我尝试使用 Tika 运行一个简单的代码解析行来解析 PDF 中的文本（在本例中名为 outputFileName）。这曾经运行没有错误。我最近将我的笔记本电脑送到我们的工作 IT 部门进行软件更新，并且不得不重新安装 Anaconda 并导入某些模块（例如 2019 年 11 月 9 日发布的 Tika 1.22）来运行我的代码。我还从 Tika 导入了 Parser。这是我得到的代码行和错误消息：
代码：
#解析pdf文件中的文本以使用
pdftext = parser.from_file(outputFileName)
错误
AttributeError Traceback (most recent call last)

我还下载了 Java 8。
tika.py 源代码有问题吗？还是我错过了需要安装的东西？任何帮助将非常感激。
