Java命令有效，但javac命令无效 [英] Java command works but javac command doesn't
问题描述
我只在Windows中安装了jdk和jre版本8.环境变量已设置.我尝试运行"java -version"在cmd中，它显示已安装的Java的版本.但是，当我尝试使用"javac projectName"编译Java项目时，系统说javac不被识别为内部或外部命令.那么有人可以告诉我如何解决它吗?
I just install jdk and jre version 8 In windows. Environment variable already set. I try run "java -version" in cmd and it shows the version of java installed. But when I try to compile java project with "javac projectName" system says javac is not recognized as internal or external command. So can anyone tell me how to fix it?
这是我的环境变量:

推荐答案
变量路径中有错字:
C:\Program File\Java\jdk1.8.0_60\bin;C:\Program File\Java\jdk1.8.0_60\bin\;
应该并且您不需要两次
C:\Program Files\Java\jdk1.8.0_60\bin;
