PDF文本Python3.6pdfminer没有名为“pdfminer”的模块

Question

我尝试使用pdfminer.six将一个目录中的多个pdfs转换为多个.txt文件，使用python3.6.3

当运行下面的代码时，我得到了以下错误：ModuleNotFoundError:没有名为'pdfminer'的模块。或者，当我运行pdf2txt.py filename.pdf时，它提供了therenv：\r:没有这样的文件或目录

我对这个问题做了一些研究。我已经删除了原来的pdfminer从我的pip，目前，它只有pdfminer.six在我的pip。此外，我还在虚拟环境下运行python 3.6.3。

下面是我运行的代码：

from io import StringIO
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
import os
import sys, getopt

#converts pdf, returns its text content as a string
def convert(fname, pages=None):
    if not pages:
        pagenums = set()
    else:
        pagenums = set(pages)

    output = StringIO()
    manager = PDFResourceManager()
    converter = TextConverter(manager, output, laparams=LAParams())
    interpreter = PDFPageInterpreter(manager, converter)

    infile = file(fname, 'rb')
    for page in PDFPage.get_pages(infile, pagenums):
        interpreter.process_page(page)
    infile.close()
    converter.close()
    text = output.getvalue()
    output.close
    return text 

#converts all pdfs in directory pdfDir, saves all resulting txt files to txtdir
def convertMultiple(pdfDir, txtDir):
    if pdfDir == "": pdfDir = os.getcwd() + "\\" #if no pdfDir passed in 
    for pdf in os.listdir(pdfDir): #iterate through pdfs in pdf directory
        fileExtension = pdf.split(".")[-1]
        if fileExtension == "pdf":
            pdfFilename = pdfDir + pdf 
            text = convert(pdfFilename) #get string of text content of pdf
            textFilename = txtDir + pdf + ".txt"
            textFile = open(textFilename, "w") #make text file
            textFile.write(text) #write text to text file

pdfDir = "../../data/raw/"
txtDir = "../../data/interim/"
convertMultiple(pdfDir, txtDir)
