python - 当我的脚本导入模块 pikepdf 和 pdfminer3 时如何修复 pyinstaller 'no module named...' 错误？

Question

我已经使用 PikePDF 和 PDFminer3 构建了一个有效的 py 脚本，它将从我的桌面上提取一个 PDF，并用可用的文字创建一个 txt 文件。

这样做的目的是帮助我的工作团队修改法律文件，这些文件通常无法复制粘贴进行修改(因此必须手动打印)。由于我的大多数同事都反对设置 anaconda 和使用 python，所以我想使用 pyinstaller 将我的脚本转换为 .exe。

当我运行由 pyinstaller 创建的应用程序时，我能够在出现此错误之前完成一些初步输入:

    Traceback <most recent call last>:
      File 'PDF2TEXT.py', line 35, in <module>
    ModuleNotFoundError: No module named 'pikepdf._cpphelpers'
    (10688) Failed to execute script PDF2TEXT

在编译 pyinstaller 的过程中，我还连续收到很多关于丢失 anaconda3 dll 文件的警告:

Warning: lib not found: msmpi.dll dependency of c:\users\anejar1\appdata\local\continuum\anaconda3\Library\bin\mkl_blacs_mspi_ilp64.dll

我已经做了一些挖掘并在其他线程上应用了一些解决方案但没有成功，包括运行:

pyinstaller --path= [path to pikepdf] --path= [path to pdfminer3] -F PDF2TEXT.py

和

pyinstaller --hidden-import=pikepdf --hidden-import=pdfminer3 -F PDF2TEXT.py

底层代码非常短(并且工作正常)并且只从 pikepdf、pdfminer 和 os 导入:

"""
from pdfminer3.layout import LAParams, LTTextBox, LTTextLine
from pdfminer3.pdfpage import PDFPage, PDFTextExtractionNotAllowed
from pdfminer3.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer3.converter import PDFPageAggregator
from pdfminer3.pdfparser import PDFParser
from pdfminer3.pdfdocument import PDFDocument
from pdfminer3.pdfdevice import PDFDevice
import io
import os
import pikepdf

print('Enter your CBA User ID:')
CBAusername = input()
print('\nEnter the name of your PDF:')
FileName = input()

#############################

base_path = "C:/Users/" + CBAusername + "/Desktop"
pike_path = "C:/Users/" + CBAusername + "/AppData/Roaming/Python/Python36/PikePDF"
my_file = os.path.join(base_path + "/" + FileName + ".pdf")
my_extractable_file = os.path.join(pike_path + "/" + "PikedPDF2TEXT.pdf")
log_file = os.path.join(base_path + "/" + "PDF2TEXT.txt")

password = ""
extract = ""

pdf = pikepdf.open(my_file)
pdf.save(my_extractable_file)

fp = open(my_extractable_file, "rb")
parser = PDFParser(fp)
document = PDFDocument(parser, password)

if  not document.is_extractable:
   raise PDFTextExtractionNotAllowed

rsrcmgr = PDFResourceManager()
laparams = LAParams()

device = PDFPageAggregator(rsrcmgr, laparams=laparams)

interpreter = PDFPageInterpreter(rsrcmgr, device)

for page in PDFPage.create_pages(document):
    interpreter.process_page(page)
    layout = device.get_result()
    for lt_obj in layout:
        if isinstance(lt_obj,LTTextBox) or isinstance(lt_obj, LTTextLine):
            extract += lt_obj.get_text()

fp.close()

print(extract.encode("utf-8"))

with open(log_file, "wb") as my_log:
    my_log.write(extract.encode("utf-8"))
    print ("Done !!")

我找到了这个错误的解决方案:

No module named 'pikepdf._cpphelpers'

只需添加:

from pikepdf import _cpphelpers

到你的脚本的顶部
