我正在尝试创建一个具有诸如requests之类的依赖项的简单项目，并使用以下命令创建一个分布式zip文件：python3.6 setup.py bdist --format=zip。在dist zip文件中，还应该使用以下bash脚本创建package.zip：
#!/bin/bash
pip install -r requirements.txt --target ./packages
if [[ -d packages ]]; then
cd packages
find . -name "*.pyc" -delete
find . -name "*.egg-info" | xargs rm -rf
zip -9mrv packages.zip .
mv packages.zip ..
cd ..
rm -rf packages
fi
最终的zip文件包含以下文件：
Archive: dist/test_python_zip-1.0.linux-x86_64.zip

setup.py文件的内容为：

最后，主要 .py文件的内容为：
import sys
if not ('packages.zip' in sys.path):
sys.path.insert(0, 'packages.zip')
print(sys.version)
print("\n \n")
print(sys.path)
from src.commands import hello
def main():
hello.call()
if __name__ == '__main__':
main()
这里的问题是没有从package.zip文件中加载requirements依赖项，如果未安装，则出现以下错误：
3.7.3 (default, Apr 3 2019, 05:39:12)

ModuleNotFoundError: No module named 'requests'
应该是什么问题，我该如何解决？
答案 0 :(得分：0)
我没有在最终的zip中使用 package.zip ，而是使用了 package 文件夹，该文件夹移至 src 软件包下。我在内容中添加了 MANIFEST.in
include packages __main__.py
recursive-include src/commands *
setup.py更改为
from distutils.command.bdist_dumb import bdist_dumb
from distutils.core import setup
from setuptools import find_packages
class CustomBdistDumb(bdist_dumb):
def reinitialize_command(self, name, **kw):
cmd = bdist_dumb.reinitialize_command(self, name, **kw)
if name == 'install':
cmd.install_lib = '/'
return cmd
setup(
# our custom class override
cmdclass={'bdist_dumb': CustomBdistDumb},
name='test_python_zip',
version="1.0",
package_data={
'': ['packages']
},
py_modules=['__main__'],
packages=find_packages(),
)
和 request 模块直接从 packages 文件夹中加载：
from src.packages import requests
URL = "https://api.ipify.org/?format=json"
def call():
# sending get request and saving the response as response object
r = requests.get(url=URL)
# extracting data in json format
data = r.json()
print(data)
