'C:\\Program' is not recognized error

问题:

I've recently tried changing my environment variables to set paths to javac.exe (among other things). It was working fine until, all of a sudden, I started getting this error. For example, I declared a JAVA_HOME variable to be

C:\Program Files\Java\jdk1.7.0_25

After which, I add

%JAVA_HOME%\bin

to the PATH variable, but this gives me an error:

'C:\Program' is not recognized as an internal or external command, operable command or batch file.

This error makes it seem like it's running into problems with the space in "Program Files". This is weird, though, since it wasn't doing this for a good while, then started. Further, there are other variables with spaces in them that work just fine. I've tried deleting the variable and recreating it, putting quotes around JAVA_HOME (which goes to the correct path, but does not find javac.exe correctly)..

Any tips on what I might do?

This is on Windows 7.

EDIT:

The environment variables were set by going Control Panel > Advanced System Settings > Environment Variables. The value of the variables were set by copying the address of the folder I want through an Explorer window. I added it to the PATH environment variable by appending the address with a space between the preceding variable and a semicolon at the end, as such:

C:\Users\Demo_User_1\AppData\Roaming\npm; %JAVA_HOME%

where the JAVA_HOME variable is defined as such:

C:\Program Files\Java\jdk1.7.0_25

I test the value of the variable through a command prompt by typing %JAVA_HOME%, and that's where I get the resulting error of "'C:\Program' is not recognized..."

The results of 'set' are as follows:

Okay, that makes it clearer.

There are two main problems here.

First of all, the reason you're getting 'C:\Program' is not recognized... is, of course, because it contains spaces. The fact that you have it quoted in the PATH environment variable has no relation to how %JAVA_HOME% is interpreted at the prompt. You have two options.

1. Quote it when you define the variable, i.e. set JAVA_HOME to "C:\Program Files\Java\jdk1.7.0_25"
2. Quote it when you invoke it. Type "%JAVA_HOME%\bin" at the prompt. Of course, you'll get the "not recognized as an internal or external command, operable program or batch file" error unless you end the path with an executable (e.g. "%JAVA_HOME%\bin\javac.exe"), but you'll see that this way it complains about '"C:\Program Files\Java\jdk1.7.0_25"' rather than 'C:\Program'.

Second, you can't use environment variables in the path. You can use environment variables when you set the path at the command prompt. For example,

set PATH=%PATH%;%JAVA_HOME%

will work, but that's because %JAVA_HOME% is expanded at the command line and PATH is set to the result. If you check the value of PATH, you'll see that it ends with C:\Program Files\Java\jdk1.7.0_25, not %JAVA_HOME%.

Also, if javac.exe is in the bin subdirectory, you'll need to include that in the path, i.e. add ;C:\Program Files\Java\jdk1.7.0_25\bin to the path.

(BTW, you have %JAVA_HOME% in the path twice, and there's an extra semicolon after the second one.)

回答2:

Yet another solution is to do this: C:\Program Files has a short name

C:\Progra~1

in windows.

so simply write Progra~1 instead of the Program Files. {added missing 'r'}

回答3:

Is the path you are setting the JAVA_HOME environment variable in a user variable or a system variable? You cannot use user variables within system variables. So if JAVA_HOME is defined as a user variable and you are adding it to your system path that won't work.

From the output of your set command it looks like %JAVA_HOME% is not being resolved. It should show the expanded version not the one with % signs in.

Add a Path user variable and add %JAVA_HOME%\bin to that. Windows will add your user path to the end of the system path.

You should not need quotes in the JAVA_HOME variable even if it contains spaces.

回答4:

Even though Adi Inbar is pretty clear on the problem, I think his workaround isn't the best solution, because it tries to patch around the original problem: spaces in the path of your JDK installation.

The best way to solve your problem is actually reinstalling JDK to a space-less path. All other workarounds will cause you headaches in the long run.

回答5:

just add cd before adding the location eg: instead of

C:\Program Files\Java\jdk1.7.0_25

use

cd C:\Program Files\Java\jdk1.7.0_25

this helped me.

回答6:

if you are Windows 10, Use Browse Folder rather than Edit text. I had similar issue and this got resolved using above method.

Hope this helps!
