Question

我正在尝试使用cxfreeze将我的Python脚本构建到.exe文件中。但是，我的脚本使用了一些外部数据文件，这些文件未打包到创建的libary.zip文件中。

例如，我的脚本位于src/，外部数据位于src/data/。我在include_files中指定了build_exe_options属性，但这只将目录和文件复制到构建目录中;它不会将它们添加到library.zip，这是脚本最终查找文件的地方。

即使我进入创建的library.zip并手动添加data目录，我也会收到同样的错误。知道如何让cxfreeze适当地打包这些外部资源吗？

setup.py

from cx_Freeze import setup, Executable

build_exe_options = {"includes" : ["re"], "include_files" : ["data/table_1.txt", "data/table_2.txt"]}

setup(name = "My Script",
      version = "0.8",
      description = "My Script",
      options = { "build_exe" : build_exe_options },
      executables = [Executable("my_script.py")])

fileutil.py （尝试读取资源文件的地方）

def read_file(filename):
    path, fl = os.path.split(os.path.realpath(__file__))
    filename = os.path.join(path, filename)
    with open(filename, "r") as file:
        lines = [line.strip() for line in file]
        return [line for line in lines if len(line) == 0 or line[0] != "#"]

......跟......打电话。

read_file("data/table_1.txt")

以下结构对我有用：

|-main.py
|-src
 |-utils.py (containing get_base_dir())
|-data

然后引用你的数据总是相对于你通过src目录中的以下函数收到的main.py的位置：

import os, sys, inspect
def get_base_dir():
   if getattr(sys,"frozen",False):
       # If this is running in the context of a frozen (executable) file, 
       # we return the path of the main application executable
       return os.path.dirname(os.path.abspath(sys.executable))
   else:
       # If we are running in script or debug mode, we need 
       # to inspect the currently executing frame. This enable us to always
       # derive the directory of main.py no matter from where this function
       # is being called
       thisdir = os.path.dirname(inspect.getfile(inspect.currentframe()))
       return os.path.abspath(os.path.join(thisdir, os.pardir))

如果您根据cx_Freeze文档包含数据，它将与.exe文件位于同一目录中（即不在zip文件中），这将与此解决方案一起使用。

如何使用cxfreeze适当地包含外部资源？
