Python 表格模块中的这个错误是什么？

Question

我一直收到这个错误。我正在研究 -

Mac 塞拉利昂 10.8

Python 3.6.2

表格 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'

我的代码出错了。

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

更新：

当我尝试执行 from tabula import wrapper 时出现错误：

ImportError: cannot import name 'wrapper'

更新：

根据@L 修正评论。阿尔瓦雷斯

出现以下错误：

Answer 1

我怀疑你 pip install tabula 安装了一个 tabula 版本为 1.0.5 的库。这里是 the github repo。它没有 convert_into 函数

但你实际上是想安装 this tabula，其最新版本是 0.9.0

你应该 pip uninstall tabula 和 pip3 install tabula-py

Answer 2

CalledProcessError: 命令'['java', '-jar', '/lib/python2.7/site-packages/tabula/tabula-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

如果以上安装成功，您可以按照这里的步骤操作 https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-get-on-ubuntu-16-04
