Question

我正在尝试在Alpine docker image（3.9）上启动一个简单的uWSGI服务器。这是Python脚本

import hashlib
import os
from urllib.parse import urlparse
import zipfile
import tempfile
import subprocess
from pathlib import Path

import pandas as pd
import requests

DATA_DIR = Path(save_cache_path('yourdatadirname'))
if not DATA_DIR.exists():
    os.mkdir(DATA_DIR)
def hash(s):
    try:
        return hashlib.sha256(s).hexdigest()
    except TypeError:
        return hashlib.sha256(s.encode('utf-8')).hexdigest()

def delete_cached_file(url):
    '''
    Helper function to delete an erroneous file or something like that..
    '''
    filename = DATA_DIR / hash(url)

    os.remove(filename)


def ssh_file(url):
    filename = DATA_DIR / hash(url)

    if not filename.exists():
        subprocess.run(['scp', url, filename])

    return filename


def http_file(url, zip_extract_name=None):
    '''
    Automatically downloads a URL (if not cached) and provides the file path;
    Also tries to automatically unzip files (only works with ZIP files containing a single file with the correct naming..)
    :zip_extract_name: extract the specified filename from a ZIP file
    '''
    filename = DATA_DIR / hash(url)

    if not filename.exists():
        r = requests.get(url, allow_redirects=True)

        url_filename = os.path.basename(urlparse(url).path)
        inner_url_filename, ext = os.path.splitext(filename)
        if zip_extract_name:
        # if ext == '.zip':
            zf = tempfile.NamedTemporaryFile(delete=False)
            zf.write(r.content)
            zf.close()

            with zipfile.ZipFile(zf.name, 'r') as zipped_file:
                data = zipped_file.read(zip_extract_name)
        else:
            data = r.content
        with open(filename, 'wb') as f:
            f.write(data)

    return filename

我正在尝试使用以下命令启动它：

def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"]

但是，每次尝试此操作都会出现此错误：

uwsgi --plugins http,python3,gevent --http :8081 --uid nobody --gid nobody --wsgi-file hello.py --module hello --master --processes 4 --gevent 2 --gevent-monkey-patch --socket /tmp/uswgi.sock

我尝试安装!!! UNABLE to load uWSGI plugin: Error relocating /usr/lib/uwsgi/gevent_plugin.so: PyInt_FromLong: symbol not found !!! uwsgi: unrecognized option: gevent getopt_long() error软件包，但是命令仍然失败。有谁知道为什么会这样？这是我的Dockerfile：

python3-dev

RUN apk add --no-cache --update \ python3 \ python3-dev \ py3-gevent \ uwsgi \ uwsgi-python3 \ uwsgi-http \ uwsgi-gevent3是Python 2 uWSGI插件：
https://pkgs.alpinelinux.org/package/v3.9/main/x86_64/uwsgi-gevent

对于Python 3，您需要uwsgi-gevent3。

此外，您缺少gevent Python模块的py3-gevent软件包。

总而言之，更新的软件包列表：

gevent3

此外，别忘了使用gevent插件代替uwsgi --plugins http,python3,gevent3：

puma.rb

gevent uwsgi插件未在Alpine docker中加载
