Studio 2022中GitHub Copilot激活失败求助

问题描述 #

同一台笔记本上，GitHub Copilot在Visual Studio Code中正常运行，但在Visual Studio 2022中无法使用。已安装对应扩展，重启VS2022并加载项目后，弹出Copilot激活码连接弹窗，点击确定后输出窗口重复出现以下错误：

已尝试将“选项 > GitHub Copilot > 接受不受信任的证书授权”设置为True，但问题仍未解决。

可行解决办法 #

方法1：导入自签名证书到Windows信任存储 #

• 定位到导致问题的自签名证书（多为公司内网代理证书）
• 打开控制面板 > 网络和 Internet > Internet 选项，切换至内容标签页，点击证书
• 在受信任的根证书颁发机构标签页，点击导入，跟随向导完成证书导入
• 重启Visual Studio 2022，重新尝试激活Copilot

方法2：配置Visual Studio使用系统代理设置 #

• 打开Visual Studio 2022，进入工具 > 选项 > 环境 > 网络
• 确认使用系统代理设置已勾选
• 若使用手动代理，确保代理地址、端口配置正确，并将GitHub相关域名加入白名单
• 重启Visual Studio后重试

方法3：更新并重置GitHub Copilot扩展 #

• 打开Visual Studio 2022，进入扩展 > 管理扩展
• 找到GitHub Copilot扩展，检查并安装可用更新
• 卸载Copilot扩展，重启Visual Studio后重新安装
• 安装完成后，进入工具 > 选项 > GitHub Copilot，确认接受不受信任的证书授权设为True，再次尝试登录

方法4：临时修改环境变量绕过证书验证 #

• 右键此电脑 > 属性 > 高级系统设置 > 环境变量
• 在系统变量中添加：
  • 变量名：NODE_TLS_REJECT_UNAUTHORIZED
  • 变量值：0
• 重启Visual Studio 2022后尝试登录

注意：此方法会降低系统安全性，仅建议测试环境使用，问题解决后请删除该环境变量
