I'm trying to make an autofiller using selenium, but it couldn't be done. so I decided to use undetected chromedriver to finish the automation.
I am having some difficulty here to import the undetected-chromedriver.
I already downloaded it by inputting the command line: pip install undetected-chromedriver
But when I put the import undetected_chromedriver as uc, the complier doesn't recognize it.
Below is the Error message after trying to import undetected-chromedriver:
import undetected_chromedriver as uc
ModuleNotFoundError: No module named 'undetected_chromedriver'
Use the following command to check if the undetected_chromedriver package is in the list
pip list
or
pip3 list
Try the following
# navigate into the project directory with your python script
cd presearch
# create virtual environment
python3 -m venv venv
# activate the virtual environment
source venv/bin/activate
# install required pip packages
pip3 install undetected-chromedriver
If you have multiple python versions installed, you might check if you actually installed it in the right one.

To install cx_Oracle latest version 8.0.0 in your own laptop, you need the following components already installed:
Python 3x
An Oracle Instant Client version 11g or higher. Refer to download the instant client version to this link
https://www.oracle.com/database/technologies/instant-client/downloads.html
Steps to Download and Install cx_Oracle Package for Python on Windows. In my case, I like better the version available in GitHub
https://github.com/oracle/python-cx_Oracle
1.Click on the Download cx_Oracle link to download the package from Github. It will download a zip file into your laptop.
2.Extract the zip file to a folder on Windows. For example, C:\cx_oracle.
3.Now open the command prompt and change the current directory to the C:\cx_oracle directory to install cx_Oracle package.
4.Then run the following command.
python -m pip install cx_Oracle --upgrade pip
It will install the cx_Oracle package for Python on Windows, and you will get the messages as shown below.

Installing collected packages: pip
Found existing installation: pip 10.0.1
Uninstalling pip-10.0.1:
Successfully uninstalled pip-10.0.1
Successfully installed pip-18.0
Important if you have more than one version of Python, use the one associated to Jupyter notebook.
You need to import the package first:
pip install cx-Oracle
In simple words for anaconda users
while installing the package use small case letters source
conda install -c conda-forge cx_oracle
now while importing the package use init cap as
import cx_Oracle
I'm trying to use pip to install a package. I try to run pip install from the Python shell, but I get a SyntaxError. Why do I get this error? How do I use pip to install the package?
>>> pip install selenium

SyntaxError: invalid syntax
pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium.
The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands.
Use the command line, not the Python shell (DOS, PowerShell in Windows).
C:\Program Files\Python2.7\Scripts> pip install XYZ
If you installed Python into your PATH using the latest installers, you don't need to be in that folder to run pip
Terminal in Mac or Linux
$ pip install XYZ
As #sinoroc suggested correct way of installing a package via pip is using separate process since pip may cause closing a thread or may require a restart of interpreter to load new installed package so this is the right way of using the API: subprocess.check_call([sys.executable, '-m', 'pip', 'install', 'SomeProject']) but since Python allows to access internal API and you know what you're using the API for you may want to use internal API anyway eg. if you're building own GUI package manager with alternative resourcess like https://www.lfd.uci.edu/~gohlke/pythonlibs/
Following soulution is OUT OF DATE, instead of downvoting suggest updates. see https://github.com/pypa/pip/issues/7498 for reference.
UPDATE: Since pip version 10.x there is no more get_installed_distributions() or main method under import pip instead use import pip._internal as pip.
UPDATE ca. v.18 get_installed_distributions() has been removed. Instead you may use generator freeze like this:
from pip._internal.operations.freeze import freeze
print([package for package in freeze()])
# eg output ['pip==19.0.3']
If you want to use pip inside the Python interpreter, try this:
import pip
package_names=['selenium', 'requests'] #packages to install
pip.main(['install'] + package_names + ['--upgrade'])
# --upgrade to install or update existing packages
If you need to update every installed package, use following:
import pip
for i in pip.get_installed_distributions():
pip.main(['install', i.key, '--upgrade'])
If you want to stop installing other packages if any installation fails, use it in one single pip.main([]) call:
import pip
package_names = [i.key for i in pip.get_installed_distributions()]
pip.main(['install'] + package_names + ['--upgrade'])
Note: When you install from list in file with -r / --requirement parameter you do NOT need open() function.
pip.main(['install', '-r', 'filename'])
Warning: Some parameters as simple --help may cause python interpreter to stop.
Curiosity: By using pip.exe you actually use python interpreter and pip module anyway. If you unpack pip.exe or pip3.exe regardless it's python 2.x or 3.x, inside is the SAME single file __main__.py:
# -*- coding: utf-8 -*-
import re
import sys
from pip import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
sys.exit(main())
To run pip in Python 3.x, just follow the instructions on Python's page: Installing Python Modules.
python -m pip install SomePackage
Note that this is run from the command line and not the python shell (the reason for syntax error in the original question).
I installed python and when I run pip command it used to throw me an error like shown in pic below.
Make Sure pip path is added in environmental variables. For me, the python and pip installation path is::
Python: C:\Users\fhhz\AppData\Local\Programs\Python\Python38\
pip: C:\Users\fhhz\AppData\Local\Programs\Python\Python38\Scripts
Both these paths were added to path in environmental variables.
Now Open a new cmd window and type pip, you should be seeing a screen as below.
Now type pip install <<package-name>>. Here I'm installing package spyder so my command line statement will be as pip install spyder and here goes my running screen..
and I hope we are done with this!!
you need to type it in cmd not in the IDLE. becuse IDLE is not an command prompt if you want to install something from IDLE type this
>>>from pip.__main__ import _main as main
>>>main(#args splitted by space in list example:['install', 'requests'])
this is calling pip like pip <commands> in terminal. The commands will be seperated by spaces that you are doing there to.
If you are doing it from command line,
try -
python -m pip install selenium
or (for Python3 and above)
python3 -m pip install selenium
I am trying to install pandas module on PyCharm. When i try to install it it gave me this error: "ModuleNotFoundError: No module name 'Cython' " (Screen: https://prnt.sc/qafwcy)
So i went on the CMD to try to install the Cython package with this command: py -m pip install Cython , which gave me an other error: "The script, f2py.exe is install in 'C:\xxx.xxxx, which is not a PATH. (Screen: https://prnt.sc/qafvx3)
Does anyone had the same problem and know how to fix it?
Thank you
Pycharm uses a virtual environment - one separate from your python install on your computer. This is to isolate your development environment from the one you would use on your computer.
Enter your pip commands here instead:
I have python 3.6 and pip 9.0.3 i am trying ton install numpy in pycharm
but it's show me message I don't know what i missed and to to fix it .I also try by command prompt .but not solved my problem
Assuming that you have just one Python version installed, Try upgrading the pip utility python -m pip install --upgrade pip
Or,
If you have multiple Python installations, make sure you have PyCharm pointing to the Python you intend to use.
Ways to install numpy (or any python module):
Command Line: pip install numpy
Graphical (via PyCharm): File -> Settings -> Project -> Project Interpreter -> click on green + icon -> search and select numpy -> Install Package
On Ubuntu 10.10, I am unable to install lxml to python 2.7. Here are the steps I take.
sudo su -
apt-get install python2.7
apt-get install python-lxml
Note when running the install for python-lxml package, the following appeared:
INFO: using unknown version '/usr/bin/python2.7' (debian_defaults not up-to-date?)"
Importing the module in python2.6 (the version that comes standard with Ubuntu) works. However, importing the module under python2.7 does not. So how does one install Python modules to a non-default Python installation?
Try to install libxml2, libxml2-dev, libxslt, libxslt-dev, python-dev. These are header files. Then try to install lxml again.
On Ubuntu 10.10 the python packages installed from the repositories get installed to /usr/lib/python2.6/dist-packages so one option is to add this path to your $PYTHONPATH environmental variable so python2.7 will look to the python2.6 directory for the libs.
What I've done on Ubuntu 10.10 is add
export PYTHONPATH="$PYTHONPATH:/usr/lib/python2.6/dist-packages"
to my .bashrc file, and also to my .gnomerc file. This sets the $PYTHONPATH for python instances started from the shell or from the gnome desktop. You should then be able to import the python libs which you have installed from the Ubuntu repositories in python2.7.
.bashrc and .gnomerc are both located in your home directory; you might have to create .gnomerc if it doesn't already exist. And one caution: I had a syntax error in my .gnomerc which stopped the gnome desktop from loading, and I couldn't log in. I had to use a recovery console to fix this syntax error and then I could log in again.
This seems a little hackish to me, so I'm interested in hearing better solutions.
Another solution might be to use the following code:
try:
from lxml import etree
except ImportError:
try:
# Python 2.5
import xml.etree.cElementTree as etree
except ImportError:
try:
# Python 2.5
import xml.etree.ElementTree as etree
except ImportError:
try:
# normal cElementTree install
import cElementTree as etree
except ImportError:
try:
# normal ElementTree install
import elementtree.ElementTree as etree
except ImportError:
print("Failed to import ElementTree from any known place")
[Source]
This will import lxml if it is available, or the original ElementTree otherwise.
I use this code for my application on Google App Engine (using Python 2.7): on the server it will use lxml, on my machine it will use ElementTree.
I have one easiest trick Just open synaptic package manager type "python-lxml" in search box it will show you all the dependencies and available packages select packages which you want to install and hit apply.
