VSCode修改project-scratch-def.json报错：无法加载Schema文件

保存修改后的project-scratch-def.json文件以创建Scratch Org时，VSCode弹出以下错误：

Unable to load schema from '/Users/myname/.vscode/extensions/salesforce.salesforcedx-vscode-core-61.12.0/node_modules/@salesforce/schemas/project-scratch-def.schema.json': ENOENT: no such file or directory, open '/Users/myname/.vscode/extensions/salesforce.salesforcedx-vscode-core-61.12.0/node_modules/@salesforce/schemas/project-scratch-def.schema.json'.

我的project-scratch-def.json内容如下：

{
  "orgName": "myname company",
  "edition": "Developer",
  "features": ["EnableSetPasswordInApi"],
  "settings": {
    "lightningExperienceSettings": {
      "enableS1DesktopEnabled": true,
      "enableLightningPreviewPref": true
    },
    "mobileSettings": {
      "enableS1EncryptedStoragePref2": false
    }
  }
}

已尝试以下操作但问题仍未解决：

• 重新安装Node.js
• 重新安装Salesforce VSCode扩展包
• 重新安装Salesforce CLI
• 重启电脑
• 重载VSCode窗口
• 重建Salesforce项目
• 删除现有Scratch Org

检查扩展目录/Users/myname/.vscode/extensions/salesforce.salesforcedx-vscode-core-61.12.0/node_modules时，发现其中不存在@salesforce目录。
