Arduino does not compile any at all

Hello
Arduino does not compiles any at all…

troubleshooting attempts :
choose proper boards ( tired several :Wemos d1 r2 Arduino MKR !000, Adafruit huzza )
made sure the correct port appears

changed USB cables
swapped USB ports

restarted Arduino

show verbose during completion √
Uninstalled Arduino
Reinstalled Arduino ide

same error message /error compiling "whateverboard/
wht else shoud i try?

Thanks



Do you see that button 'copy error messages' in your screenshot? Click it and it copies the errors to the clipboard.

Next you can paste them here in a post.

That does not look complete; if too big, paste it in a text file, save and attach.

Why did you try different boards? Do you have Wemos D1, MKR1000 and Huzzah?

As this relates to boards that I'm not familiar with, I doubt I can help further.

it is a large file adding an attachment as you said
thought impaired board could be the cause of the trouble have some other boards so tried in order to make sure its not board or hardware issue
Thanks

Error compiling for board WeMos D1 R1.

I have no idea what to do with that except for checking where your python3 is.

Let this go around the world and maybe somebody else has an idea how to solve it.

I found the following couple of references to this issue which might be helpful:

https://github.com/esp8266/Arduino/issues/6931

I have python installed last time when installed it helped how ever, reinstalled today to newest version didn't help i willuninstall the arduino and blow away arduino library and start restart the process
Thank

troubleshooting attempts :
choose proper boards ( tired several :Wemos d1 r2 Arduino MKR !000, Adafruit huzza )
made sure the correct port exist

changed USB cables
swapped USB ports

as somebody suggested reinstalled python 3.8 error message attachment
restarted Arduino
show verbose during completion √
Uninstalled Arduino and blew away arduino library
deleted and reinstalled ch341SER drivers
reinstalled Arduino ide
tried different esp8266 libraries

After all adjustments i am able to compile arduino boards only ( i have mega and Nano) but have to use esp8266 , and same error message appears "error compiling "esp8266/ board

what else shoud i try?

Thank you!

Read How to use this forum, and post your sketch- all of it- using code tags. And also use code tags to post your error message.

Most people here won't download files attached to a question from a new forum member.

Looks like you have installed some invalid libraries....

Error compiling for board WeMos D1 R1.

What have you put in those folders?
Backtrack... Delete your libraries. Restart with LED blinky.

it won't compile the blink example deleted the entire libraries file still get error message can't use code tags because it exceeds the number of characters

@Arrow008, do not cross-post. Threads merged.

so after deleting literally everything related to arduino including the program itself ~ reinstalled arduino got literally zero libraries except the built in default examples. tired to restart with blink yet got the (part of) error
/Users/katsiv/Library/Arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/2.5.0-4- b40a506/bin/xtensa-lx106-elf-g++ -D__ets__ -DICACHE_FLASH -U__STRICT_ANSI__
deleted it and when back to arduino all boards disappeared expect the arduinos
tired to blink - success - was happy for few seconds so back to
menage libraries type esp8266 downloaded, the boards (esp8266 appeared) tried to compile blink again - error again - honestly frustrating... yet still get error even when trying to restart with blink
what can it be ?????

As far as I know, serial Devices cant have weird Characters like space in their namens.please rename your Board and retry.
