※ 引述《PiGFAcE (被遗忘在沙滩上的脚印)》之铭言： : 我知道装完以後 要去多改一行环境设定 : 把 windows 中的环境改成 j2se 所在的位置 : 之前装的时候 装完以後 发现虽然我的 java javac 在 console 端可以跑 : 但是很多 windows 内建 放在 system32 下的指令 都不能在 console 端下了 : 是我之前设定错了吗 : 还是本来就是这样的 : 有办法并存吗 : 因为还蛮常用到一些 system32 下的指令的 http://lmgtfy.com/?q=windows+path+environment+variable Top Result: http://vlaurie.com/computers2/Articles/environment.htm The PATH Environment Variable The path to a file is basically its address on the computer. It tells programs how to find a file. It is the drive plus any directories and sub-directories where the file is located. The %PATH% environment variable specifies the command search path. Typically, this is a group of directories where executable files that are repeatedly used are to be found. Examples of the default values are listed in the first table above; in this case, they are the Windows directory and two of its important system sub-directories. To see what is in the PATH variable on a computer, open a command window and enter "echo %PATH%".
