ESP8266 D1 Wifi board, can't find the port on MAC OS

[makehobbyrc]

Well to be honest I am not to sure what stage made it.. i installed many things several times (CH340 driver, libraries for ESP8266, Python...) so i can't tell at what point it worked.. sorry

[makehobbyrc]

Ok thanks... when you say: IN CODE TAGS.. I don't see what you mean. I copy then past the code, but WHERE?? (Is it in the Reply text window? With the "Pre-formatted text more" or something..? Thanks...

Alternatively Auto format your code in the IDE, select all of it, use Copy for forum in the IDE and paste it here so that it is in code tags to make it easier to read and copy for examination

thanks, so I am following the manual: at the stage where I entered "cd esp8266/tools" in my Terminal, it comes back with the error message: "No such file or directory"... I believe I have followed all previous steps properly. Any help? (I am a beginner I appreciate all your support!).

Is that it...? I think so...

[makehobbyrc]

Oh WAIT! i was reading the Windows section not the Mac section... I have a clue "If you get an error message stating that python3 is not found, you will need to install it (most modern UNIX-like OSes provide Python 3 as part of the default install). To install you will need to use sudo yum install python3 , sudo apt install python3 , or brew install python3 as appropriate. " I my case only the "apt" works.

Ok now I am stuck again: to "download binary tools" i need to type: cd esp8266/tools python3 get.py. But it fails. So I try to install Python 3 (with sudo apt install python3). It invited me to instal Java JDE which I did. Now i try sudo apt install python3 and this time I have Unable to locate an executable at "/Library/Java/JavaVirtualMachines/jdk-16.0.1.jdk/Contents/Home/bin/apt" (-1). I Manually went into this folder, their isn't apt indeed... More ideas..?

Installing a package esp8266 package means the following:

• Start Arduino and open the Preferences window.
• Enter https://arduino.esp8266.com/stable/package_esp8266com_index.json into the File>Preferences>Additional Boards Manager URLs field of the Arduino IDE. You can add multiple URLs, separating them with commas.
• Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).

Did you do the same?
Do you see your right board in the list of boards in Arduino IDE?

[makehobbyrc]

Yes all of these steps I think I did successfully.. I have [quote="Boffin, post:27, topic:853450"]
https://arduino.esp8266.com/stable/package_esp8266com_index.json
[/quote], I have selected Board> WeMos D1 R1. When connected to the computer the right port is selected...
NOW: I have deleted my old 1.0.6 version of Arduino. I am now using the 1.8.13! the only error message I have left is fork/exec /bin/xtensa-lx106-elf-g++: no such file or directory Error compiling for board WeMos D1 R1.
Knowing that my D1 ESP8266 board is not connected at the moment, but if I am right this doesn't mater if I am only compiling the code right...?

[Boffin]

And? Don't pull the rubber please. File -> Examples -> 01.Basics -> Blink
Push Verify button. Wait until Done compiling. What you see?
No need to connect the board at compile time.

[makehobbyrc]

"Pull the rubber...??" I just did exactly what you said. Blink and compile... and I have fork/exec /bin/xtensa-lx106-elf-g++: no such file or directory Error compiling for board WeMos D1 R1.... still (thanks again...)

[Boffin]

Unfortunately I am not familiar with macOS. Try to read the official ESP8266 link
Instructions - Other OS.
Maybe problem is in IDE installation or in the compatibility of macOS and Arduino IDE versions.

[makehobbyrc]

ok thanks I have followed these instructions. I will search for this error message on the web and see what I find... Until next time! Best

[SteveMann]

Have you tried reinstalling the IDE?

[makehobbyrc]

The IDE is the program Arduino 1.8.13 right? If so I just yesterday installed this last version, but I can try reinstalling it..! > I have done so nothing changed. Now I have tried removing and reinstalling the ESP8266 Board from the Boards Manager... It FAILS, when doing so I get error message in the Boards Manager: java.lang.NullPointerException

[SteveMann]

Is this happening on the PC or the MAC?
If it's on a MAC, then say so in the title of the thread. I know of no one running the IDE on a MAC, but maybe if you put it in the thread title, a MAC user may come out of the closet.

If it's on a PC then we can keep troubleshooting together.

[makehobbyrc]

It a MAC. Ok your right I will add it to the title thanks ! I will get their...

[makehobbyrc]

Actually at that stage the topic isn't the same anymore. If I can I will write another post concerning my new error... thanks to all!

[SteveMann]

We're not trying to give you a hard time. (OK, maybe we do make fun of Mac users a little). But as I said, I know of no one running the IDE on a Mac, but I'm sure there may be one or two here who just haven't seen the need to admit it.

Here's why a Mac may be considered the outlier. PCs outnumber Macs in the engineering world where most of us live in, by I would guess, 100 to 1. Or more.

In the long run, if you are going to make this a serious hobby including schematic capture and PCB design, you are going to wind up with a PC.

[makehobbyrc]

ok thanks, I do have PC here If i need to do a bit. I will see.. thanks!
