Python tabla模块中的这个错误是什么？

Question

我一直有这个错误。我正在努力-

麦克塞拉10.8

Python3.6.2

表1.0.5

Traceback (most recent call last):
  File "/Users/Sam/Desktop/mitch test/test.py", line 22, in <module>
    tabula.convert_into(root.fileName, "_ExportedPDF-" + date_time + ".csv", output_format="csv", pages="all")
AttributeError: module 'tabula' has no attribute 'convert_into'

这是给我一个错误的代码。

tabula.convert_into(root.fileName, "_ExportedPDF-" + date_time + ".csv", output_format="csv", pages="all")

---

更新：

当我试图做from tabula import wrapper时，我得到了这个错误：

ImportError: cannot import name 'wrapper'

更新：

根据@L.Alvarez修正注释

获取以下错误：

Answer 1

CalledProcessError:Command'['java'，'-jar'，'/lib/python2.7/site packages/tabla/tabla-1.0.1-jar-with-dependencies.jar'，'--pages'，'1'，'--guess'，]'返回非零退出状态1

如果出现上述错误，则意味着您必须安装java jre和java jdk

sudo apt-get install default-jre

sudo apt-get install default-jdk

如果上述安装工作正常，您可以按照此处的步骤操作 https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-get-on-ubuntu-16-04

Answer 2

我怀疑你安装了一个版本为1.0.5的pip install tabula库。这是the github repo。它没有转换成函数

但实际上您打算安装this tabula，其最新版本是0.9.0

你应该pip uninstall tabula和pip3 install tabula-py
