pyinstaller -F main.py当我使用 Visual Studio Code 运行代码时，我在构建程序时收到此错误。

我尝试安装 tinycss2pip install但它已经安装了。

我的项目导入是：

from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5 import *
from PyQt5.QtPrintSupport import QPrintDialog, QPrinter
from PyQt5 import uic, QtCore, QtWidgets, QtPrintSupport, QtGui
from functools import partial

from reportlab.graphics import renderPM
from shutil import copyfile
import sys, os, json, cv2, time, threading,ezdxf, imutils
import numpy as np

解决方案

您需要为 和 编写钩子tinycss2，cssselect2因为 PyInstaller 没有正确捆绑它们。

hooks因此，首先，在与您的脚本相同的目录中创建一个名为的目录：

- myfile.py
- hooks
  - hook-cssselect2.py
  - hook-tinycss2.py

然后，在两个钩子文件中——它们必须相同——复制以下文本：

from PyInstaller.utils.hooks import collect_data_files


def hook(hook_api):
    hook_api.add_datas(collect_data_files(hook_api.__name__))

然后，在构建时，添加选项--additional-hooks-dir=hooks.
