javac cannot be found - CLASSPATH/Path/JAVA_HOME set for JDK on Windows 7 64-Bit
提问by Luke Shaheen
I've looked in numerous threads here and on Google and cannot find a solution.
我在这里和谷歌上查看了许多线程，但找不到解决方案。
I've installed the latest version of Java JDK (1.6.0_26) on my 64-bit Windows 7. I've added the file path "C:\Program Files (x86)\Java\jdk1.6.0_26" to JAVA_HOME, and added "C:\Program Files (x86)\Java\jdk1.6.0_26\bin" to the CLASSPATH and PATH variables. I've restarted my machine. But, I when I go to to run javac -version from the command line, I receive the error
我已经在我的 64 位 Windows 7 上安装了最新版本的 Java JDK (1.6.0_26)。我已经将文件路径“C:\Program Files (x86)\Java\jdk1.6.0_26”添加到 JAVA_HOME，并将“C:\Program Files (x86)\Java\jdk1.6.0_26\bin”添加到 CLASSPATH 和 PATH 变量中。我已经重新启动了我的机器。但是，当我从命令行运行 javac -version 时，我收到错误
'javac' is not recognized as an internal or external command, operable program or batch file.
Please let me know what I should do! I'm attempting to use Appcelerator's Titanium but it requires a valid path for javac. Thanks!
请让我知道我该怎么做！我正在尝试使用 Appcelerator 的 Titanium，但它需要一个有效的 javac 路径。谢谢！
For reference, here is my PATH variable.

The error is just what it says. javacis not found on the path.(This issue has nothing to do with Java, rather windows cannot find the unqualified executable in the current path or search "PATH" paths.)
错误正是它所说的。javac在路径上找不到。（此问题与Java无关，而是windows无法在当前路径中找到不合格的可执行文件或搜索“PATH”路径。）
Locate the javacfile manually. Verify it can be run with the found path.
javac手动定位文件。验证它可以使用找到的路径运行。
Ensure the path is put in PATH environment variable correctly (it mustbe separated from other entries with a semi-colon (;)). The CLASSPATH is not relevant here. Depending on how PATH is set, it may require restartingthe windows shell (e.g. log out and log back in). Verify the new PATH is correct with echo %PATH%from a console.
确保路径正确放入 PATH 环境变量中（它必须与其他条目用分号 ( ;)分隔）。CLASSPATH 在这里不相关。根据 PATH 的设置方式，可能需要重新启动windows shell（例如注销并重新登录）。echo %PATH%从控制台验证新的 PATH 是否正确。
Run javacand verify it is executed.
运行javac并验证它已执行。
Happy coding.
快乐编码。

I was facing the same problem, I set the path in command line:
我遇到了同样的问题，我在命令行中设置了路径：
set path = "c:/...."
设置路径 = "c:/...."
but it was not recognized as path, than I checked my Windows type (x64) and Java type (x64). Then I set the path manually in system variables in the properties of My computer and re-opened the cmd prompt, it worked.
但它未被识别为路径，而不是我检查了我的 Windows 类型 (x64) 和 Java 类型 (x64)。然后我在我的电脑属性中的系统变量中手动设置路径并重新打开cmd提示符，它起作用了。
