执行插图划线.exec文件时出现PyInstaller错误

PyInstaller error when executing Plotly Dash .exec file(执行插图划线.exec文件时出现PyInstaller错误)

问题描述

我正在尝试创建一个.exe文件来运行用Ploly Dash创建的python仪表板。一旦我使用PyInstaller创建文件并尝试运行它，就会收到以下错误：

Traceback (most recent call last):
  File "app.py", line 2, in <module>
  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 967, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 677, in _load_unlocked
  File "/Users/mohamedmartino/opt/anaconda3/lib/python3.7/site-packages/PyInstaller/loader/pyimod03_importers.py", line 623, in exec_module
    exec(bytecode, module.__dict__)
  File "site-packages/dash_core_components/__init__.py", line 12, in <module>

[85571] Failed to execute script app

• 我刚开始编码，我不明白为什么它找不到DCC
  依赖性。有没有更好的方法将我的模块编译成一个
  可执行文件？

我有几个python模块和Excel文件，以及一个包含图像和CSS文件的-ASSET文件夹。

推荐答案

似乎需要修改.spec文件(请参阅下面的sample.spec)。
修改规范文件后，在控制台输入‘pyinstaller*.spec’(似乎‘--onefile’选项不起作用)，即可从浏览器连接您的破折号URL。

#Sample.spec
# -*- mode: python ; coding: utf-8 -*-

#manually add Start to avoid rerusion limit error==>
import sys
sys.setrecursionlimit(5000)
#manually add End<==

block_cipher = None


a = Analysis(['dashtest.py'],
