Collection and solution of error reporting in pyspider

Command “python setup.py egg_ info” failed with error code 10

This means that pycurl installation reported an error

Download address of WHL file of pycurl in win10 solution

# Follow the link above to download the pycurl whl file, pay attention to your own python version, I'm using python 3.7 here
# locate the path to change the file
pip3 install pycurl-7.43.0.4-cp37-cp37m-win_amd64.whl

CentOS solution

yum install python-devel curl-devel
pip3 install pycurl

Ubuntu solution

sudo apt-get install libcurl4-gnutls-dev
pip install pyspider

SyntaxError: invalid syntax

Async cannot be used as a keyword and needs to be changed as a variable

Run pyspider to find the error file and replace async to know that the error was not reported

[Python] pip.vendor.urllib3.exceptions.readtimeouterror: httpsconnectionpool protocol

When installing a python module with pip or pychar, you sometimes encounter a readtimeout error. The reason for this problem is probably the network speed

my default source is Tsinghua, sometimes the link network is not good ( the day after the college entrance examination today, it is estimated that there are too many visitors, everyone wants to go to Tsinghua, ha ha ), so I change the source.

pip --default-timeout=100 install pyspark -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com

Perfect solution

Processing method of PIP exception no module named ‘pip’

1、 Pip is not installed
most of the current versions of python (2.7.9 + or 3.4 +) come with PIP. You can use the following command first:
PIP -- version (Python 2. + version)
PIP3 -- version (Python 3. + version)
try to check the version of PIP. If it can be displayed normally, PIP should have been installed.

If pip is not installed, the official download address of PIP is:
0 https://pypi.org/project/pip/

Installation:
Step 1: decompress
Step 2: open the console at the decompressed position
Step 3: use the command Python setup.py install
Step 4: check whether the PIP is installed again, if not, restart the computer

2、 The missing environment variable
may be that the option of add path was not checked when installing python, and the path of Python and pip.exe needs to be added to the environment variable manually
e.g:
C:\Users\Example\AppData\Local\Programs\Python\Python39-32;

and
C: users, example, appdata, local programs, python, python39-32, scripts Python comes with PIP, but when it is used to install packages, it will still report “no mouse named ‘pip'”<
use the command:
Python - M ensurepip

after the installation, PIP can be used normally.

Python PIP Fatal error in launcher: Unable to create process using ‘“e:\program files\programdata

Error content

Fatal error in launcher: Unable to create process using '"e:\program 
files\programdata\python3.9\python.exe"  "E:\Program Files\ProgramData
\Python39\Scripts\pip.exe" ': ???????????

Solution

python -m pip install --upgrade pip

Problem solving
there is a problem with PIP. Updating PIP through Python will delete the wrong PIP and install the updated pip

The solution of no module named ‘jinja2. Asyncsupport’

Background of the problem

When compiling Px4,

make px4_sitl_default gazebo

An error has been reported,

The resulting version is 2.10.
Obviously, jinja2 was not installed in the path we needed.

2. Check the location of jinja2 in the current path, and find the cause of the problem

>>> exit()

After coming to the directory ‘/ usr / lib / python2.7/dist-packages/jinja2’, I found that there are no files in the directory asyncsupport.py . The PY file is missing from the official website.

3. Delete jinja2 from the specified directory and install a new jinja2

Unload command:

sudo  rm -r /usr/lib/python2.7/dist-packages/jinja2

Output results:

Solution of error reporting in PIP installation of iPhone

Today, I encountered a problem when configuring pycaffe environment. I need to execute it when installing the library

for req in $(cat requirements.txt); do pip install $req; done
sudo pip install -r requirements.txt

Command, always report red error. Finally, sort it out.

First, there are various kinds of permission denied, which are finally solved by the root account operation.
Next, after all the others are installed, it’s hard to install IPython. You can install it with PIP install IPython
alone, and the error is:
command "Python" setup.py egg_ Info "failed with error code 1 in/TMP/pip-build-a63c8f/IPython/
after searching, we find the reason: the default version of IPython is too high, so we can only reduce the version manually.

pip install ipython==8888

The above command entered a non-existent version, so that all existing versions will be listed in the prompt.

After trying, the 6 and above versions all report errors, and finally use the highest version of 5.

sudo pip install ipython==5.5.0

Execute sudo PIP install - R again requirements.txt , there is a piece of requirement already satisfied . It's done!

ps:

    for reference only: my PIP version is manually upgraded to 9.0.2, and the python version comes with 2.7; warm tips: try to use root user to operate the whole process, not sudo, which can save a lot of trouble.

Could not install packages due to anenvironment error: [winerror 5] access denied

I’ve been learning Python before, but I’m not familiar with PIP

Every time you install a package, PIP will

You are asked to install the updated version of PIP, which is 10.1

But after the update, when installing other libraries, we habitually install the libraries in the same way as before

This is a problem

Due to time constraints, pip10.1 has no time to study. I want to go back, but I can’t

Look at the wrong requirements

Just Python – M PIP install — user — upgrade PIP = = 9.0.3

Just add a — user

As for why, I don’t know. I’ll be in a hurry when I have a problem. I can use it

If you still report an error when installing some packages after returning!!

I often encounter this error, and I feel that the online solutions are a bit messy

Just add a — user directly after install

To solve Anaconda error: command error out with exit status 1

1. PIP error: cannot open D: anaconda3/scripts/pip- script.py

2. PIP switches domestic sources

3. Solve SciPy error: importerror: cannot import name ‘show_ config’ from ‘numpy’ (unknown location） 

4. Solve the problem of error: command error out with exit status 1

5. After installing scikit learn, it can be imported, but the running error is: importerror: DLL load failed: the specified program cannot be found

 

—————————————————————————————————————————————————————-

 

This error is due to the dependency package version is too high (too new).

Phenomenon restore: install scikit learn with anaconda, and then install Matplotlib to report the above error.

Solution: the installed version of Matplotlib is too high, and it can be solved by reducing the version.

 

 

However, this is not the end. Generally, scikit learn installed with the CONDA command may import normally, but it is easy to report an error when using it

The solution is to uninstall sklearn, and then use pip to install it again. However, if you directly use the PIP install scikit learn command to install it, there may be errors, and the process of installing again will be very complicated

See:

After installing sklearn, it can be imported normally, but an error is reported

 

Welcome to my personal blog: the road of machine learning

 

PIP installation error: Microsoft Visual C + + 14.0 is required perfect solution

In the process of using Python development, we often need to install various modules, but we often encounter various errors in the installation process, such as: error: Microsoft Visual C + + 14.0 is required, this error is due to the lack of C + + compiler components.

There are two solutions to this problem

One is to directly download the corresponding wheel file for installation, providing three download addresses:

Tsinghua download (domestic site, fast speed) https://pypi.tuna.tsinghua.edu.cn/simple/pip/

Official download: https://pypi.org/project/face-recognition/1.0.0/#files

Python package https://www.lfd.uci.edu/~gohlke/pythonlibs/

Another solution is to install the missing components.

As for the second solution, I believe most people will download a visual studio 201x and install it as I used to. However, installing a vs takes up a lot of space, not to mention the key. Some people find it useless after installation, which is really irritating.

After all kinds of search, it was found that the C + + runtime provided by the government can be directly installed, which can be solved perfectly. The address is Microsoft Visual C + + build tools 2015

 

After downloading, double-click run to install with default settings. After the installation, go to PIP install XXX to show that the installation is successful.

 

Welcome to my personal blog: the road of machine learning

Error from Python installation Library: Microsoft Visual C + + 14.0 is required

Error: Microsoft Visual C + + 14.0 is required. Get it with Microsoft Visual C + +

Error: Microsoft Visual C + + 14.0 is required. Get it with “build tools for visual studio”: https://visualstudio.microsoft.com/downloads/

Finally, a Microsoft Visual C + + build tools 2015
is found https://go.microsoft.com/fwlink/?LinkId=691126
The file name is: visual cppbuildtools full, download and install.

Double click visual cppbuilder tools_ full.exe , select the default, click Install, and wait about 10 minutes to complete the installation.
Then install the PIP library.

The scheme failed with ‘command’ failed
