为 Anaconda2 设置 Windows 环境变量时遇到问题

Question

I'm running Anaconda2 on Windows 7 and am having trouble running "python" from the command prompt.

I added "C:\ProgramData\Anaconda2" to PATH in Environment Variables and it allows my to run "python" from CMD. However, this is only true for CMD when I run it by clicking Start, typing cmd, and pressing enter. If I shift+right click from a window and select "Open command window here" and try to run python, I get the error "'python' is not recognized as an internal or external command, operable program or batch file."

For example, in the command windows below, the top one was started by running CMD from the start menu and then running python. The bottom window was opened by shift+right clicking in some location, selecting "Open command window here", then I even changed the directory to match the first window, but you can see "python" wasn't recognized.

Answer 1

1. Uninstall Python.
2. Right click My Computer (Or This PC if Windows 7+) > Properties > Advanced System Settings and click on Environment Variables.
3. In the user variables, select PATH and click on edit.
4. Remove all the Python directories or delete the variable if there are no directories of other programs in the variable.
5. Reinstall Python
