Ho riscontrato anche questo problema. Il mio caso è il seguente:
Nel testo:
HKEY_CURRENT_USER\Environment
Path REG_SZ %JAVA_HOME%\bin;C:\ProgramFiles\nodejs
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
JAVA_HOME REG_SZ C:\ProgramFiles\Java\jdk
Path REG_EXPAND_SZ C:\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\

m Files (x86)\Perforce;C:\ProgramFiles\010 Editor;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\ProgramFiles\
Git\cmd;C:\Program Files (x86)\Skype\Phone\
C:\Users\ssfang> echo %^JAVA_HOME% = "%^JAVA_HOME%" = %%JAVA_HOME%% %JAVA_HOME%
%JAVA_HOME% = "%^JAVA_HOME%" = %C:\ProgramFiles\Java\jdk% C:\ProgramFiles\Java\jdk
Ho trovato che i loro tipi di valore del registro Path
sono diversi, quindi ho verificato se il percorso è valido o meno con il comando seguente:
C:\Users\ssfang> where node java
C:\ProgramFiles\nodejs\node.exe
INFO: Could not find "java".
Di conseguenza, ho resettato l'ambiente locale (utente corrente) con i seguenti comandi ( Setx ):
C:\Users\ssfang> setx PATH %^JAVA_HOME%\bin;"C:\ProgramFiles\nodejs"
SUCCESS: Specified value was saved.
C:\Users\ssfang> reg query HKEY_CURRENT_USER\Environment /v Path
HKEY_CURRENT_USER\Environment
Path REG_EXPAND_SZ %JAVA_HOME%\bin;C:\ProgramFiles\nodejs
C:\Users\ssfang> where node java
C:\ProgramFiles\nodejs\node.exe
INFO: Could not find "java".
C:\Users\ssfang>echo %PATH%
C:\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Fi

Ma, nel processo attuale, non può propagare tali modifiche ad altri processi in esecuzione.
Tuttavia, se modifichi direttamente le variabili di ambiente dell'utente nell'Editor del Registro di sistema,
tali modifiche alle variabili di ambiente non comportano cambiamenti immediati. Ad esempio, se si avvia un altro prompt dei comandi dopo aver apportato le modifiche, le variabili di ambiente rifletteranno i valori precedenti (non quelli correnti). Le modifiche non avranno effetto fino alla disconnessione e al successivo accesso.
Per effettuare queste modifiche senza disconnettersi, trasmettere un messaggio WM_SETTINGCHANGE a tutte le finestre del sistema, in modo che qualsiasi applicazione interessata (come Windows Explorer, Program Manager, Task Manager, Pannello di controllo e così via) possa eseguire un aggiornamento.
Vedere i dettagli in Come propagare le variabili di ambiente al sistema
Qui, do uno script PowerShell per farlo:
# powershell -ExecutionPolicy ByPass -File
# Standard, inline approach: (i.e. behaviour you'd get when using & in Linux)
# START /B CMD /C CALL "foo.bat" [args [...]]
# powershell -ExecutionPolicy ByPass -WindowStyle Hidden -File myScript.ps1

public static void Method(object[] first, object[] second)
{
System.Console.WriteLine("Hello world");
}
}
'@
$a = 1..4;
[string[]]$b = "a","b","c","d";
[CSharp]::Method($a, $b);

if (-not ("MyClass" -as [type])) {

p.s. there's no Remove-Type; see this answer for more on how to best work around this limitation:

I think it will be wanted when debugging.
It is much simpler to close a tab in Console and open new one in PowerShell_ISE.exe or close PowerShell.exe.
Or
Start-Job -ScriptBlock {
param([uri]$url,$OutputDir)
# download and save pages
Invoke-RestMethod $url | Out-File "$OutputDir\$($url.Segments[-1])" -Force
} -ArgumentList $link,$OutputDir
