ModuleNotFoundError：没有名为“camelot”的模块 |适用于 Jupyter Notebooks 但不适用于 VSCode

Question

目标：通过PDF 获得此tutorial 的工作版本。 Visual Studio 代码。

我正在尝试通过安装camelot。 VSCode，使用 Poetry，但存在依赖问题。

这适用于 Jupyter Notebooks（帖子底部），但我正在尝试附加到现有的 .py 项目。

代码：

import glob
import camelot
import pandas as pd
import multiprocessing.dummy as mp

import ctypes
from ctypes.util import find_library
find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))


PDF_LIST = glob.glob('../data/gri/reports/*.pdf')

def scrape_tables(pdf_filename):
    tables = camelot.read_pdf(pdf_filename)
    print("Total tables extracted:", tables.n)
    return tables

p = mp.Pool(len(PDF_LIST))
pdf_esg_scraped = p.map(scrape_tables, PDF_LIST)

pip install camelot-py:

Traceback (most recent call last):
  File "scrape_tables.py", line 25, in <module>
    import camelot
ModuleNotFoundError: No module named 'camelot'

pip install camelot:

尝试的解决方案：

我在 Jupyter Notebook 中得到了 Ghostscript 文件路径输出。

import ctypes
from ctypes.util import find_library
find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))
>>> 'C:\\Users\\me\\Anaconda3\\Library\\bin\\gsdll64.dll'

使用这个输出，我需要"append new location to the PATH variable"。

但是，这仍然不起作用。我尝试过的变体：

PATH=$PATH:C:\Users\me\Anaconda3\Library\bin\gsdll64.dll
PATH=$PATH:C:\\Users\\me\\Anaconda3\\Library\\bin\\gsdll64.dll
PATH=$PATH:'c/Users/me/Anaconda3/Library/bin/gsdll64.dll'
PATH=$PATH:'/mnt/c/Users/me/Anaconda3/Library/bin/gsdll64.dll'

export PATH="$HOME/.poetry/bin:$PATH";C:/Users/me/Anaconda3/Library/bin/gsdll64.dll
bash: C:/Users/me/Anaconda3/Library/bin/gsdll64.dll: No such file or directory

此外，为了让 Poetry 工作，我需要让PATH 指向它的位置：

export PATH="$HOME/.poetry/bin:$PATH"

我可以有多个PATH 变量吗？

有时在 VSCode 中安装了模块但它无法识别新模块，在 VSCode 的左侧按钮中单击 python 版本并将其更改为另一个版本，然后在返回到您的第一个 python 版本后安装模块在上面。
