i had a problem with installing packages to new upgraded python to version 3.7
When i type:
python3.7 -m pip install pip -d
/usr/local/bin/python3.7: No module named pip
I make easy_install like this: sudo easy_install pip what solve previous problems, but now it create pip3.7 in a weird way. Whem i calling for pip3.8 version, this returns me a message:
pip3.7 -V
pip 19.2.3 from /usr/local/lib/python3.5/dist-packages/pip (python 3.5)
Someone know what i am doing wrong? I tried many things to resolve it. Reinstall, purge, install with symbolic link from python2 etc.
There is a script which i used to install python3.7 (i had also a problem with zlib):
sudo cd /home
sudo wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
sudo tar xf Python-3.7.3.tar.xz
sudo cd ./Python-3.7.3/
sudo ./configure
sudo make
sudo make install
sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3 10
python3 --version
Where is a mistake?
Answer finally i find myself. There: https://linuxize.com/post/how-to-install-python-3-7-on-debian-9/
There with similar errors you can recompile it, even without removal (on secound machine i checked without removal) failed installation before.
If someone want to good upgrade with everywith working on debian 9. I recommend that script:
NOW_DIR=$(pwd)
apt update
apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget
mkdir ~/python_upgrade
cd ~/python_upgrade
curl -O https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
tar -xf Python-3.7.3.tar.xz
cd Python-3.7.3
./configure --enable-optimizations
make -j $(nproc)
make altinstall
python3.7 --version
cd $NOW_DIR
rm -rf ~/python_upgrade
There are minor changes from that commands in tutorial. Run above file.sh as root.
It can take some times, on my virtual machine with 2 cores during another job it takes 40 minutes. I hope someone find there good answer, not totally green comments like 'apt install' which is first try action before looking to web.

I need python newest version in raspberry pi.
I tried apt install python3 3.8 apt install python3 but this didnot work.
And I also needed to update my raspberry pi python IDLE
First update the Raspbian.
sudo apt-get update
Then install the prerequisites that will make any further installation of Python and/or packages much smoother.
sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev
And then install Python, maybe by downloading a compressed file?
example 1 :
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
Extract the folder :
sudo tar zxf Python-3.8.0.tgz
Move into the folder :
cd Python-3.8.0
Initial configuration :
sudo ./configure --enable-optimizations
Run the makefile inside the folder with the mentioned parameters :
sudo make -j 4
Run again the makefile this time installing directly the package :
sudo make altinstall
Maybe You already did it but You don't know how to setup the new version as a default version of the system?
Check first that it has been installed :
python3.8 -V
Send a strong command to .bashrc telling him who (which version) is in charge of Python
echo "alias python=/usr/local/bin/python3.8" >> ~/.bashrc
Again! Tell him because .bashrc has to understand! I am joking - You have to source the file so the changes can be applied immediately :
source ~/.bashrc
And then check that Your system changed the default version of Python to Python 3.8
python -V
The failure depends on many factors : what dependencies are installed, what are the packages added to the source_list.d, some inconvenient coming up during the installation. All may give you more information than you think, just read carefully.
Hope it helped.
To all of you who got problem with freezing RPi 3 in step:
sudo make -j 4
just change it to:
sudo make -j 2
or simply:
sudo make
Best regards
Follow below commands to install the version which you want:
tar xf Python-3.x.x.tar.xz
cd Python-3.x.x
./configure --enable-optimizations
make
sudo make install
once completed run python -V
Since I found no answer for my question, neither in older posts nor in other forums, I want to ask the stackoverflow community for advice.
I am using a raspberry pi 3B+, version 9.4 (lite) with kernel version 4.14.71-v7.
I use python3.6. I installed it as follows:
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
cd /usr/src
sudo wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
sudo tar xzf Python-3.6.0.tgz
sudo -s
cd Python-3.6.0
bash configure
make altinstall
exit
Installation was without any trouble and everything works perfectly.
Now I wanted to install the PyQt5 modul for python3.6. I usually use
sudo python3.6 -m pip install ...
for installing a modul for python3.6. Trying
sudo python3.6 -m pip install pyqt5
gave me the error message
Could not find a version that satisfies the requirement PyQt5 (from versions: )
No matching distribution found for PyQt5
So I tried
sudo apt-get update
sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools
But it installed PyQt5 for python3.5 (which is preinstalled) on the raspberry.
So does anybody know how to use or install PyQt5 for the subsequently installed
python3.6?
Edit 08.03.2019:
Thanks FlyingTeller. I started to build from source. I followed the steps from
your link.
sudo apt-get update
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo -s
python3.6 configure.py --sip-module=PyQt5.sip
make
make install
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
python3.6 configure.py
Then I received the following error
Error: Use the --qmake argument to explicitly specify a working Qt qmake.
I think I am on the right way, but I do not understand what qmake is or what it
means.
Edit 10.03.2019:
I could solve the last error message. I installed
sudo apt-get install qt5-default
Then I did the same procedure as already mentioned. Now I get the error
fatal error: sip.h: File or directory not found
#include <sip.h>
PyQt5 config.py is in: /usr/src/PyQt5_gpl-5.12
SIP sip.h is in: /usr/src/sip-4.19.14
Anybody an idea? Thanks guys.
Today I found the solution. The steps below worked for me, without any error. The whole process took almost two hours.
sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install sip-dev
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo python3.6 configure.py --sip-module PyQt5.sip
sudo make
sudo make install
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
sudo python3.6 configure.py
sudo make
sudo make install
Seems like they moved some things around. This seems to work, as far as getting things, and compiling them. It takes a long time to build.
For the associated designer, look at:
QtDesigner for Raspberry Pi
sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install sip-dev
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/4.19.23/sip-4.19.23.tar.gz
sudo tar xzf sip-4.19.23.tar.gz
cd sip-4.19.23
sudo python3 configure.py --sip-module PyQt5.sip
sudo make
sudo make install
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/5.13.2/PyQt5-5.13.2.tar.gz
sudo tar xzf PyQt5-5.13.2.tar.gz
cd PyQt5-5.13.2
sudo python3 configure.py
sudo make
sudo make install
In my case it helped to update pip from verion 18 to the newest, in my case 20.2 (python -m pip install --upgrade pip) and then do a pip install PyQt5.
The instructions used in the accepted answer did not work for me. I think it's simply because they are outdated. I wanted to post the list of commands that did work for me. I'm running a Pi 400 with the latest version of Raspbian as of 12/20/2020. I used the default python3 rather than python3.6.
Here is the modified list of commands that worked for me:
sudo apt-get install qt5-default
sudo apt-get install sip-dev
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-5.5.1.dev2011271026.tar.gz
sudo tar xzf sip-5.5.1.dev2011271026.tar.gz
cd sip-5.5.1.dev2011271026
sudo python3 setup.py build
sudo python3 setup.py install
sudo wget https://files.pythonhosted.org/packages/28/6c/640e3f5c734c296a7193079a86842a789edb7988dca39eab44579088a1d1/PyQt5-5.15.2.tar.gz
sudo tar xzf PyQt5-5.15.2.tar.gz
cd PyQt5-5.15.2
sudo python3 configure.py
sudo make
sudo make install
Can't comment due to reputation but I would add to Christ Troutner's useful updated answer, that in case users get a No module named 'PyQt5.sip' error, try --sip-module PyQt5.sip during configure, per the docs:
Note
When building PyQt5 v5.11 or later you must configure SIP to create a
private copy of the sip module using a command line similar to the
following:
python configure.py --sip-module PyQt5.sip
If you already have SIP installed and you just want to build and
install the private copy of the module then add the --no-tools option.
The accepted answers did not work for me, below is the code that worked for me.
sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install qtcreator
This code not only installs Qtcreator but also installs Qt5 Assistant, Qt5 Designer, and Qt5 Linguist
I'm trying to install apache-airflow the recommended way with pip install apache-airflow. During the install of pendulum (a dependency), I get an error:
error: can't copy 'pendulum/parsing': doesn't exist or not a regular file
I think it's related to Python distutils error: "[directory]... doesn't exist or not a regular file", but that doesn't give an answer as to how one resolves this when using pip. Pulling the tar for pendulum and installing using python setup.py install works, but then when subsequently I do pip install apache-airflow again, it sees that pendulum is already installed, UNINSTALLS, and then tries to install again using pip, resulting in the same error. I'm using a docker container and installing python-setuptools with apt-get before I do any of this. Here's my dockerfile, fwiw...
FROM phusion/baseimage:0.10.1
MAINTAINER a curious dev
RUN apt-get update && apt-get install -y python-setuptools python-pip python-dev libffi-dev libssl-dev zip wget
ENV SLUGIFY_USES_TEXT_UNIDECODE=yes

RUN tar -xzvf pendulum-2.0.4.tar.gz
RUN cd pendulum-2.0.4/ && python setup.py install
RUN pip install apache-airflow
CMD airflow initdb && airflow webserver -p 8080
Does anyone see anything I'm doing wrong? I haven't found anyone else with this error so I think there's something really obvious I'm missing. Thanks for reading.
Upgrade pip first.

I wanna set up scrapy cluster follow this link scrapy-cluster,Everything is ok before I run this command:
pip install -r requirements.txt
The requirements.txt looks like:
cffi==1.2.1
characteristic==14.3.0
ConcurrentLogHandler>=0.9.1
cryptography==0.9.1
...
I guess the above command means to install packages in requirements.txt.But I don't want it to specify the version,So I change it to this:
cat requirements.txt | while read line; do pip install ${line%%[>=]*} --user;done
When install cryptography,it gives me the error:
build/temp.linux-x86_64-2.7/_openssl.c:12:24:fatal error:pyconfig.h:No such file or directory
#include <pyconfig.h>
I don't know how to solved this , I have tried a lot of methods ,but failed. my system is centos 7, and the version of python is 2.7.5(default).
Besides, Is there any other scrapy frame which is appliable for a large number of urls . Thanks in advance
For Ubuntu, python2
apt-get install python-dev
For Ubuntu, python3
apt-get install python3-dev
I have solved it by myself. for the default python of centos, there is only a file named pyconfg-64.h in usr/include/python2.7/,So run the command
yum install python-devel
Then it works.
for python3.6,
apt-get install python3.6-dev
and
apt-get install libssl-dev libffi-dev
i use python 2 on ubuntu and got the same problem when installing cryptography.
after i run this command
apt-get install python-dev libssl-dev libffi-dev
then it works.
For Python 3.7 on Debian, the following works for me.
apt-get install python3.7-dev
and
apt-get install libssl-dev
You may also need:
apt-get install libffi-dev
On a Debian based distro (AntiX distro), together with apt-get install python3-dev, I also installed rust, to complete successfully the pip3 install cryptography command. So, I gave:
$ sudo apt-get install build-essential curl python3-dev libssl-dev libffi-dev
$ sudo curl https://sh.rustup.rs -sSf | sh
When prompted (Figure 1), type 1 and hit Enter on your keyboard.
Once it completes, you have to give following commands:
$ source $HOME/.cargo/env
$ source ~/.profile
$ pip3 install cryptography
I got no-site-packages error while trying to install hue on my local system. Is there anyone who knows how to solve such an issue?
This is the commands I ran:
$ git clone git#github.com:cloudera/hue.git
$ sudo apt-get install (the ap list shows in https://github.com/cloudera/hue)
Enter Hue
$ make apps
I tried the solution which is provided in Google groups, but the same issue still keeps showing up:
$ sudo apt-get install python-pip
$ sudo pip install --upgrade virtualenv
$ cd /usr/lib/python2.7
$ sudo ln -s plat-x86_64-linux-gnu/_sysconfigdata_nd.py
Any help will be appreciated!
Weird, this seems to be the exact same problem as https://issues.cloudera.org/browse/HUE-1672.
Did you install setuptools 0.6?
pip installs python-setuptools (0.6.34-0ubuntu1)
