Python找不到某些windows可执行文件

我似乎无法在windows上用python运行某些特定的可执行文件。 在运行这些可执行文件时，我得到一个“未找到文件”错误

我可以使用多种方法运行其他可执行文件，如winver.exe：

subprocess.Popen( [r"C:\Windows\System32\winver.exe"] )
subprocess.run( [r"C:\Windows\System32\winver.exe"] )
subprocess.run( ["winver"] )
subprocess.Popen( ["winver"] )
os.system( "winver" )

但我似乎无法让wsl、bash、ssh或sftp正常工作：

subprocess.Popen( [r"C:\Windows\System32\wsl.exe"] )
subprocess.run( [r"C:\Windows\System32\wsl.exe"] )
subprocess.run( ["wsl"] )
subprocess.Popen( ["wsl"] )
os.system( "wsl" )

subprocess.Popen( [r"C:\Windows\System32\bash.exe"] )
subprocess.run( [r"C:\Windows\System32\bash.exe"] )
subprocess.run( ["bash"] )
subprocess.Popen( ["bash"] )
os.system( "bash" )

subprocess.Popen( [r"C:\Windows\System32\OpenSSH\ssh.exe"] )
subprocess.run( [r"C:\Windows\System32\OpenSSH\ssh.exe"] )
subprocess.run( ["ssh"] )
subprocess.Popen( ["ssh"] )
os.system( "ssh" )

subprocess.Popen( [r"C:\Windows\System32\OpenSSH\sftp.exe"] )
subprocess.run( [r"C:\Windows\System32\OpenSSH\sftp.exe"] )
subprocess.run( ["sftp"] )
subprocess.Popen( ["sftp"] )
os.system( "sftp" )

sftp的错误：

如果我在OpenSSH目录上尝试相同的方法，则不会完全找到它

os.chdir( "C:\Windows\System32\OpenSSH" )
val = os.system( "dir" )

print( val )

正如您所期望的，所有这些在python之外都可以很好地工作，而且它们也可以从.bat开始工作

你能把stacktrace贴出来吗？注意，chdir的参数也忽略了原始前缀。请发布同样有效的.bat文件。.bat文件只包含一行程序名（ssh/sftp/winver）。您可以发布stacktrace吗？注意，chdir的参数也忽略了原始前缀。请发布同样有效的.bat文件。.bat文件只包含一行程序名（ssh/sftp/winver）
