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获得本教程的工作版本。 视觉工作室代码。

我正在尝试通过安装camelot 。 VSCode ，使用诗歌，但有依赖问题。

这适用于Jupyter Notebooks （帖子底部），但我正在尝试将 append 转换为 existing.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 ：

danielbellhv@PF2DCSXD:/mnt/c/Users/dabell/Documents/GitHub/workers-python/workers/data_simulator/src$ pip install camelot

尝试的解决方案：

我在 Jupyter Notebook 中得到了 Ghostscript 文件路径 output。

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 output，我需要“将新位置附加到 PATH 变量” 。

但是，这仍然行不通。 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'

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，然后返回到您的第一个 python 版本后在其上安装模块。 更改 python 版本以工作新安装的模块
