Hi I am trying to install win10toast and I get this message:
I had this error when I tried to download pywin32 previously, but why is this error popping up whenever I try to install any other package? I used to be able to install packages fine before with the same command
pywin32 is listed as a requirement for the package win10toast (link). So, when you are installing win10toast, pip also tries to install pywin32 which gives you an error.
From the looks of it, you are using a python 3.6 and a 32-bit system, both of which are supported by the latest release (pywin32 302). To resolve the pywin32 error, you could try the following.
Option 1: Considering there are multiple installs and python3 is mapped to python 3.6 installation. (You can check that using python --version)
Install using python -m pip install pypiwin32
If you had a prior successful install on pypiwin32, you could actually try to use: python Scripts/pywin32_postinstall.py -install
Option 2: Download the binary files and install - https://github.com/mhammond/pywin32/releases/tag/b302
Download the appropriate exe and install
Option 3: Download the source files and build:
Download the zip file from: https://github.com/mhammond/pywin32/releases/tag/b302
Unzip the file
Use the command python setup.py install
Update:
I was looking around the pywin32 github repo and found that the same issue is encountered by others too. While an official update is not rolled out, you can try the solution there:
you need to download the wheel found here
Install the whl manually using the command: python -m pip install C:/some-dir/pywin32-302.1-cp36-cp36m-win32.whl
I am having problems with installing a python package (pandas) on Ubuntu 18.04 to a specific Python (3.6.5) distribution in Salome_meca located in:
/home/username/salome_meca/V2019.0.3_universal/prerequisites/Python-365/lib/python3.6/os.py
if I run:
sudo python3.6 -m pip install --install-option="--prefix=/home/username/salome_meca/V2019.0.3_universal/prerequisites/Pandas-120" pandas
It raises an error:
Requirement already satisfied: pandas in /usr/lib/python3/dist-packages
And I cannot import this module as the python (3.6.5) distribution in Salome_meca cannot find it, when I run the code in the Salome_meca invornment.
Try using the -t (target switch) as seen here
sudo python3.6 -m pip install -t =/home/username/salome_meca/V2019.0.3_universal/prerequisites/Pandas-120
The problem was solved by firstly input in terminal ./salome shell and then pip3 install pandas and this installed pandas under the python distribution within salome_meca. The only problem is that it was not installed in the correct folder (but works anyway). Probably one should set also the target dir, and then the command should be: pip3 install pandas --target=/home/lskrinjar/salome_meca/V2019.0.3_universal/prerequisites/Pandas-115
i have been trying to install module for python-3.6 through pip. i've read these post from stackoverflow and from python website, which seemed promising but they didn't worked for me.
Install a module using pip for specific python version
python website
I've added python3.6 main folder,Scripts and Lib to PATH and i've tried these commands.But somehow they refer to anaconda installations.
C:\Program Files (x86)\Python36-32\Scripts> pip3 install xlrd
C:\Program Files (x86)\Python36-32\Scripts> pip install xlrd
C:\Program Files (x86)\Python36-32\Scripts> pip3.6 install xlrd
C:\Program Files (x86)\Python36-32\Scripts> py -3.6 -m pip install xlrd
C:\Program Files (x86)\Python36-32\Scripts> py -3 -m pip install xlrd
but they give same answer.
Requirement already satisfied: xlrd in c:\programdata\anaconda3\lib\site-packages (1.1.0)
to install package for a specific python installation, you need a package installer shipped with that installation, in your case, pip is installed by an anaconda installation, use pip.exe or easy_install.exe from this python3.6 installation's Scripts directory instead.
First, Uninstall all the versions you have!
then go to the library https://www.python.org/downloads/
Select the required vesrsion MSI file. Run as administrator!
i think as my python was 3.6 also my anaconda distribution, So anaconda was automatically taking over all commands. i installed python 3.7 with anaconda 3.6 and it worked fine as it was mentioned in python website
I'm trying to install lxml for Centos6.3, due to this issue. It looks like I've got a conflicting version of pip. The standing solution seems to re-install pip for the correct version of python.
My main issue is that all the methods I've found for installing pip require an internet connection. Is it possible to download pip install files, and then run pip install -U pip and point it at the right files?
The PyPI page for pip only has pip6.11 as a .whl. I've tried running pip install -U pip-6.1.1-py2.py3-none-any.whl and it's not worked.
I'm stumped. How do I install it?
You could try to download pip and setuptools manually from: https://pypi.org/project/pip/#files and https://pypi.org/project/setuptools/#files
get the python pip script from: https://bootstrap.pypa.io/get-pip.py
after that unzip/untar packages and run:
python get-pip.py --no-index --find-links=/path/to/pip-and-setuptools
or alternatively trying:
python setup.py install when running in unpacked folders

I was looking for a tutorial on how to install Python libraries in the wheel format.
It does not seem straightforward so I'd appreciate a simple step by step tutorial how to install the module named "requests" for CPython.
I downloaded it from: https://pypi.python.org/pypi/requests and now I have a .whl file. I've got Python 2.7 and 3.3 on Windows, so how do I install it so all the other Python scripts I run can use it?
You want to install a downloaded wheel (.whl) file on Python under Windows?
Install pip on your Python(s) on Windows (on Python 3.4+ it is already included)
Upgrade pip if necessary (on the command line)
pip install -U pip
Install a local wheel file using pip (on the command line)
pip install --no-index --find-links=LocalPathToWheelFile PackageName
Option --no-index tells pip to not look on pypi.python.org (which would fail for many packages if you have no compiler installed), --find-links then tells pip where to look for instead. PackageName is the name of the package (numpy, scipy, .. first part or whole of wheel file name). For more informations see the install options of pip.
You can execute these commands in the command prompt when switching to your Scripts folder of your Python installation.
Example:
cd C:\Python27\Scripts
pip install -U pip
pip install --no-index --find-links=LocalPathToWheelFile PackageName
Note: It can still be that the package does not install on Windows because it may contain C/C++ source files which need to be compiled. You would need then to make sure a compiler is installed. Often searching for alternative pre-compiled distributions is the fastest way out.
For example numpy-1.9.2+mkl-cp27-none-win_amd64.whl has PackageName numpy.
If you want to be relax for installing libraries for python.
You should using pip, that is python installer package.
To install pip:
Download ez_setup.py and then run:
python ez_setup.py
Then download get-pip.py and run:
python get-pip.py
upgrade installed setuptools by pip:
pip install setuptools --upgrade
If you got this error:
Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.
Add --no-use-wheel to above cmd:
pip install setuptools --no-use-wheel --upgrade
Now, you can install libraries for python, just by:
pip install library_name
For example:
pip install requests
Note that to install some library may they need to compile, so you need to have compiler.
On windows there is a site for Unofficial Windows Binaries for Python Extension Packages that have huge python packages and complied python packages for windows.
For example to install pip using this site, just download and install setuptools and pip installer from that.
To install wheel packages in python 2.7x:
Install python 2.7x (i would recommend python 2.78) - download the appropriate python binary for your version of windows . You can download python 2.78 at this site https://www.python.org/download/releases/2.7.8/
-I would recommend installing the graphical Tk module, and including python 2.78 in the windows path (environment variables) during installation.
Install get-pip.py and setuptools
Download the installer at
https://bootstrap.pypa.io/get-pip.py
Double click the above file to run it. It will install pip and setuptools [or update them, if you have an earlier version of either]
-Double click the above file and wait - it will open a black window and print will scroll across the screen as it downloads and installs [or updates] pip and setuptools --->when it finishes the window will close.
Open an elevated command prompt - click on windows start icon, enter cmd in the search field (but do not press enter), then press ctrl+shift+. Click 'yes' when the uac box appears.
A-type
cd c:\python27\scripts
[or cd \scripts ]
B-type
pip install -u
Eg to install pyside, type pip install -u pyside
Wait - it will state 'downloading PySide or -->it will download and install the appropriate version of the python package [the one that corresponds to your version of python and windows.]
Note - if you have downloaded the .whl file and saved it locally on your hard drive, type in
pip install --no-index --find-links=localpathtowheelfile packagename
**to install a previously downloaded wheel package you need to type in the following command
pip install --no-index --find-links=localpathtowheelfile packagename
Have you checked this http://docs.python.org/2/install/ ?
First you have to install the module
$ pip install requests
Then, before using it you must import it from your program.
from requests import requests
Note that your modules must be in the same directory.
Then you can use it.
For this part you have to check for the documentation.
Install distribute by downloading and running distribute_setup.py. This will make easy_install available, and from there you can install pip with easy_install pip. Then you can run pip install CAGE. Using pip to install things is a lot easier than messing with manually running setup.py, because pip can do things like:
automatically resolve dependencies
show you a list of all installed packages and their versions
install a set of specified packages from a requirements.txt
upgrade and uninstall packages
work with virtualenv
If you're on Windows, the one downside of pip occurs when there are C library dependencies, as pip will want a C toolchain installed so it can compile things. If that is the case, then there are two options. If there are precompiled binaries on PyPI, then just run easy_install package instead; easy_install knows how to use binary packages. You can also check Christoph Gohlke's site for executable installers of many binary packages. These can also be installed by easy_install if you want to use them with a virtualenv (just point it to the path of the .exe) or you can click and run if you don't care about virtualenv.
The main point is that no matter what route you choose to install packages, at no point are you ever moving around files by hand. You need to get out of the mindset of "I extracted this archive, where do I put these .py files?" That's not how it works. You're either running pip, running easy_install, running setup.py, clicking on an installer package, or using your distribution's installer. At no point are you ever doing anything by hand with the files directly.
Once you have a library downloaded you can execute this from the MS-DOS command box:
python setup.py install
The setup.py is located inside every library main folder.
For windows, there are automatic installer packages available at this site
It includes most of the python packages.
But the best way for it is of course using pip.
You don't need to download exclusively from the website. Just make sure you have pip (which you probably will if you have python installed). Just open your Command Prompt (CMD) and run the command:
pip install pygame
It will automatically download the correct whl version of pygame compatible with your configuration of PC. Make sure you remember the version which appears while "downloading" as this is the compatible version of .whl packages you shall be looking for in the future.
Simple steps to install python in Ubuntu:
Download Python
$ cd /usr/src
$ wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
Extract the downloaded package
$ sudo tar xzf Python-3.6.0.tgz
Compile Python source
$ cd Python-3.6.0
$ sudo ./configure
$ sudo make altinstall
Note make altinstall is used to prevent replacing the default python binary file /usr/bin/python.
check the python version
# python3.6 -V

How to add/use libraries in Python (3.5.1)
but no problem will rewrite it again
if u have or you can create a file requirements.txt which contains the libraries that you want to install for ex:
numpy==1.14.2
Pillow==5.1.0
You gonna situate in your folder which contains that requirements.txt in my case the path to my project is
C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means
now just type
python -m pip install -r ./requirements.txt
and all the libararies that you want gonna install
C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means>python -m pip install -r ./requirements.txt
