Arduino IDE为什么无法连接模块？

我的 IDE 无法连接模块。我在这些事情上是新手，还在学习，我以前一直在使用一些 Arduino 电子产品，但从来没有遇到过这样的问题。我认为一切都设置正确：
但是，当我尝试编译代码时，我首先收到警告，然后在上传时出现以下错误：
代码：全选Arduino: 1.8.10 (Windows 10), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), dtr (aka nodemcu), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 2, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Executable segment sizes:


IROM   : 235644          - code in flash         (default or ICACHE_FLASH_ATTR)


IRAM   : 26908   / 32768 - code in IRAM          (ICACHE_RAM_ATTR, ISRs...)


DATA   : 1264  )         - initialized variables (global, static) in RAM/HEAP


RODATA : 752   ) / 81920 - constants             (global, static) in RAM/HEAP


BSS    : 24976 )         - zeroed variables      (global, static) in RAM/HEAP


Sketch uses 264568 bytes (27%) of program storage space. Maximum is 958448 bytes.
Global variables use 26992 bytes (32%) of dynamic memory, leaving 54928 bytes for local variables. Maximum is 81920 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

你们能否建议我对以下问题有哪些选择，或者告诉我在哪里可以找到解决方案？
