系統找不到在Powershell中找不到路徑/命令錯誤

Question

我有一個Elasticsearch的安裝，它可以正常工作好幾個月，但根據Powershell已經莫名其妙地失蹤了。我能想到的唯一事情最近已經改變了，那就是我更新了Java。

當我嘗試使用完整路徑，我得到了以下錯誤來運行它：

PS C:\> C:\elasticsearch\bin\elasticsearch.bat 
The system cannot find the path specified. 

的路徑存在和不存在拼寫錯誤，你可以在這裏看到：

PS C:\elasticsearch\bin> dir 

    Directory: C:\elasticsearch\bin 

Mode    LastWriteTime   Length Name

-a----   8/7/2016 10:13 PM   6501 service.bat 

當我嘗試從目錄本身運行它，我得到以下消息：

PS C:\elasticsearch\bin> elasticsearch.bat 
elasticsearch.bat : The term 'elasticsearch.bat' is not recognized as the name of a cmdlet, function, script file, or 
operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try 
again. 
At line:1 char:1 
+ elasticsearch.bat 
+ ~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : ObjectNotFound: (elasticsearch.bat:String) [], CommandNotFoundException 
    + FullyQualifiedErrorId : CommandNotFoundException 

Suggestion [3,General]: The command elasticsearch.bat was not found, but does exist in the current location. Windows Pow 
erShell does not load commands from the current location by default. If you trust this command, instead type: ".\elastic 
search.bat". See "get-help about_Command_Precedence" for more details. 

我不'噸有處理PowerShell的錯誤，一個強大的知識，所以我只試了幾件事情：

1. 重新安裝Elasticsearch
2. 添加含有elasticsearch.bat的路徑
3. 運行elasticsearch.bat使用命令的目錄./elasticsearch.bat

這些都不會改變任何東西。

這裏的elasticsearch.bat的內容：

@echo off 

SETLOCAL enabledelayedexpansion 
TITLE Elasticsearch 2.3.5 

SET params='%*' 

:loop 
FOR /F "usebackq tokens=1* delims= " %%A IN (!params!) DO (
    SET current=%%A 
    SET params='%%B' 
    SET silent=N 

    IF "!current!" == "-s" (
     SET silent=Y 
    ) 
    IF "!current!" == "--silent" (
     SET silent=Y 
    ) 

    IF "!silent!" == "Y" (
     SET nopauseonerror=Y 
    ) ELSE (
     IF "x!newparams!" NEQ "x" (
      SET newparams=!newparams! !current! 
     ) ELSE (
      SET newparams=!current! 
     ) 
    ) 

    IF "x!params!" NEQ "x" (
     GOTO loop 
    ) 
) 

SET HOSTNAME=%COMPUTERNAME% 

CALL "%~dp0elasticsearch.in.bat" 
IF ERRORLEVEL 1 (
    IF NOT DEFINED nopauseonerror (
     PAUSE 
    ) 
    EXIT /B %ERRORLEVEL% 
) 

"%JAVA_HOME%\bin\java" %JAVA_OPTS% %ES_JAVA_OPTS% %ES_PARAMS% -cp "%ES_CLASSPATH%" "org.elasticsearch.bootstrap.Elasticsearch" start !newparams! 

ENDLOCAL

PS C:\> C:\elasticsearch\bin\elasticsearch.bat 
The system cannot find the path specified. 

你確定這不是批處理文件的輸出？換句話說，批處理文件中的某些內容找不到指定的路徑（可能是java.exe）。如果PowerShell找不到該文件，則會收到類似於第二次嘗試的錯誤消息。

說出你的第二次嘗試：

PS C:\elasticsearch\bin> elasticsearch.bat 

隨着錯誤消息的狀態，這不會對文件在當前文件夾的工作。您需要明確指定當前文件夾：

PS C:\elasticsearch\bin> .\elasticsearch.bat
