Question

我正在用python制造grpc服务器。我的目标是使用cx_Freeze构建可执行文件。

使用cx_Freeze创建greeter_server.exe后，运行greeter_server.exe时遇到此错误。

Traceback (most recent call last):  
File “greeter_server.py", line 19, in <module>   
File “c:\users\User\anaconda3\envs\tensorflow\lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 627, in exec_module     exec(bytecode, module.__dict__)   
File “site-packages\grpc\__init__.py", line 22, in <module>  
File “src\python\grpcio\grpc\_cython\cygrpc.pyx", line 18, in init grpc._cython.cygrpc 
ModuleNotFoundError: No module named ‘pkg_resources'

我的setup.py就是这样。

import sys
from cx_Freeze import setup, Executable

build_exe_options = {}

setup(
    name='py freeze test',
    version='0.0.1',
    description="greeter_server function test",
    author="ray",
    options={'build_exe':build_exe_options},
    executables=[Executable("greeter_server.py")],
)

我尝试了很多次。

pip install grp 点安装grpcio pip安装grpcio-tools

pip install --upgrade setuptools pip install --upgrade分发

但是当我尝试点安装-升级分发时，遇到此错误。

我正在使用Anaconda3-5.2.0，Python 3.6.7。（因为我必须使用张量流）

任何帮助将不胜感激。

Answer 1

像下面这样编辑setup.py文件后，它可以工作。

build_exe_options = {
    'packages':['grpc','pkg_resources', 'numpy', 'tensorflow'],
}

Answer 2

pkg_resources需要添加到packages选项的build_exe列表中：

build_exe_options = {'packages': ['pkg_resources']}

备注：packages列表中可能需要其他条目才能使设置脚本起作用（这些条目在OP自己的答案中找到，但在问题的设置脚本中找不到）。

使用cx_Freeze使grpc python代码成为exe文件：没有名为“ pkg_resources”的模块
