How can I make a program runnable from the commandline without typing its full path?
提问by soapergem
I can best explain my question with an example. I recently downloaded Python for Windows, installed to C:\Python. So if I'm in folder X that contains myscript.py, and I want to invoke it, I have to call this:
我可以用一个例子来最好地解释我的问题。我最近下载了适用于 Windows 的 Python，安装到 C:\Python。因此，如果我在包含 myscript.py 的文件夹 X 中，并且我想调用它，我必须调用它：
> C:\Python\python.exe myscript.py
But it would be super-cool if I could just do this, from within anyfolder:
但是，如果我可以从任何文件夹中执行此操作，那就太酷了：
> python myscript.py
How do I make that "global"?
我如何使这个“全球”？

You just need to add the path C:\Pythonto your PathEnvironment Variable which can be modified from the Advancedtab of the System Propertiescontrol panel.
您只需要将路径C:\Python添加到您的路径环境变量中，该变量可以从系统属性控制面板的高级选项卡中进行修改。

To eliminate the need to type pythonbefore your script, you can do the following:
要消除在python脚本之前键入的需要，您可以执行以下操作：
- Add
python.exeto your system PATH environment variable, if it's not already there. - Add
;.pyto the end of your PATHEXT system environment variable.
- 添加
python.exe到您的系统 PATH 环境变量中（如果它尚未存在）。 - 添加
;.py到 PATHEXT 系统环境变量的末尾。
Then, instead of typing
然后，而不是键入
> C:\Python\python.exe myscript.py
or
或者
> python myscript.py
you can just type
你可以输入
> myscript.py

Another possible solution would be to add an entry to the registry:
另一种可能的解决方案是在注册表中添加一个条目：
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\python.exe
and then set the (default)value of that to the path (+ program name) where your python.exe resides, e.g. C:\Python\Python.exe.
然后将其(default)值设置为您的 python.exe 所在的路径（+ 程序名称），例如C:\Python\Python.exe.
That way, you can call python.exe from anywhere - no path or other stuff needed.
这样，您可以从任何地方调用 python.exe - 不需要路径或其他东西。
