Python 3: How to Solve Demjson Install Error

The following error occurs when Python 3 installs demjson 2.2.4

error in demjson setup command: use_2to3 is invalid

Since demjson 2.2.4 is compatible with python2 and python3, some code needs to be converted when the installation environment is python3

Setuptools no longer supports 2to3 builds from version 58.0.0, so demjson 2.2.4 is no longer available after installation,

It can be solved by demoting the version of setuptools

pip install --upgrade setuptools==57.5.0

[Solved] Python 3 installation pilot error: Building wheel for pillow (setup.py) … error

Foreword

Recently, the pilot library will be used to train the verification code model, but it can’t be installed alive or dead

Environment

Installed in docker, python3

Try to install

pip install pillow

easy_install Pillow

pipenv install pillow

As a result, life and death just can’t fit it

Errors are reported as follows:

Solving

I searched hard on the Internet and finally found the answer in stack overflow. It turned out that there was a lack of dependency package

https://stackoverflow.com/questions/44043906/the-headers-or-library-files-could-not-be-found-for-jpeg-installing-pillow-on/44044479#44044479

Solution

In build Add the following contents to the dockerfile file:

FROM python:alpine
RUN apk --update add libxml2-dev libxslt-dev libffi-dev gcc musl-dev libgcc openssl-dev curl
RUN apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev
RUN pip install Pillow

So you can build successfully

You can enter the container

Install these dependencies directly, and then you can install them directly in the container without rebuilding the image

apk add jpeg-dev zlib-dev freetype-dev lcms2-dev openjpeg-dev tiff-dev tk-dev tcl-dev

Supplement

Well, you can use it happily. Others may be permission errors, or switch to the installation source

python3 can’t concat str to bytes

Byte type cannot be “+” with string directly. Use str() to convert byte type part into string

Python3 Use urlliburlopen error EOF occurred in violation of protocol (_ssl.c:841)

python3:

import urllib.request
from bs4 import BeautifulSoup

response = urllib.request.urlopen("http://php.net/")
html = response.read()
soup=BeautifulSoup(html, "html5lib")
text=soup.get_text(strip=True)
print(text)

The code is very simple, just grabbing http://php.net/ Page text content, and then use the beautifulsoup module to clear and filter out redundant HTML tags. It seems that the permission was successful for the first time, and then stuck all the time and reported an error again:

File "C:\Python36\lib\urllib\request.py", line 504, in _call_chain
    result = func(*args)
  File "C:\Python36\lib\urllib\request.py", line 1361, in https_open
    context=self._context, check_hostname=self._check_hostname)
  File "C:\Python36\lib\urllib\request.py", line 1320, in do_open
    raise URLError(err)
urllib.error.URLError: <urlopen error EOF occurred in violation of protocol (_ssl.c:841)>

In fact, Google browser is accessible

This problem may be due to the fact that sslv2 is disabled on the web server, and the older Python library Python 2. X tries to work with protocol by default_ Sslv23 establishes the connection. Therefore, in this case, you need to select the SSL version that you want to use

To change the SSL version used in HTTPS, you need to subclass the httpadapter class and mount it to the session object. For example, if you want to force the use of tlsv1, the new transport adapter will look like this:

from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager

class MyAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                       maxsize=maxsize,
                                       block=block,
                                       ssl_version=ssl.PROTOCOL_TLSv1)

Then, you can mount it to the requests session object:

s=requests.Session()
s.mount('https://', MyAdapter())
response = urllib.request.urlopen("http://php.net/")

It’s easy to write a universal transport adapter, which can get any SSL type from the package in the SSL constructor and use it

from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager

class SSLAdapter(HTTPAdapter):
    '''An HTTPS Transport Adapter that uses an arbitrary SSL version.'''
    def __init__(self, ssl_version=None, **kwargs):
        self.ssl_version = ssl_version

        super(SSLAdapter, self).__init__(**kwargs)

    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                       maxsize=maxsize,
                                       block=block,
                                       ssl_version=self.ssl_version)

The above error code after modification:

import urllib.request
from bs4 import BeautifulSoup
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager
import ssl

class MyAdapter(HTTPAdapter):
    def init_poolmanager(self, connections, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connections,
                                       maxsize=maxsize,
                                       block=block,
                                       ssl_version=ssl.PROTOCOL_TLSv1)

s=requests.Session()
s.mount('https://', MyAdapter())
response = urllib.request.urlopen("http://php.net/")
html = response.read()
soup=BeautifulSoup(html, "html5lib")
text=soup.get_text(strip=True)
print(text)

It can capture web page text information normally

Unable to return file stream in Python 3, uwsgi report error

Why can’t you stop buying 618?From the technical dimension to explore>>>

Questions

In the python 3 environment, when the web returns a file stream (for example, Django returns fileresponse), it will find that the client has not received any return, and the download will prompt a network error

Check the uwsgi log and find that the error is as follows:

io.UnsupportedOperation: fileno

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/django/core/handlers/wsgi.py", line 156, in __call__
    response = environ['wsgi.file_wrapper'](response.file_to_stream)
SystemError: <built-in function uwsgi_sendfile> returned a result with an error set

Solution

Method 1

Add the -- WSGI disable file wrapper = true option to the uwsgi startup configuration, and then restart

https://github.com/unbit/uwsgi/issues/1126

https://uwsgi-docs.readthedocs.io/en/latest/Changelog-2.0.12.html#wsgi -disable-file-wrapper

Method 2

Use other ways to download, such as uploading to alicloud, qiniu, etc., and return to the download address to download

Python3 AttributeError: module ‘sys’ has no attribute ‘setdefaultencoding’

  reload(sys)
    sys.setdefaultencoding("utf-8")
    f = open('.\\24.novel.txt','rb')
    str = f.read().decode('utf-8')
    f.close()

Found by Baidu

Python 3 string encodes Unicode by default, so sys. Set default encoding doesn't exist

So just delete it

Using pyenv causes the problem that python3 cannot import SQLite3

Geeks, please accept the hero post of 2021 Microsoft x Intel hacking contest>>>

Questions

I want to install a jupyter to use the functions of notebook. However, when I execute jupyter notebook , I report an error directly

ModuleNotFoundError: No module named '_sqlite3'

Strange, isn’t python3 supported by SQLite3?Solution

Looking at the mistakes, I remember that my Linux version of Python is managed by pyenv, so now 3.7.4 is actually installed by pyenv install 3.7.4 . Pyenv installation, in fact, is to download the source code from the official website to compile and install, so think of it, is it difficult because the SQLite3 development package is not installed

Try to execute sudo apt install libsqlite3 dev , and it is not installed

After the installation is completed, you can go over pyenv install 3.7.4 , ask if you want to re install it, then download the source code from the official website and compile it. It takes about 10 minutes to compile, execute Import SQLite3 , and it’s OK

Postscript

It seems that pyenv also has trouble managing python. After that, I don’t know how many functions are available because it doesn’t have any dependencies installed, so it doesn’t turn on this feature directly

How to use htmltestrunner.py to report importerror: no module named ‘stringio’ in Python 3

How to use htmltestrunner.py to report importerror: no module named ‘stringio’ in python3

1. The reason is that the official website is written in python2 syntax, and the official manually changes the official website’s htmltestrunner.py to python3 syntax:

2. Modification summary:

There is a problem with the file opening method. If you change the previous opening statement to binary mode, there is no problem
