Python tabula模块中的这个错误是什么？

Question

我一直收到这个错误。我正在努力 -

Mac Sierra 10.8

Python 3.6.2

tabula 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'

这是我的错误代码。

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

更新：

当我尝试from tabula import wrapper时，我得到错误：

ImportError: cannot import name 'wrapper'

更新：

Answer 1

我怀疑你做了pip install tabula，它安装了一个版本为1.0.5的tabula库。这是the github repo。它没有convert_into函数

但实际上你打算安装this tabula，其最后一个版本是0.9.0

您应该pip uninstall tabula和pip3 install tabula-py

Answer 2

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

如果您遇到上述错误，则表示您必须安装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
