setx语法无效 [英] Invalid syntax with setx

问题描述

我使用 setx 命令设置 OGRE_HOME ：

setx OGRE_HOME D:\Program Files\OgreSDK

现在我需要更改为 OGRE_HOME 的值。
如何搜索我设置的所有值？
如果我再次运行命令，它显示：

Now I need to change to value of OGRE_HOME. How can I search all the values I have set? If I run the command again, it shows that:

ERROR: Invalid syntax. Default option is not allowed more than '2' time(s).

推荐答案

您的Ogre SDK路径有空格它被解释为另一个参数的分隔符。将围绕您的路径，将其作为 setx 的一个参数：

Your path to the Ogre SDK has a space character in it, which is interpreted as a delimiter to another argument. Surround your path with " to keep it as one single argument to setx:

setx OGRE_HOME "D:\Program Files\OgreSDK"

要查看 OGRE_HOME 环境变量的当前值：

To see the current value of the OGRE_HOME environment variable:

echo %OGRE_HOME%

您可能需要打开一个新的命令提示符才能看到如果你设置它，然后尝试立即看到它的价值。

You may have to open a new command prompt shell to see the value if you set it and are then trying to immediately see it's value.

要查看所有当前设置的环境变量，只需运行：

To see all currently set environment variables, simply run:

set

仅显示环境具有特定前缀的变量（因此 FOO 将显示 FOOBAR 和 FOOBAZ ），将该前缀放在设置之后：

To show only environment variables that have a certain prefix (so FOO would show FOOBAR and FOOBAZ), put that prefix after set:

set PREFIX

或者，您可以使用GUI编辑环境变量（假设Windows 7在这里）。

Alternatively, you can use the GUI to edit environment variables (assuming Windows 7 here).

• 右键单击计算机，选择属性


• 点击左窗格中的高级系统设置


• 确保您位于高级选项卡在弹出的对话框


• 点击底部
$ 环境变量...

• Right-click Computer, choose Properties
• Click Advanced system settings in the left pane
• Make sure you're on the Advanced tab in the pop-up dialog
• Click Environment Variables... at the bottom

一个对话框将弹出用户特定的环境变量以及系统环境变量。选择一个值并使用新建/编辑/删除按钮与它们进行交互。

A dialog will pop up with your user-specific environment variables as well as your system-wide environment variables. Select a value and use the New/Edit/Delete buttons to interact with them.
