python tabula-py不会读pdf

Question

我试图从一系列PDF文件中提取表格，但无法使表格工作。我一直试图通过Windows操作系统上的Jupyter笔记本使用它。不幸的是，我也得到了同样的结果

“FileNotFoundError”

每次我尝试使用read_PDF（）。

从我到目前为止在网上发现的情况来看，这个错误似乎是在试图运行Tabula java文件时产生的。我已经正确安装了java。

在此方面的任何帮助都将不胜感激。

这是我试图运行的代码：

    from tabula import read_pdf
    df = read_pdf("https://github.com/tabulapdf/tabula-java/raw/master/src/test/resources/technology/tabula/arabic.pdf")

错误消息：

要确保Windows可以找到Java编译器和解释器：选择开始-

[在Windows XP中，选择开始-

前置C:\Program Files\Java\jdk1。6.0_27\bin；指向路径变量的开头。单击“确定”三次。

Answer 2

我在没有为java设置路径环境的情况下重现了这个问题。exe。确保为Java设置路径。另见：https://www.java.com/en/download/help/path.xml
