Getting System.ComponentModel.Win32Exception (2): No such file or directory

Unfortunately I'm also having the same issue.

M1 Pro Macbook Pro 14"
Monterey 12.3
Unity 2020.3.31f LTS

Hi,

I faced the same issue with the LTS versions. As I am using an M1 PRO 14" MacBook I gave a try to the latest official silicon editor - even if it is not an LTS - and it worked just fine.

OS: macOS Monterey 12.3 Unity Editor: 2021.2.16f1 Silicon

I hope t$$anonymous$$s helps.

Thank you all for the response. I tried the workaround on my project but it is not compatible or there is new error thrown when I update it in 2021.2.16f1.

If no luck or no fixes on t$$anonymous$$s issue, It is better to do it on windows pc/laptop.

For those who face the issue on the Linux. I fixed it by adding the code provided by @M_R_Antonio but with some slight changes.

First install the python2 package if it doesn't exits:

 sudo apt install python2

Then you have to find your phyton2 location:

 name@mac$$anonymous$$ne:~$ whereis python2
 python2: /usr/bin/python2

After you change environment line to:

 System.Environment.SetEnvironmentVariable("EMSDK_PYTHON", "/usr/bin/python2");

Surely your path can be different but most likely it's gonna be the same.

After that I've encountered another lib dependency issue:

 error w$$anonymous$$le loading shared libraries: libtinfo.so.5

but I was able to fix it by installing libncurses5:

 sudo apt install libncurses5

Hope that's gonna help someone.
