1、whl依赖包离线安装?
python -m pip install --upgrade setuptools-51.0.0-py3-none-any.whl
python -m pip install --upgrade pip-20.3.3-py2.py3-none-any.whl python -m pip install certifi-2020.12.5-py2.py3-none-any.whl
python -m pip install chardet-4.0.0-py2.py3-none-any.whl
python -m pip install idna-2.10-py2.py3-none-any.whl
python -m pip install urllib3-1.26.2-py2.py3-none-any.whl?
python -m pip install requests-2.25.1-py2.py3-none-any.whl
python -m pip install lxml-4.6.2-cp36-cp36m-win_amd64.whl

python -m pip install numpy-1.19.4-cp36-cp36m-win_amd64.whl
python -m pip install opencv_python-4.4.0.46-cp36-cp36m-win_amd64.whl2、tar.gz依赖包离线安装
解压之后 cd 进入目录执行?
python setup.py install3、tesseract-ocr安装
Python tesserocr的安装教程：https://jingyan.baidu.com/article/6b18230972e3e6fb59e15909.html
（1）安装时选择多语言数据下载
（2）将?Tesseract-OCR?添加到环境变量
（3）安装成功之后需要将 Tesseract-OCR 根目录下的 tessdata?文件夹复制到 Python?根目录下，否则会出现报错
RuntimeError: Failed to init API, possibly an invalid tessdata path: D:\Python\Python36\Python368\/tessdata/（4）指定变量?tesseract_cmd?为?安装的?tesseract.exe?文件
from PIL import Image
import pytesseract
## 引用 pytesseract 模块需要手动修改 tesseract_cmd 变量的依赖地址
pytesseract.pytesseract.tesseract_cmd = r'D:\Python\install-depend\Tesseract-OCR\tesseract.exe'| 模拟浏览器 | 查看版本 | 镜像地址 | 驱动下载? |
