我嘗試在 python 中使用 tabula-module 并使用以下代碼：
import tabula
file = "input.pdf"
tables = tabula.read_pdf(file, pages = "all", multiple_tables = True)
當我嘗試在 Windows 上運行此代碼時，出現此錯誤：
$ python exampleTabula.py

我檢查了 java 安裝并獲取此資訊：
$ which java
/c/Windows/system32/java
和
$ java -version
java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)
要在此配置上使用 tabula，我必須做什么？
uj5u.com熱心網友回復：
根據Tabula-py 的https://pypi.org/project/tabula-py/檔案，我猜您需要 Java 8 。我猜Java版本“1.7.0_80”是Java 7。
請嘗試將 Java 版本更新到 8 并重試。
