Docker pandas 阅读 excel

Question

我是Docker的新人，我需要运行一个Flask应用程序，但在这个应用程序中，我需要读取一个xlsx文件。

当我构建 docker 图像时，我有 excel 文件，但 Docker 没有读取它。

使用 xlsx 查看我的代码部分：

try :
    # Page PayPlug
    infos_pay = pd.read_excel('./app-infos.xlsx', sheet_name='payplug')
    secret_key = infos_pay.loc[0].tolist()
    payplug.set_secret_key(secret_key[0])
    # Page mail
    feuille_mail = pd.read_excel('./app-infos.xlsx', sheet_name='mail')
    infos_mail = feuille_mail.loc[0].tolist()
    
except :
    print("Can't read file")

还有我的 docker 文件：

FROM python:3.8

WORKDIR /code

COPY requirements.txt .

RUN pip install -r requirements.txt

COPY . .

CMD [ "python", "./web_AuSpot.py" ]

当我在图像的cli中使用ls cmd时，我看到了xlsx文件，为什么pandas无法读取它？

谢谢，希望我的解释清楚。

Answer 1

pandas 操作不需要读取 excel 个文件。因此，您还需要在需求文件中列出 xlrd 包。如果这不能解决问题，您将需要列出 requirements.txt 文件并添加 docker 错误消息将有助于提出您的问题。

其他可能性是：

可能是文件位置问题。
可能是 pandas 没有作为 pd 导入（我在代码中没有看到它）

Answer 2

我删除了 try expect 并且出现了这个错误：

Traceback (most recent call last):

  File "./web_AuSpot.py", line 46, in <module>
    infos_pay = pd.read_excel('/app-infos.xlsx', sheet_name='payplug')
  File "/usr/local/lib/python3.8/site-packages/pandas/util/_decorators.py", line 296, in wrapper
    return func(*args, **kwargs)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_base.py", line 304, in read_excel
    io = ExcelFile(io, engine=engine)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_base.py", line 867, in __init__
    self._reader = self._engines[engine](self._io)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_xlrd.py", line 21, in __init__
    import_optional_dependency("xlrd", extra=err_msg)
  File "/usr/local/lib/python3.8/site-packages/pandas/compat/_optional.py", line 110, in import_optional_dependency
    raise ImportError(msg) from None
ImportError: Missing optional dependency 'xlrd'. Install xlrd >= 1.0.0 for Excel support Use pip or conda to install xlrd.

(评论里放不下所以放了)

编辑：

我在需求中添加了xrld，更改了xlsx的位置路径，现在我有了这个:

Traceback (most recent call last):
  File "./web_AuSpot.py", line 46, in <module>
    infos_pay = pd.read_excel('app-infos.xlsx', sheet_name='payplug')

    return func(*args, **kwargs)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_base.py", line 304, in read_excel
    io = ExcelFile(io, engine=engine)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_base.py", line 867, in __init__
    self._reader = self._engines[engine](self._io)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_xlrd.py", line 22, in __init__
    super().__init__(filepath_or_buffer)
  File "/usr/local/lib/python3.8/site-packages/pandas/io/excel/_base.py", line 353, in __init__
    self.book = self.load_workbook(filepath_or_buffer)

    return open_workbook(filepath_or_buffer)

    raise XLRDError(FILE_FORMAT_DESCRIPTIONS[file_format]+'; not supported')
