我正在尝试在 python 中使用一些库，但我遇到了 PATH 配置问题。
当我尝试使用 Selenium 和 pdf2image 时会发生这种情况。在这两种情况下，都会有一条消息询问文件夹是否在 PATH 中。我已经检查过了，它们已作为系统变量添加到 PATH 中，如您在屏幕截图中所见。
附加信息：当我打开 Ubuntu 时，会出现附加消息，通知 pyenv 配置错误。这会是我的问题的原因吗？我尝试按照说明更改文件 .zhrc 和 .profile 来修复它（如您在屏幕截图中所见），但它仍然无法正常工作。
pdf2image 示例：
输入
# Import libraries
from PIL import Image
import pytesseract
import sys
from pdf2image import convert_from_path, convert_from_bytes
import os
PDF_file = "caderno2_2020-10-28.pdf"
pages = convert_from_path(PDF_file, 500, poppler_path='C:\Program Files\poppler-0.68.0\bin')
输出
