“C:\程序”不是公认的错误。

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

我最近尝试更改环境变量以设置到javac的路径。exe(在其他事物之中)。它运行得很好，直到突然，我开始犯这个错误。例如，我声明了一个JAVA_HOME变量。

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

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

After which, I add

之后,我添加

%JAVA_HOME%\bin

% JAVA_HOME % \ bin

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

对于路径变量，但这给了我一个错误:

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

“C:\程序”不被识别为内部或外部命令、可操作的命令或批处理文件。

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)..

这个错误使得它似乎在“程序文件”中遇到了问题。但是，这很奇怪，因为它并不是在一段时间内完成的，然后就开始了。此外，还有一些其他的变量，它们的工作空间很好。我尝试过删除变量并重新创建它，在JAVA_HOME周围加上引号(这是正确的路径，但是没有找到javac)。exe正确)。

Any tips on what I might do?

有什么建议吗?

This is on Windows 7.

这是在Windows 7上。

EDIT:

编辑:

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:

环境变量的设置是通过控制面板>先进的系统设置>环境变量。变量的值是通过在Explorer窗口中复制我想要的文件夹的地址来设置的。我将其添加到PATH环境变量中，通过在前面的变量与末尾的分号之间添加一个空格，如下所示:

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

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

where the JAVA_HOME variable is defined as such:

JAVA_HOME变量的定义如下:

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

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..."

通过键入%JAVA_HOME%，我通过命令提示来测试变量的值，这是我得到“'C:\程序'的结果错误的地方……”

The results of 'set' are as follows:

5 个解决方案

Okay, that makes it clearer.

好了，这就清楚了。

There are two main problems here.

这里有两个主要问题。

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.

首先，你得到“C:\程序”的原因是不被认可的……当然，因为它包含空格。在PATH环境变量中引用的事实与如何在提示符中解释%JAVA_HOME%是没有关系的。你有两个选择。

Quote it when you define the variable, i.e. set JAVA_HOME to "C:\Program Files\Java\jdk1.7.0_25"
当您定义变量时引用它，例如将JAVA_HOME设置为“C:\程序文件\Java\jdk1.7.0_25”
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'.
当你调用它时引用它。在提示符处键入“%JAVA_HOME%\bin”。当然，您将获得“不被识别为内部或外部命令、可操作程序或批处理文件”的错误，除非您以可执行程序结束该路径(例如:“%JAVA_HOME%\bin\javac.exe”，但是您会看到这种方式会抱怨“C:\程序文件\Java\jdk1.7.0_25”，而不是“C:\程序”。

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,

其次，您不能在路径中使用环境变量。当您在命令提示符中设置路径时，您可以使用环境变量。例如,

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%.

将会工作，但这是因为%JAVA_HOME%在命令行中被扩展，并且路径被设置为结果。如果您检查PATH的值，您将看到它以c:programjava\ jdk1.7.0_25结尾，而不是%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.

同样,如果javac。exe在bin子目录中，您需要将其包括在path中，即add;C:\程序文件\Java\jdk1.7.0_25\bin到路径。

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

(顺便说一下，在路径中有%JAVA_HOME%，在第2条后面有一个额外的分号。)

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

另一个解决方案是这样做:C:\Program Files短名称

C:\Progra~1

C:\ Progra ~ 1

in windows.

在windows。

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

所以简单的写程序~1而不是程序文件。{添加失踪' r ' }

#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.

在用户变量或系统变量中设置JAVA_HOME环境变量的路径是?不能在系统变量中使用用户变量。因此，如果JAVA_HOME被定义为一个用户变量，并且您将它添加到您的系统路径中，这将不起作用。

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.

从您的set命令的输出中，看起来%JAVA_HOME%没有得到解决。它应该显示扩展后的版本，而不是有%符号的版本。

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.

添加路径用户变量，并添加%JAVA_HOME%\bin。Windows将会将您的用户路径添加到系统路径的末端。

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

即使在JAVA_HOME变量中包含空格，也不应该需要引号。

#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.

尽管Adi Inbar对这个问题非常清楚，但我认为他的解决方案并不是最好的解决方案，因为它试图解决最初的问题:JDK安装路径中的空间。

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.

解决您的问题的最好方法实际上是将JDK重新安装到无空间的路径上。从长远来看，所有其他的变通方法都会让你头疼。

#5

just add cd before adding the location eg: instead of

在添加位置之前添加cd:而不是。

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

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

use

使用

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

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

this helped me.

这帮助了我。
