我不想在python中使用pdfbox，我已使用此https://pypi.org/project/python-pdfbox/安装，但是当我尝试运行p = pdfbox.PDFBox()时，我收到了以下错误。

Traceback (most recent call last):

知道如何在ubuntu中使用PDFBOX吗？

所以，现有的发行版似乎已经过时了：

  1. 最新版本为2.0.9，2.0.8的链接已不存在
  2. 代码尝试通过下载当前版本不再存在的md5文件来验证程序包的完整性。

    3. 我冒昧地分配现有的回购并实施补丁。可以找到此包装器的工作版本here。

    要使用pip从我的存储库安装，请按照发布的here指示进行操作。或者，下载源并在目录中运行namespace Data_Consistency { public partial class MainWindow : System.Windows.Window { Excelhelper g_objExcelHelper = new Excelhelper(); public MainWindow() { InitializeComponent(); } private void tb_TextChanged(object sender, TextChangedEventArgs e) { } private void Browse_Click(object sender, RoutedEventArgs e) { try { OpenFileDialog openFileDialog1 = new OpenFileDialog(); openFileDialog1.InitialDirectory = @"C:\"; openFileDialog1.Title = "Browse Text Files"; bool? l_dialogResult = openFileDialog1.ShowDialog(); if (l_dialogResult.HasValue && l_dialogResult.Value) { tb.Text = openFileDialog1.FileName; string filepath = tb.Text; string file_ext = System.IO.Path.GetExtension(filepath); string l_connection = ""; string l_selectedSheet = cb.Text; string l_inputSheetRange = tb1.Text; string l_connectionString = ""; string l_filePath = tb.Text; string l_fileExt = System.IO.Path.GetExtension(l_filePath); /* Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application(); string workbookPath = l_filePath; Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath); Worksheet xlWorksheet = excelWorkbook.Sheets[1]; Range cells = xlWorksheet.Cells; cells["A:AZ"].NumberFormat = "@"; excelWorkbook.Save();*/ if (file_ext == ".xlsx" || file_ext == ".xls" || file_ext == ".xlsm") { if (file_ext == ".xls") l_connection = @"Provider=Microsoft.ACE.OLEDB.4.0;Data Source=" + l_filePath + ";Extended Properties='Excel 8.0;HDR=NO;IMEX=1';"; else { l_connection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"; l_connection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;MAXSCANROWS=0'"; } Excelhelper ex = new Excelhelper(); string[] sheetnames = ex.GetExcelSheetNames(l_connection); foreach (string item in sheetnames) { if (!item.EndsWith("$'") && !item.EndsWith("$")) continue; string l_item = item.Substring(0, item.IndexOf("$")); if (l_item.StartsWith("'")) { l_item = item.Substring(1, item.IndexOf("$") - 1); } cb.Items.Add(l_item); } } else { MessageBox.Show("please select the file."); } } } catch (NullReferenceException ex) { MessageBox.Show("DialogResult Value is null", "Data Consistency Tool", MessageBoxButton.OK, MessageBoxImage.Information); } } private void tb1_TextChanged(object sender, TextChangedEventArgs e) { } private void Apply_Click(object sender, RoutedEventArgs e) { string l_selectedSheet = cb.Text; string l_inputSheetRange = tb1.Text; string l_connectionString = ""; string l_filePath = tb.Text; string l_fileExt = System.IO.Path.GetExtension(l_filePath); if (l_fileExt.CompareTo(".xls") == 0) l_connectionString = @"provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + l_filePath + ";Extended Properties='Excel 8.0;HRD=NO;IMEX=0';ImportMixedTypes=Text"; else { l_connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"; l_connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;MAXSCANROWS=0'"; } g_objExcelHelper.g_objDtInput = g_objExcelHelper.GetDataTable(l_connectionString, l_selectedSheet, l_inputSheetRange, g_objExcelHelper.g_objDtInput); } private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { } private void tb2_TextChanged(object sender, TextChangedEventArgs e) { } private void ApplyButton_Click_2(object sender, RoutedEventArgs e) { string l_selectedSheet = cb1.Text; string l_inputSheetRange = tb3.Text; string l_connectionString = ""; string l_filePath = tb2.Text; string l_fileExt = System.IO.Path.GetExtension(l_filePath); if (l_fileExt.CompareTo(".xls") == 0) l_connectionString = @"provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + l_filePath + ";Extended Properties='Excel 8.0;HRD=NO;IMEX=0';ImportMixedTypes=Text"; else { l_connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"; l_connectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + l_filePath + ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1;MAXSCANROWS=0'"; } g_objExcelHelper.g_objDtInput = g_objExcelHelper.GetDataTable(l_connectionString, l_selectedSheet, l_inputSheetRange, g_objExcelHelper.g_objDtInput); } private void tb3_TextChanged(object sender, TextChangedEventArgs e) { } private void Search_Button_Click(object sender, RoutedEventArgs e) { try { OpenFileDialog openFileDialog1 = new OpenFileDialog(); openFileDialog1.InitialDirectory = @"C:\"; openFileDialog1.Title = "Browse Text Files"; bool?

    运行代码对我有用：

    python setup.py install

答案 1 :(得分：1)

添加此答案，因为对于初次安装此工具的人来说还不完整。

执行pip install python-pdfbox指向项目https://pypi.org/project/python-pdfbox/，这是预期的行为。

用法说明指示要实例化pdfbox对象，例如：p = pdfbox.PDFbox()。

在这一点上，我们中一些寻求答案的人可能在此问题中遇到了HTTP错误。

查看存储库，请注意要下载的pdfbox版本为hardcoded。这意味着pip安装此软件包的任何人都必须足够“幸运”，才能使apache pdfbox（这是一个Java库）的版本与此版本相同。

解决方案：

免责声明：我试图使此功能适用于Windows 10。

程序包初始化在environment variable上查找pdfbox-app。如果找不到，它将尝试下载一个。因此是错误。

  1. 从pdfbox apache下载最新的pdfbox-app-{version}.jar。
  2. 设置PDFBOX的环境变量，例如set PDFBOX=C:\Dev\pdfbox-app-2.0.11.jar
  3. 启动新命令行，然后尝试：
    • import pdfbox
    • p = pdfbox.PDFBox()
    • p.extract_text("some_filename")

注意事项：extract_text（）无法识别带有空格的空格文件名，
