成功安装后无法识别节点 [英] Node not recognized although successfully installed

问题描述

我尝试在 Windows 7 的全新安装上运行 nodejs . 这就是我所做的:

I try to run nodejs on a brand new installation of Windows 7. This is what I've done:

1. 使用Windows Installer安装节点

1. Install node using the windows installer

确保文件已提取到C:\Program Files (x86)\nodejs\

确保我的Path环境变量包含C:\Program Files (x86)\nodejs\

Make sure that my Path enviorment variable contains C:\Program Files (x86)\nodejs\

打开命令提示符并运行node -v

open up a command prompt and run node -v

这给了我'node is not a recognized ...'-消息.

我在这里想念什么?

更新 运行echo %path%会给我一个不包含C:\Program Files (x86)\nodejs\的目录列表，即使查看系统属性中的环境变量"选项卡也会在路径下显示该目录.太奇怪了.

Update running echo %path% gives me a directory listing that doesn't include C:\Program Files (x86)\nodejs\, even though looking at the "environment variables" tab in the system properties displays it under path. Thats odd.

推荐答案

更新:根据Timos的评论，一种更快的解决方案:重新启动explorer.exe就足够了，您可以在任务管理器中将其停止，然后重新启动".

UPDATE: a quicker solution is per Timos comment: "Restarting explorer.exe is enough, you can stop it in task manager and start it again"

此问题通过重新启动计算机来解决.

This was solved by restarting the computer.

显然，使用节点安装程序可以设置路径，使其在系统属性下可见，但在命令提示符下(运行echo％path％)才可见，直到重新启动计算机.不知道这是Windows还是Node Installer的问题.

Apparently, using the Node installer sets the path so that it is visible under system properties, but not in the command prompt (running echo %path%) until you restart your computer. Not sure if this is a problem with Windows, or the Node Installer.
