问题描述

我有一种情况，我必须在 NSSM 中将 python.exe 作为服务运行.为了测试，我创建了 .exe 文件，其中只有 import pandas as pd .我在 NSSM 中成功创建了服务.但是当我启动该服务时出现错误 windows 无法在本地计算机上启动该服务该服务没有返回错误.

I have a situation where i have to run a python.exe as a service in NSSM. To test, I have created .exe file which has only import pandas as pd in it. I created the service in NSSM successfully. But when I start the service I get error windows could not start the service on local computer the service did not return an error.

我还能做些什么来解决这个问题?

What else can I do to tackle this problem?

相信我，我已经尝试过堆栈溢出的所有解决方案.

Trust me I have tried all solutions in stack overflow.

1. 我在启动服务时关闭了 cmd.
2. 将所有控制权交给网络服务

推荐答案

1. 在 Program Files 或其他公共文件夹(如果尚未安装)中安装 Python.

1. Install Python in Program Files or another public folder if not already.

如果您的服务作为 NETWORK SERVICE 运行，请使用 psexec 作为网络服务:

If your service are running as the NETWORK SERVICE run CMD with psexec as the NETWORK SERVICE:

 psexec -i -u "nt authority\network service" cmd.exe

使用此 cmd 安装 pandas.

在cmd中检查你是否可以运行python并导入pandas.

In cmd check if you can run python and import pandas.

由于服务不能有窗口，所以您需要以某种方式检查程序的结果.例如将异常重定向到文件:

Since services can't have windows you need to somehow check result of your program. For example redirect exception to a file:

 try:
     import pandas
     # do something
 except Exception as e:
     with open(r'c:/service_output.txt', 'wt+') as fd:
         fd.write(repr(e))
