Hi. Sorry, I don’t speak English well, I need help installing mediasoup on Win 10.
I do absolutely everything and it seems that I have already won many problems, but with the latter I can not do anything at all…
During the installation process, I get this error:
```auto
Build type: native build
Project name: mediasoup-worker
Project version: undefined
meson.build:1:0: ERROR: Unknown compiler(s): [['icl'], ['cl'], ['cc'], ['gcc'], ['clang'], ['clang-cl'], ['pgcc']]
The following exception(s) were encountered:
Running "icl " gave "[WinError 2] The specified file cannot be found"
Running "cl /?" gave "[WinError 2] The specified file cannot be found"
Running "cc --version" gave "[WinError 2] The specified file cannot be found"
Running "gcc --version" gave "[WinError 2] The specified file cannot be found"
Running "clang --version" gave "[WinError 2] The specified file cannot be found"
Running "clang-cl /?" gave "[WinError 2] The specified file cannot be found"
Running "pgcc --version" gave "[WinError 2] The specified file cannot be found"
```
The certificate is installed, I ran this file too
```auto
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"
```
I reread all the topics and did not find a solution to my problem … I am desperate
Thank you in advance

God … what a dumb one I am. i ran the command in terminal vs code…
Everything works
