firebase第一步，node.js安装程序安装visualstudio2017tools时出错；弃用警告：缓冲区（）

Node.js安装程序提供自己安装其他工具，其中包括visualstudio2017工具。此安装在某个时候引发了此问题的警告：

（节点：7292）[DEP0005]弃用警告：由于安全性和可用性问题，Buffer（）已弃用。请改用Buffer.alloc（）、Buffer.allocUnsafe（）或Buffer.from（）方法。

安装在powershell中运行，并因此警告而暂停，不允许我键入任何内容。一段时间后，它给了我这样一个信息：

 specified (or the default value) was '2700' seconds. Perhaps try a
 higher `--execution-timeout`? See `choco -h` for details.

我通过VSCode命令行继续并安装了firebase工具，该工具如下所示：

npm WARN deprecated har-validator@5.1.5: this library is no longer supported

+ firebase-tools@8.6.0

问题是:

• 我可以修复第一次安装vs2017tools吗
• 当安装等待2700秒时，我能做出任何反应吗
• 所有这些会影响我的firebase体验吗
• 我确实安装了VS2019，我可以强制nodejs使用此安装吗
