库错误：“仅发现使用过的库”的NodeMCU1.0 ESP-12E模块错误发现“的多个库”

Question

这里是代码和错误消息，在我使用代码之前，该代码只是一个测试文件，当我仅导入Keypad.h和Keypad_I2C.h时，它工作正常，当我仅导入ESP8266WiFi时也可以工作。H。当我尝试仅导入键盘库和ESP8266WiFi.h之一时，发生了错误。

代码：

#include <Keypad_I2C.h>
#include <Keypad.h>
//#include <ArduinoJson.h>
//#include<SoftwareSerial.h>
#include<ESP8266WiFi.h>
void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

错误消息：

自2017年以来，这是一个已知功能 sarcasm>。将键盘库作为标准库的最后一个：

//#include <ArduinoJson.h>
//#include<SoftwareSerial.h>
#include<ESP8266WiFi.h>

#include <Keypad_I2C.h>
#include <Keypad.h>

编译得很好。并为您节省更多的麻烦。将ArduinoIDE更新为1.8.12-您的版本具有一些功能，例如缺少串行监视器中的波特选择，而并不是真正有效的工具链aso。
