从.bat文件运行python脚本并使用Powershell

I run several python scripts on my W10 server and I'm looking for a way to open them all together.

我在我的W10服务器上运行了几个python脚本,我正在寻找一种方法来打开它们。

I run manually my scripts opening a PowerShell on the script folder and executing pythonw script.py

我手动运行脚本在脚本文件夹上打开PowerShell并执行pythonw script.py

I have tried several ways, with no result...

我尝试了几种方法,没有结果......

PowerShell -NoProfile -ExecutionPolicy Bypass -Command "& 'C:\Users\pc2\AppData\Local\Programs\Python\Python36-32\pythonw.exe C:\Users\pc2\script.py'"

also tested:

powershell.exe -noexit -command "'pythonw C:\Users\pc2\script.py'"

And:

powershell -command "& {&'C:\Users\pc2\AppData\Local\Programs\Python\Python36-32\pythonw.exe ' C:\Users\pc2\script.py}"

None of the above does anything... they should be opening the script.py file in using pythonw.

以上都没有做任何事......他们应该在使用pythonw时打开script.py文件。

Can anyone point me in the correct direction to get this done?

有人能指出我正确的方向来完成这项工作吗?

To execute a single script:

要执行单个脚本:

powershell -c "pythonw 'C:\Users\pc2\script1.py'"

^{Note: The enclosing '...' around the file path are only needed if the latter contains shell metacharacters such as whitespace.
Alternatively, use ""..."" when calling from cmd.exe (batch file), and `"...`" when calling from PowerShell.}

注意:仅当后者包含shell元字符(如空格)时,才需要在文件路径周围包含“...”。或者,在从cmd.exe(批处理文件)调用时使用“”...“”,在从PowerShell调用时使用“...”。

To execute multiple scripts, in sequence:

要按顺序执行多个脚本:

powershell -c "& { $Args | % { pythonw $_ } } 'C:\Users\pc2\script1.py' 'C:\Users\pc2\script2.py'"

^{Note: This only works when calling from cmd.exe (batch file).
(From within PowerShell, simply execute what's inside "..." directly)}

注意:这仅在从cmd.exe(批处理文件)调用时有效。 (从PowerShell中,直接执行“...”内部的内容)

As for what you tried, focusing just on what command string PowerShell ended up seeing:

至于你尝试过的,只关注PowerShell最终看到的命令字符串:

& 'C:\Users\pc2\AppData\Local\Programs\Python\Python36-32\pythonw.exe C:\Users\pc2\script.py'

&'C:\ Users \ pc2 \ AppData \ Local \ Programs \ Python \ Python36-32 \ pythonw.exe C:\ Users \ pc2 \ script.py'

The problem is that you're passing the entire command line to &, whereas it only expects the executable name;
C:\Users\pc2\AppData\Local\Programs\Python\Python36-32\pythonw.exe C:\Users\pc2\script.py is obviously not a valid executable name / path.

问题是你将整个命令行传递给&,而它只需要可执行文件名; C:\ Users \ pc2 \ AppData \ Local \ Programs \ Python \ Python36-32 \ pythonw.exe C:\ Users \ pc2 \ script.py显然不是有效的可执行文件名/路径。

'pythonw C:\Users\pc2\script.py'

By virtue of being enclosed in '...', this is a string literal, which PowerShell simply outputs as such - no command is ever executed.

由于被包含在'...'中,这是一个字符串文字,PowerShell只是这样输出 - 没有执行任何命令。

& {&'C:\Users\pc2\AppData\Local\Programs\Python\Python36-32\pythonw.exe ' C:\Users\pc2\script.py}

&{&'C:\ Users \ pc2 \ AppData \ Local \ Programs \ Python \ Python36-32 \ pythonw.exe'C:\ Users \ pc2 \ script.py}

Since you're using a script block ({ ... }), you're passing C:\Users\pc2\script.py as an argument, so you'd have to refer to it as such inside the block, either via the automatic $Args variable, or via a parameter defined in a param() block.
(As an aside: your file path has an extraneous trailing space, but PowerShell seems to ignore that.)

由于您正在使用脚本块({...}),因此您将C:\ Users \ pc2 \ script.py作为参数传递,因此您必须在块内引用它,或者通过自动$ Args变量,或通过param()块中定义的参数。 (顺便说一下:你的文件路径有一个无关的尾随空间,但PowerShell似乎忽略了这一点。)

#2

From the powershell console itself, you can directly run like this:

从powershell控制台本身,您可以直接运行如下:

PS C:\Python27> python C:\Users\pc2\script.py

If necessary please edit the PATHTEXT environmental variable in the powershell profile:

如有必要,请在powershell配置文件中编辑PATHTEXT环境变量:

$env:PATHEXT += ";.py"

In the batch also you can put the same command to execute the python. Save the file as something.bat :

在批处理中,您也可以使用相同的命令来执行python。将文件另存为something.bat:

python C:\Users\pc2\script.py

Hope it helps.

希望能帮助到你。
