使用 cx_Freeze 使 grpc python 代码执行：没有名为 'pkg_resources' 的模块

Question

我正在用 python 制作 grpc 服务器。我的目标是使用 cx_Freeze.

构建一个可执行文件

在我使用cx_Freeze制作greeter_server.exe之后，当我运行greeter_server.exe时，我遇到了这个错误。

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是这样的

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")],
)

我试了很多次。

pip 安装 grp pip 安装 grpcio pip 安装 grpcio-tools

pip install --upgrade setuptools pip install --upgrade distribute

但是当我尝试 pip install —upgrade distribute 时遇到这个错误。

    ----------------------------------------

我使用的是 Anaconda3-5.2.0，Python3.6.7。（因为我要用tensorflow）

任何帮助将不胜感激。

Answer 1

像下面那样编辑 setup.py 文件后，它起作用了。

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

Answer 2

pkg_resources 需要添加到 build_exe 选项的 packages 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正常工作（这些条目可在 OP 自己的答案中找到，但在问题的设置脚本中缺失）。

使用 cx_Freeze 使 grpc python 代码执行：没有名为 'pkg_resources' 的模块

make grpc python code to exe with cx_Freeze : No module named 'pkg_resources'

python

pyinstaller

cx-freeze

python-3.x
