有两天我一直在努力安装pyzmq,我真的不确定是什么问题.

我之后收到的错误消息:

pip install pyzmq

是:

 error: command 'gcc' failed with exit status 1

我安装了gcc.

which gcc
/usr/bin/gcc

Python安装在同一位置.我真的很难找到解决方案.

编辑:添加到错误的输出,这是进一步描述错误的输出:

 bundled/zeromq/src/signaler.cpp:62:25: fatal error: sys/eventfd.h: No  such file or directory
  #include <sys/eventfd.h>
                         ^
compilation terminated.
error: command 'gcc' failed with exit status 1

----------------------------------------
Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip- build-INbMj2/pyzmq/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), 
__file__, 'exec'))" install --record /tmp/pip-n8hQ_h-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-INbMj2/pyzmq

编辑二:遵循https://github.com/zeromq/pyzmq/issues/391的安装说明

pip install pyzmq --install-option="fetch_libzmq"

收益率:

#include <sys/eventfd.h>
                         ^
compilation terminated. …

我有兴趣看看Requests是否可以处理我在Mechanize中主要做的一些任务.

Mechanize可以轻松处理填写表单和提交表单,我很难在Requests中尝试做同样的事情.

例如,

import mechanize
br = mechanize.Browser()
url = "https://www.euronext.com/en/data/download?ml=nyx_pd_stocks&cmd=default&formKey=nyx_pd_filter_values%3A18d1ee939a63d459d9a2a3b07b8837a7"
br.open(url)
br.select_form(nr=1)
br.form['format']=['2']
br.form['date_format']=['2']
response = br.submit().read()

请求是否等同于:

import requests
url = "https://www.euronext.com/en/data/download?ml=nyx_pd_stocks&cmd=default&formKey=nyx_pd_filter_values%3A18d1ee939a63d459d9a2a3b07b8837a7"
payload = {'format':'2','date_format':'2'}
r = requests.post(url, data=payload)

requests.post是否提交表格以下载页面上嵌入的CSV？

此外,有关其他信息,以下是页面上的表单:

for form in br.forms():
    print form
