ERROR:'keytool' is not recognized as an internal or external command, operable program or batch file

问题

When i use the command

C:\>keytool -list -alias androiddebugkey 
            -keystore .android\debug.keystore 
            -storepass android -keypass android

I get this error:

'keytool' is not recognized as an internal or external command, operable program or batch file.

I'm not able to get the certificate fingerprint(MD5) on my computer.

i have ensured that the keystore file is present in the appropriate location.

Any help?

回答1:

Check that the directory the keytool executable is in is on your path. (For example, on my Windows 7 machine, it's in C:\Program Files (x86)\Java\jre6\bin.)

回答2:

This worked for me !! :

Go to this path or where ever you have your keytool.exe file

C:\Program Files\Java\jre7\bin

Hold shift and right click -> then press Open command window here

terminal will pop up, paste this in:

keytool -list -v -keystore "C:\Users\"Your-User-Name(no quotes)"\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

gives you both MD5 and SHA1

回答3:

Found it.

GO TO:

my computer->rightClick->properties->Advanced system settings->environment variables->find path in system variables->dbl click-> paste the "C:\Program Files\Java\jdk1.6.0_16\bin"->OK

GO TO:

cmd -> keytool -list -alias androiddebugkey -keystore "C:\Users\meee\.android\debug.keystore" -storepass android -keypass android

回答4:

On windows 8, go to C:\Program Files\Java\jre7\bin and in the address bar, type "cmd" without the quotes. This will launch the terminal. Then type in string as describe here.

回答5:

So if you have the following structure now:

 C:\Program Files\Java\jre6\bin\
                                keytool.exe
                                debug.keystore

then execute:

C:\Program Files\Java\jre6\bin>keytool -list -alias androiddebugkey -keystore debug.keystore -storepass android -keypass android

回答6:

all you can do is to navigate to your jre destination in your computer via command line and then once you reach bin, you type the keytool command and it would work.

C:\Program Files (x86)\Java\jre7\bin>
C:\Program Files (x86)\Java\jre7\bin>keytool -list -v -keystore"%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

Make sure JAVA_HOME is set and the path in environment variables reflects the bin directory of JAVA_HOME. Basically, the PATH should be able to find the keytools.exe file in your jdk location.

回答8:

Go to My computer -> right click -> system properties -> environmental variables -> Path -> add you jdk/bin to this path
```
C:\Program Files\Java\jdk1.8.0_211\bin
```

*if this not work then

In cmd set the path by using the below command

set PATH=C:\Program Files\Java\jdk1.8.0_211\bin

now the path is set now you can use the keytool

回答9:

if you want to run keytool from any location of terminal

example: C:>keytool

you need to add the system variables

for Windows:

1) create:
JAVA_HOME
C:\Program Files\Java\jdk1.7.0_45

2) add to Path
%JAVA_HOME%\bin;

回答10:

Easy, just find the location where keytool executable is, normally is in java/jre(Version)/bin forexample in my computer is in C:\Program Files\Java\jre7\bin. all you have to do is go to environment variables, click PATH to make it active, then click edit, then add complete path where your keytool is, for me i will add C:\Program Files\Java\jre7\bin this will allow you to execute keytool commands without going to the directory where keytool is installed.

回答11:

This means, that your shell couldn't find the tool on your harddisk.

Change the working directory to C:\Program Files\Java\jre6\bin\
Execute keytool -list -alias androiddebugkey keystore <full directory name make sure that you use enclosing in quotes> -storepass android -keypass android

Add C:\Program Files\Java\jre6\bin\ to your PATH variable

回答12:

Give:

keytool -list -keystore ~/.android/debug.keystore

Also in your line there is a space in keystore. Please check it.

回答13:

Open "Environment Variables" (you can get to it from your start menu search in Win10) double check the path that the jdk is in, to make sure it exists. For me, it said "...jdk1.8/bin" But when I copied that into Windows Explorer or command prompt, it said that it didn't exist. I checked where it should have been, and it said "jdk1.8.0_77"

A simple rename of the setting in Android Studio and keytool was working!

回答14:

In my case problem was in using PowerShell instead of CMD :)

回答15:

I suffered alot trying to find a solution to it and finally I found the solution by first setting the jre path to system variables by navigating to::

control panel > System and Security > System > Advanced system settings

Under System variables click on new

Variable name: KEY_PATH
Variable value: C:\Program Files (x86)\Java\jre1.8.0_171\bin

Where Variable value should be the path to your JDK's bin folder.

Then open command prompt and Change directory to the same JDK's bin folder like this

C:\Program Files (x86)\Java\jre1.8.0_171\bin

then copy and paste the code below in cmd

keytool -list -v -keystore "C:\Users\user\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

回答16:

The Works for fine

Go to Path

C:\Program Files\Java\jre7\bin> keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Developer\.android\debug.keystore"

Then enter Ketsore Password and job done!!

回答17:

Open Command prompt type this..

"c:\Program Files(x86)\Java\jdk1.7.0\bin\keytool.exe" -list -v -alias androiddebugkey -keystore "C:\Users\EIS.android\debug.keystore" -storepass android -keypass android

Then Hit Enter MD5 and SHA1 key will get

回答18:

I know there are already several answers but none of them worked for me, so i am posting one that worked for me, may be helpful for someone.

First of all directory to keytool.exe must be on path

and if instead of directory being on path it is giving error then Try starting command line as a normal user instead of as a administrator or changing the directory to home directory

回答19:

For windows 10 you need to path C:\Program Files\Java\jre1.8.0_161\bin

restart command and open

回答20:

Locate where your keytool.exe inside java installation folder

mine is C:\Program Files\Java\jre1.8.0_181\bin open cmd anywhere and run

SET PATH=%PATH%;C:\Program Files\Java\jre1.8.0_181\bin;

change the path to the path you located your keytool.exe
