我正在尝试使用 pyinstaller 构建一个使用 pytesseract OCR 的单文件 EXE。 .exe 文件将在多台 PC 上使用。 假设这是我的 .py 代码，我想将其转换为 .exe
import cv2
import os
import ast
import sys
def OCR():
#pytesseract.pytesseract.tesseract_cmd = r'C:\Users\user\AppData\Local\Programs\Tesseract-OCR\tesseract.exe'
pytesseract.pytesseract.tesseract_cmd = resource_path('tesseract.exe')
#Replace with random jpeg or png file
image = cv2.imread(r'C:\Users\user\Downloads\IMG_1.JPG')
Read = pytesseract.image_to_string(image, config='--psm 11')
print(Read)
def resource_path(relative_path):
if hasattr(sys, "_MEIPASS"):
return os.path.join(sys._MEIPASS, relative_path)
return os.path.join(relative_path)
OCR()
还有 .spec 文件
# -*- mode: python ; coding: utf-8 -*-
block_cipher = None
a = Analysis(
['C:\\Users\\user\\AppData\\Local\\Microsoft\\WindowsApps\\pythonProject3\\SimpleOCR.py'],
pathex=[],
binaries=[(r'C:\\Users\\user\\AppData\\Local\\Programs\\Tesseract-OCR\\tesseract.exe', 'tesseract.exe') ],
datas=[],
hiddenimports=[],
hookspath=[],
hooksconfig={},
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher,
noarchive=False,
)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)
exe = EXE(
pyz,
a.scripts,
a.binaries,
a.zipfiles,
a.datas,
[],
name='SimpleOCR',
debug=False,
bootloader_ignore_signals=False,
strip=False,
upx=True,
upx_exclude=[],
runtime_tmpdir=None,
console=True,
disable_windowed_traceback=False,
argv_emulation=False,
target_arch=None,
codesign_identity=None,
entitlements_file=None,
)
创建 .exe 文件并运行它后，尝试使用 pytesseract 时出现错误：PermissionError – [WinError 5] 访问被拒绝`导致无法使用 OCR。
有什么想法吗？

正如我的评论中提到的，我不知道可执行文件是否具有一些必须与其相关的依赖项。这就是为什么我会尝试捆绑该文件夹的全部内容而不是仅捆绑 exe。 要实现此目的，请更新以下两行。
return os.path.join(sys._MEIPASS, 'Tesseract-OCR', relative_path)
binaries=[(r'C:\\Users\\user\\AppData\\Local\\Programs\\Tesseract-OCR', 'Tesseract-OCR')],
编辑：
在当前的实现中，您将图像硬编码为
image = cv2.imread(r'C:\Users\user\Downloads\IMG_1.JPG')
这就是为什么可执行文件只能在您的电脑上运行。如果保留如上所示的行，则文件必须始终位于该位置。 我建议做这样的事情。
import os
import sys
execution_path = os.path.dirname(sys.argv[0])
image = os.path.join(execuation_path, 'IMG_1.JPG')
使用这种方法，只需保留相对于可执行文件名为“IMG_1.JPG”的图像，它就应该可以工作。
编辑2：
通过将函数 ocr 的 try/ except 情况下的图像打印到控制台来检查您创建的图像路径是否有效且绝对。确保使用 console True 进行编译，以便获得输出。这不是一种很好的调试方式，但它应该可以完成工作。
