How did you install or build pythonnet?

I run commands from "GitHub installation from master branch"
https://github.com/pythonnet/pythonnet/wiki/Installation
but I had troubles with this command

setup.py bdist_wheel --xplat

I output with error

running bdist_wheel
running build
running build_ext
error: [WinError 2] The system cannot find the file specified

then I try to look at setyp.py and found that in this part

pythonnet/setup.py

Lines 311 to 321 in f8e147b

use_shell = DEVTOOLS == "Mono" or DEVTOOLS == "dotnet"
if DEVTOOLS == "MsDev15" or DEVTOOLS == "dotnet":
if DEVTOOLS == "MsDev15":
_config = "{0}Win".format(CONFIG)
elif DEVTOOLS == "dotnet":
_config = "{0}Mono".format(CONFIG)
cmd = "dotnet msbuild /t:Restore pythonnet.15.sln /p:Configuration={0} /p:Platform={1}".format(_config, ARCH)
self.debug_print("Updating packages with xplat: {0}".format(cmd))
subprocess.check_call(cmd, shell=use_shell)

here use_shell = DEVTOOLS == "Mono" or DEVTOOLS == "dotnet"
i had no .net sdk installed and no Mono, just Visual Studio
and my DEVTOOLS had value MsDev15

and wthout shell (shell=false) this command
subprocess.check_call(cmd, shell=use_shell)
got error error: [WinError 2] The system cannot find the file specified

when I installed .net sdk
have no error more
I think it should be somewehre in requirenments, or I shoud see error to with problem definition

@vanillycpp the option --xplat is for .net core build. So try without this option, since you are using .NET Framework.

installing without --xplat has no errors during installation
but when I try to import clr I got error for witch I startetd this issue

@vanillycpp what do you get from import platform; platform.machine() ?

Currently the recognized machine mappings are:

static readonly Dictionary<string, MachineType> MachineTypeMapping = new Dictionary<string, MachineType>()
        {
            { "i386", MachineType.i386 },
            { "x86_64", MachineType.x86_64 },
            { "amd64", MachineType.x86_64 },
        };

@vanillycpp ok, we need to add x86 to the Dictionary above, thanks for reporting this! Let me know if you would like to make this PR. Here are all the possible values for platform.machine():

From this overview alone, we need to add x86, i686, and x64.

I've added the names, after the PR is merged this should work fine. Odd that this didn't show up in AppVeyor...

Hellow!
I installed pythonnet from pythonnet‑2.5.2‑cp39‑cp39‑win_amd64.whl from here and so I have the same error as in head of topic.

Next code
import platform; platform.machine()
returns 'AMD64' in upper case, so I think this is same problem.
