从 Windows 命令行启动 Python 脚本:脚本启动，然后失败

本文介绍了从 Windows 命令行启动 Python 脚本:脚本启动，然后失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我是新手，请多多包涵.

I'm a rank novice, please bear with me.

我从另一位工程师那里继承了一个 python 脚本.为方便起见，我希望能够从 Windows bat 文件启动脚本，但最初尝试通过从 Windows 命令行运行来进行调试.

I've inherited a python script from another engineer. For convenience, I want to be able to launch the script from a Windows bat file, but initially am trying to debug by running from Windows command line.

每当我从 CMD 启动脚本时，它似乎启动正常，然后立即失败并出现错误.

Whenever I start the script from CMD, it seems to start OK and then immediately fails with errors.

我的环境:Windows7 Pro 和 Windows10 Pro(出现同样的错误)，Anaconda 3.7 , Spyder 3.3.2

My environment: Windows7 Pro and Windows10 Pro (same errors occur), Anaconda 3.7 , Spyder 3.3.2

当我从内部 Spyder 运行脚本时，脚本运行良好，没有错误.

When I run the script from inside Spyder, script runs fine, no errors.

当我尝试从 Windows CMD 运行时:

When I try running from Windows CMD:

  C:Windowssystem32>  "%programdata%Anaconda3python.exe"   "B:IcCharDataB1505_Process_Data_20190214.py"

我收到以下错误:

Traceback (most recent call last):
  File "B:IcCharDataB1505_Process_Data_20190214.py", line 21, in <module>
    import pandas as pd # Dataframe library
  File "C:ProgramDataAnaconda3libsite-packagespandas\__init__.py", line 19, in <module>
    "Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

下面是脚本的第一部分，带有实际的 #s 行，错误似乎源于此.互联网搜索无果.

Below is the first part of the script, with actual line #s, where errors seem to be originating.Internet searches have been fruitless.

可能是什么问题?
同样，请注意脚本在 Spyder 内部运行良好

What could be the problem(s)?
Again, note the script runs fine from inside Spyder

import sys
print(sys.path)
