Python 如何在cxfreeze中适当地包含外部资源?
我正在尝试使用将Python脚本构建到Python 如何在cxfreeze中适当地包含外部资源?,python,python-3.x,cx-freeze,Python,Python 3.x,Cx Freeze,我正在尝试使用将Python脚本构建到.exe文件中。但是,我的脚本使用一些外部数据文件,这些文件没有打包到创建的libary.zip文件中 例如,我的脚本位于src/中,外部数据位于src/data/中。我在build_exe_options中指定了include_files属性,但这只会将目录和文件复制到build目录中;它不会将它们添加到library.zip,脚本最终会在那里查找文件 即使我进入创建的library.zip并手动添加数据目录,我也会收到相同的错误。你知道如何让cxfree

对这些外部资源进行适当的打包吗
setup.py

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位置)
。。。打电话给
read_file("data/table_1.txt")

FileNotFoundError:[Errno 2]没有这样的文件或目录:

以下结构适合我:
|-main.py
|-src
|-utils.py (containing get_base_dir())
|-data
然后,在src目录中通过以下函数接收main.py位置相关的数据:
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zipfile中),该文件将用于此解决方案。以下是文档的相关位:
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))
