linux - 在 Ubuntu 上的 Arduino IDE 上编译 NodeMCU 时出错

Question

我一直在尝试使用 NodeMCU 将一段代码与 Blynk 应用程序链接，我正在 Ubuntu 上的 Arduino IDE 上编译代码。以下是我的代码:

#define BLYNK_PRINT Serial


#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "myAuthToken";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "myWifi";
char pass[] = "myPassword";
BlynkTimer timer;
void setup()
{
  // Debug console
  Serial.begin(9600);
  timer.setInterval(1000L, function);
  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
  Blynk.run();
  timer.run();
}
void function()
{
  int ldrValue=analogRead(A0);
  Blynk.virtualWrite(V1, ldrValue);
}

每当我尝试编译它时，它都会向我显示错误。以下是错误信息:

Arduino: 1.8.5 (Linux), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Disabled, All SSL ciphers (most compatible), 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

您需要安装 Python，或修复(重新链接)Arduino IDE 中指向 Python 二进制文件的文件。

打开一个终端(ctrl+alt+T)，在提示符下输入python，按< kbd>输入:

~$ python

如果终端建议安装 Python，这样做可能会解决问题:

~$ sudo apt-get install python

否则，如果你看到这个:

~$ python
Python 2.7.16 (default, Apr  6 2019, 01:42:57) 
[GCC 8.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 

这意味着 Python 已安装，但您需要修复此文件中的符号链接(symbolic link):

/home/enlightened/snap/arduino-mhall119/5/.arduino15/packages/esp8266/tools/python/3.7.2-post1/python

指向已安装的 Python 二进制文件，如下所示:

~$ ln -s /usr/bin/python /home/enlightened/snap/arduino-mhall119/5/.arduino15/packages/esp8266/tools/python/3.7.2-post1/python
