pyinstaller .exe在本地工作，但是在被C#调用时失败? [英] pyinstaller .exe works locally but fails when called by C#?

问题描述

我已经使用Python2.7创建了一个脚本，并使用pyinstaller将其编译为同名的exe，在这种情况下，使用--onefile和-w参数将"GeneralStats.py"转换为"GeneralStats.exe"./p>

使用C#调用时，我使用:

  var pythonDirectory =(Directory.GetCurrentDirectory());var filePathExe1 = Path.Combine(pythonDirectory +"\\ Python \\ GeneralStats.exe");Process.Start(filePathExe1); 

在C#外部调用时，因此在我的本地文件中，我可以运行.exe，结果是一个文本文件，其中包含很多值(正确运行).

但是，当以这种格式运行C#时，出现错误消息"GeneralStats返回-1！"

我以前遇到过问题，但这是一个简单的python错误，当我返回代码并运行它时，会收到我忽略的错误.这次，我的python代码未返回任何错误，并且可以在C#之外运行.

关于为什么会这样的任何想法?我可以提供任何必要的代码或文件目录，请问您是否认为这对调试有帮助.

已删除:

  var filePathExe1 = Path.Combine(pythonDirectory +"\\ Python \\ GeneralStats.exe");Process.Start(filePathExe1); 

并替换为:

  ProcessStartInfo _processStartInfo = new ProcessStartInfo();_processStartInfo.WorkingDirectory = Path.Combine(pythonDirectory +"\\ Python");_processStartInfo.FileName = @"GeneralStats.exe";_processStartInfo.CreateNoWindow = true;流程myProcess = Process.Start(_processStartInfo); 

解决方案

您需要为 Process 设置工作目录-它可能正在尝试从其工作目录中加载文件，但不是找到他们.

例如，参见此:

使用 ProcessStartInfo.WorkingDirectory 属性可在启动进程之前进行设置.如果未设置该属性，则默认工作目录为％SYSTEMROOT％\ system32 .

将其设置为 GeneralStats.exe 所在的路径.

I have created a script using Python2.7 and compiled it using pyinstaller into an exe of the same name, in this case "GeneralStats.py" turns into "GeneralStats.exe" using --onefile and -w arguments.

When called with C# I use:

var pythonDirectory = (Directory.GetCurrentDirectory());
var filePathExe1 = Path.Combine(pythonDirectory + "\\Python\\GeneralStats.exe");
Process.Start(filePathExe1);

When called outside of C#, so in my local files I can run the .exe and the result is a text file with lots of values in (Running correctly).

However, when ran with C# in this format, I get an error that "GeneralStats returned -1!"

Which I have had issues with before, but it was a simple python error that when I returned to my code and ran it, I would receive an error that I overlooked. This time my python code returns no errors and works outside of C#.

Any ideas of why this could be? I can provide any code or file directories necessary, please just ask if you feel it would help with debugging.

EDIT:

Solved by removing:

var filePathExe1 = Path.Combine(pythonDirectory + "\\Python\\GeneralStats.exe");
Process.Start(filePathExe1);

And replacing with:

ProcessStartInfo _processStartInfo = new ProcessStartInfo();
_processStartInfo.WorkingDirectory = Path.Combine(pythonDirectory + "\\Python");
_processStartInfo.FileName = @"GeneralStats.exe";
_processStartInfo.CreateNoWindow = true;
Process myProcess = Process.Start(_processStartInfo);

解决方案

You need to set the working directory for the Process - it is probably trying to load files from its working directory but isn't finding them.

See, e.g. this:

Use the ProcessStartInfo.WorkingDirectory property to set it prior to starting the process. If the property is not set, the default working directory is %SYSTEMROOT%\system32.

Set it to the path where GeneralStats.exe is.
