我几乎已经完成了从 Windows 桌面构建 chromium，但我被困在最后一步，运行 gn gen out/Default。我已检查我的 Visual Studio 安装程序，Windows 10 SDK 版本 10.0.19041.0 已安装。我不知道该怎么办。整个输出如下：

C:\chromium\src>gn gen out/Default

例如，

class Test{
private:
   int* foo;
public:
   Test(int* foo){this->foo = foo;}
}

在这种情况下，有什么办法可以在析构函数中删除 foo 吗？我是否必须在析构函数中删除 foo 或者至少将其设置为 nullptr？
