python - 从 Windows 命令行 : script starts, 启动 Python 脚本失败

Question

我是新手，请多多包涵。

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。

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。

我的环境: Windows7 Pro和Windows10 Pro(出现同样的错误)， 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。

当我尝试从 Windows CMD 运行时:

  C:\Windows\system32>  "%programdata%\Anaconda3\python.exe"   "B:\IcCharData\B1505_Process_Data_20190214.py"

我收到这些错误:

Traceback (most recent call last):
  File "B:\IcCharData\B1505_Process_Data_20190214.py", line 21, in <module>
    import pandas as pd # Dataframe library
  File "C:\ProgramData\Anaconda3\lib\site-packages\pandas\__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，其中包含实际的行号，错误似乎源于此。 互联网搜索没有结果。

可能出现什么问题？
再次注意，脚本在 Spyder 内部运行良好

在 Spyder 中运行:

import sys
print(sys.path)

runfile('B:/Desktop/untitled0.py', wdir='B:/Desktop')    # TH: apparently because spyder prompted me to save the script here#
[
'C:\\Users\\th',                 # TH: line not present with Anaconda Prompt#

如果您希望它工作，您的批处理文件需要如下所示:

调用 C:/ProgramData/Anaconda3/Scripts/activate.bat C:/ProgramData/Anaconda3 C:\ProgramData\Anaconda3\python.exe "C:/Users/xxx/Documents/script.py"

希望这有帮助...
