Syntax Error from 'pip install' in python + command line - python

Okay, so, I'm running Python 3.4.3 with pip 9.0.1, with the setuptools and wheel.
I'm running this inside JetBrains PyCharm Professional 2017.2.3.
The issue I'm having is trying to install the twitter api packages from this tutorial (ya I'm a n00b) http://wiki.openhatch.org/Twitter
I'm struggling with installing the 4 dependencies mentioned in the first part of the tutorial (httplib2, simplejson, oauth2 and python-twitter)
Honestly, I'm just getting back into programming and this is a project I'd like to complete.
So, I need help with:
Installing pip, and how to use it, and where (python shell or command line or)
the dev.twitter.com website (and where to find what I need from there)
Any help is massively appreciated and sorry if I sound really n00by, but do correct me where I'm using incorrect terms etc because that's how I learn I guess :)

If you haven't got pip installed, find your python installation file.Execute it and choose 'Change Python Installation'. Now choose 'pip' to install and 'add python.exe to path'. Wait for it to finish. Now run windows command line and type:
pip install package_name
Sometimes you may experience that a package isn't available on pip or doesn't work.There are 2 common (not always working) ways to install a package without making pip download the file:
1) A package may be available as a .whl file for download.Download it.Now find it and copy its name .Open a command line in dictionary where it is located and type
pip install **now paste the filename and add .whl**'
2)A package is available as a zip file.Packages are often packed into a zip file.Download the file and extract it.Open a command line in it's directory.You may see setup.py file.Run
python setup.py install
When finished installing pip and adding python to path,you can run:
pip install httplib2 simplejson oauth2 python-twitter
Done.

Once you have pip installed, open the command prompt and just type pip install name_of_the_extension.
In this case, pip install httplib2 will install this package.
I believe you have pip installed on your computer, so it shouldn't be a problem to install the 4 packages you need.

How do I install a Python library? [duplicate]

I'm having a hard time setting up python packages. EasyInstall from SetupTools is supposed to help that, but they don't have an executable for Python 2.6.
For instance to install Mechanize, I'm just supposed to put the Mechanize folder in C:\Python24\Lib\site-packages according to INSTALL.txt, but runnning the tests does not work. Can someone help shed some light on this? Thanks!
The accepted answer is outdated. So first, pip is preferred over easy_install, (Why use pip over easy_install?). Then follow these steps to install pip on Windows, it's quite easy.
Install setuptools:
curl https://bootstrap.pypa.io/ez_setup.py | python
Install pip:
curl https://bootstrap.pypa.io/get-pip.py | python
Optionally, you can add the path to your environment so that you can use pip anywhere. It's somewhere like C:\Python33\Scripts.
Newer versions of Python for Windows come with the pip package manager. (source)
pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4
Use that to install packages:
cd C:\Python\Scripts\
pip.exe install <package-name>
So in your case it'd be:
pip.exe install mechanize
This is a good tutorial on how to get easy_install on windows. The short answer: add C:\Python26\Scripts (or whatever python you have installed) to your PATH.
You don't need the executable for setuptools.
You can download the source code, unpack it, traverse to the downloaded directory and run python setup.py install in the command prompt
Starting with Python 2.7, pip is included by default. Simply download your desired package via
python -m pip install [package-name]
As I wrote elsewhere
Packaging in Python is dire. The root cause is that the language ships without a package manager.
Fortunately, there is one package manager for Python, called Pip. Pip is inspired by Ruby's Gem, but lacks some features. Ironically, Pip itself is complicated to install. Installation on the popular 64-bit Windows demands building and installing two packages from source. This is a big ask for anyone new to programming.
So the right thing to do is to install pip. However if you can't be bothered, Christoph Gohlke provides binaries for popular Python packages for all Windows platforms http://www.lfd.uci.edu/~gohlke/pythonlibs/
In fact, building some Python packages requires a C compiler (eg. mingw32) and library headers for the dependencies. This can be a nightmare on Windows, so remember the name Christoph Gohlke.
I had problems in installing packages on Windows. Found the solution. It works in Windows7+. Mainly anything with Windows Powershell should be able to make it work. This can help you get started with it.
Firstly, you'll need to add python installation to your PATH variable. This should help.
You need to download the package in zip format that you are trying to install and unzip it. If it is some odd zip format use 7Zip and it should be extracted.
Navigate to the directory extracted with setup.py using Windows Powershell (Use link for it if you have problems)
Run the command python setup.py install
That worked for me when nothing else was making any sense. I use Python 2.7 but the documentation suggests that same would work for Python 3.x also.
Upgrade the pip via command prompt ( Python Directory )
D:\Python 3.7.2>python -m pip install --upgrade pip
Now you can install the required Module
D:\Python 3.7.2>python -m pip install <<yourModuleName>>
pip is the package installer for python, update it first, then download what you need
python -m pip install --upgrade pip
Then:
python -m pip install <package_name>
You can also just download and run ez_setup.py, though the SetupTools documentation no longer suggests this. Worked fine for me as recently as 2 weeks ago.

Or just put the directory to your pip executable in your system path.
As mentioned by Blauhirn after 2.7 pip is preinstalled. If it is not working for you it might need to be added to path.
However if you run Windows 10 you no longer have to open a terminal to install a module. The same goes for opening Python as well.
You can type directly into the search menu pip install mechanize, select command and it will install:
If anything goes wrong however it may close before you can read the error but still it's a useful shortcut.

Installation: Reportlab: "ImportError: No module named reportlab.lib"

I've installed reportlab, via
pip install reportlab
(also tried via
easy_install reportlab
)
..but I get the above error. There are other RL imports before that - it's the .lib that it's objecting to. I've had RL working great in the past, but IT reimaged my computer, and I'm trying to rebuild it. The script works fine, but there's something funky with the RL install, I think.
Reportlab: 3.3.0
Most of the times errors like this are caused by an broken package, either in the package it self or in one of it's dependencies.
The best way to resolve such a issue is to force-reinstall the package, it will reinstall the package and its dependencies potentially repairing the package.
To force-reinstall reportlab use:
pip install --upgrade --force-reinstall reportlab
If the above solution doesn't work for you then make sure you dont have any other module named reportlab.py in your current directory.
Another alternative you can do this in windows commandline
pip uninstall reportlab
then create an account for reportlab here is the link https://www.reportlab.com/accounts/register/
then copy paste this in the windows commandline
pip install -ihttps://www.reportlab.com/pypi -U reportlab
when it prompts you for a user and password use the one you just registered
Download the latest version of python, ensure it's a 64-bit python package, and change the python interpreter in VSC.
View - Command Pallette - Type "Select Interpreter" - Click it and choose for example "Python 3.8.0 64-bit"
It's also a good idea to install the latest version:
pip install reportlab==3.6.11
Check if you have 2 versions of Python - That is 2.7 and 3 - in which case you would need to run pip3 instead of pip to run Python3 code
The best way to install ReportLab is use their .exe installer. They have installers for 32bit and 64bit.
https://pypi.org/project/reportlab/2.7/
may be you are missing the module try below command for the same:
pip install --upgrade --force-reinstall reportlab

How to install pip in python 3.4 on windows?

I'm really struggling at installing any python modules (e.g six, yahoo_finance) because they require pip to be installed, but I don't know whether I have pip already or how to install it. Once its installed I don't know what command to type in and where to type it in. Can I install these modules any other way without pip?
I am only a beginner, so sorry if this is a bit basic.
Thanks in advance
pip comes already bundled with python 3.4 It will be in your scripts directory C:\Python34\Scripts\
Add it to your Environment variables and you can run it from any directory or else open the directory mentioned above in command prompt and run pip install ... to install whatever you want
First, make sure you have it installed, if not follow the instructions below. Type which pip, and if it doesn't list an URL, it means it's not installed yet.
Go here https://bootstrap.pypa.io/get-pip.py and download the file.
Then open terminal and go to your downloads folder (or wherever you downloaded it to) and type python get-pip.py to execute the script. If you get an error that says OSError: Permission Denied, or something similar, run it with administrator permissions.
If the installation is successful, you should now have pip installed on your computer. Type pip --version to make sure you have it installed.
To install six and yahoo_finance, type:
pip install six
and
pip install yahoo-finance
If something goes wrong update your question.
From Installing Python Modules:
pip is the preferred installer program. Starting with Python 3.4, it is included by default with the Python binary installers.
Emphasis mine
If you already installed it by default you should be able to use it.
Just open the command line and type python -m pip install SomePackage.

Python (anaconda) add packages with pip behind proxy

sorry for asking a probalby stupid question, however, I am completely new to setting up/installing python packages, i.e. I have never done it.
So far I installed anaconda3 and worked with the pre installed packages. Now I need the google api pyhon client.
I do not even know whether pip is installed in the anaconda package but I assume it.
What have I tried so far:
In Windows cmd:
1. pip install --upgrade google-api-python-client
2. pip install -- proxy="XXX.XXX.XX.X:XX" -- upgrade google-api-python-client
3. export https_proxy="...."
pip install --upgrade google-api-python-client
I get the following errors:
cannot fetch index base url https://pypi.python.org/simple
unknown command
unknown command
In addition I tried to download the google_api_python_client and unzipped it.
However, I do not know how to proceed here.
BTW: Here in my company we are still on XP
Any help would be highly appreciated!
THANK YOU
Would like to add to the answer by #alok-nayak that you should use the following:
python setup.py install
Leads to:
Installed ~/anaconda/lib/python2.7/site-packages/google_api_python_client-1.4.2-py2.7.egg
After unzipping google_api_python_client. You should run the setup.py file
python setup.py
Also you can edit ".condarc" file in your home folder, as explained here http://conda.pydata.org/docs/config.html . enter your proxy details there

how to install virtualenv and/or pip

Someone please tell me I'm not crazy, becuase I really feel like I am right now.
Ok so, I'm trying to setup a webapp with python and django using heroku, but I've hit quite an odd obstacle.
It wants me to setup a virtualenv using the command $ virtualenv venv --distribute, which is all well and good except:
yeh, so naturally I googled how to install virtualenv and I found this:
But, of course:
So I continued my search by trying to find out how to install pip and I found this:
Aaaaaaand that's when I completely lost my marbles because apparently you need to install pip to install virtualenv to install pip. (maybe not, but that's why I'm a noob and I need help).
But then I took another look at the vitualenv installation guide, and found that I could download it and install it manually, so I extracted all the files from the downloaded archive into my python33 folder and used setup.py install. And I got this:
So I changed the line in that file to except ValueError as e and I got another error from a different python file in that same folder so I reverted the change I made and decided that it probably was not a good idea to meddle with those scripts.
Please, any help at all to do with setting up a free server with python and django would be greatly appreciated. Furthermore, I am sorry if my question is stupid, or incorrectly tagged.
You are following install guides for linux. You should try to find an install guide for pip and virtualenv on windows. First install pip systemwide and then use pip to install virtualenv systemwide. Then start using virtual environments.
Start with How to install pip on W$ and Python and virtualenv on W$. An alternative is the Hitchhiker's guide to python.
Edit
As Ron Elliott states in the comments,
you'll need to point your path to C:\Python2x\Scripts or C:\Python3x\Scripts in order to pick
up easy_install and pip as well as any other script executables
installing to that directory.
But then I took another look at the vitualenv installation guide, and
found that I could download it and install it manually, so I extracted
all the files from the downloaded archive into my python33 folder and
used setup.py install.
You downloaded the package and run setup.py install in wrong folder, that's why it didn't work.
You should:
Download the archive virtualenv-1.10.tar.gz to a Downloads folder (or where ever you want)
Extract it, you will have a folder name virtualenv-1.10
Go to (cd) the extracted folder
Run command: python setup.py install
Anyway I would recommend installing setuptools and pip first, then you can install virtualenv from pip: pip install virtualenv.
