hello everyone I am new to Arduino , I am using an older IMac (21.5 " mid2011)
I bought it use from someone and it was wipe clean
I am tryin to learn about Arduino and I look up some videos on youtube
I downloaded the Arduino IDE and install the FTDI usb driver and added thehttp://arduino.esp8266.com/stable/package_esp8266com_index.json
I bought the esp8266 node mcu 1.0 12E module
I have two problems I can seem to solve one is my board shows as
also
when I try to upload I get this message
Arduino: 1.8.12 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

This report would have more information with
please help thanks a lot
I can't help with Mac problems, sorry.
It does not matter how your board shows as long as it shows when you connect it and disappears when you connect it.
I suggest that you remove your email address unless you want to receive spam.

The problem is the ESP8266 platform has a tool dependency on Python 3, but rather than installing a dedicated copy of Python 3 with the package, the ESP8266 platform developers assume you have Python 3 already installed at /usr/local/bin/python3. /Users/ramdass/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3 is just a symlink to that location. So either you have Python 3 installed somewhere else, like /usr/bin/python3, or maybe you don't have Python 3 installed at all. If the former, you need to modify the symlink, as described here . If the latter, you need to install Python (and possibly modify the symlink as well if it was installed to a location other than /usr/local/bin/python3.

### Problem Description
Edit by @devyte:
The problem seems to be that the build process doesn't find python3 on MacOS. Duplicate WiFi libs warning is unrelated.
Original Problem Description follows.
--------------------------------------------------------------------------------------------------------------------
When including the library and selecting the board, any code i use whether it is the wifi search or the code I was looking to use in my project, I get the following error:
```
Arduino: 1.8.10 (Mac OS X), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"
Multiple libraries were found for "ESP8266WiFi.h"
Used: /Users/xxxx/Library/Arduino15/packages/esp8266/hardware/esp8266/2.6.3/libraries/ESP8266WiFi
fork/exec /Users/xxxx/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory
Error compiling for board NodeMCU 1.0 (ESP-12E Module).
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
```
If i remove the library it finds nothing. This is a new installation on my mac so there wouldn't be any conflicts. Not sure if anyone has experienced the same..? Seems likely unless i'm doing something very wrong, but looking at the current issue list I cannot see anything like this.
Thanks
### [MCVE](https://stackoverflow.com/help/mcve) Sketch
```cpp
/*
This sketch demonstrates how to scan WiFi networks.
The API is almost the same as with the WiFi Shield library,
the most obvious difference bei›‹‹›ng the different file you need to include:
*/
#include "ESP8266WiFi.h"
void setup() {
Serial.begin(115200);
// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);
Serial.println("Setup done");
}
void loop() {
Serial.println("scan start");
// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println("scan done");
if (n == 0) {
Serial.println("no networks found");
} else {
Serial.print(n);
Serial.println(" networks found");
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(": ");
Serial.print(WiFi.SSID(i));
Serial.print(" (");
Serial.print(WiFi.RSSI(i));
Serial.print(")");
Serial.println((WiFi.encryptionType(i) == ENC_TYPE_NONE) ? " " : "*");
delay(10);
}
}
Serial.println("");
// Wait a bit before scanning again
delay(5000);
}
