tabula python: Getting subprocess.CalledProcessError: Command '['java', '-Dfile.encoding=UTF8', ERROR
我收到 subprocess.CalledProcessError：命令 '['java'，'-Dfile.encoding=UTF8'，运行 tabula python 库时出错。

Does java -h command work well?; Yes
Ensure your java command is included in PATH Yes
Write your OS and it's version: ? Windows 10
代码：
import tabula
filepath = "C:\Users\himsoni\Desktop\PDF_extraction\black_white_format\black_white_format\PDF_Split_JPEGs\blackwhite.pdf"
df = tabula.read_pdf(filepath, pages = 5 ,guess=True, multiple_tables= True, stream=True, java_options="-Dfile.encoding=UTF8")
print(df)
预期输出：获取特定页面的 table 放置。
我的 PDF 包含此字体描述符对象：
17 0 obj
<</Ascent 891 /CapHeight 662 /Descent -216 /Flags 32 /FontBBox
[-497 -306 1120 1023] /FontFile2 18 0 R /FontName
/AFPTimesNewRoman-Italic /ItalicAngle -17.-21823 /StemV 80 /Type
/FontDescriptor /XHeight 441>>
endobj
根据PDF规范，ItalicAngle必须是一个数字。 -17.-21823 不是有效的数字表示法。因此，不在引擎盖下进行修复的 PDF 解析器很可能无法读取您的文件。 PDFBox 确实失败了。
