I have a simple project in Pycharm that I am working to load up on a VPS. I would like to utilize pip freeze to build a requirements.txt file and install required packages on the VPS.
Unfortunately, when i activate the venv associated with my project, the output of pip freeze appears to be all of the packages in my default python3 installation, and not my project.
I uploaded a screenshot showing Python Interpreter settings and terminal pip freeze output.
In this case, the venv should only contain pip, selenium, setuptools, urllib3. However, no matter how I try to activate the venv (Pycharm terminal, os x terminal) and deactivate, the output of pip freeze is always the long list of packages that seems to be what I have installed to the normal Python3 environment.
I'm wondering if Pycharm is somehow "overmanaging" my packages or if I;m just going wrong somewhere.
Thank you!
Seems my pip was still the global pip such that when I ran which pip I got /usr/local/bin/pip3. By using the venv pip I was able to get the packages for that project only.
path/to/venv/bin/pip3 freeze
also the following worked.
python3 -m pip freeze

I have a Flask app that with and using venv for my virtual environment. For some reason, which pip has suddenly stopped installing packages in venv/lib/python3.9/site-packages, but to a completely different repository on my system. How do I redirect pip to install packages to the correct path in venv?
instead of using pip as a stand alone command in terminal, i suggest you to use python -m pip instead, here python will be assoicated with the project (in case of Virtual environment) or whole system level (in case docker single app ). This will keep track and tell the system to run all package/module related to python interpreter assoicated with the project only
You can use the -t flag provided by the pip install command.
pip install <package_name> -t <full_location_path>
Is there a possibility to see all pip installed packages in Pycharm?
Because I have the Problem: I write in PyCharm and it works fine, but now I want to move the project to a server... And now I don't know how can I quickly export this
There is such tool provided by PyCharm. You can find it in Tools -> Sync Python Requirements...
Edit:
If after you're receiving an empty file, PyCharm would also suggests you to install certain plugins.
type in terminal
pip list
this will show all the installed requirements in the terminal.
try the following line to update all installed requirements into the requirements.txt file
pip freeze > requirements.txt
then in the server after making a virtualenv run the following command to install all the requirements
pip install -r requiremnets.txt
Use the command pip freeze >requirements.txt locally to import the environment you need into the file,
then use the command pip install -r requirements.txt on the server to install the required environment
I am trying to create a new virtual environment for a tutorial. I have installed virtualenv and virtualenvwrapper multiple times but every time I try creating a new virtual environment my terminal displays - mkvirtualenv: command not found. When I try finding out the version of virtualenv it shows virtualenv: command not found. Something similar was happening with my pip installation as well but then it got resolved when I used some command.
I would like to point out that my PATH seems to be really messed up. The PATH is pointing to /Library/Frameworks/Python.framework/Versions/3.8/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin. Please help.
I saw something else when I use pip show virtualenv it gives me details of the version and the author but when I use virtualenv --version it sends a virtualenv: command not found.
First of all, you will need to install virtualenv as it is a python 2 external dependency.
pip install virtualenv
this will allow you to use virtualenv globally.
Alternatively, you can use from Python 3.5+
python -m virtualenv venv
However if you dont wish to support python 2 you can use venv which is installed on from python 3.3
python3 -v venv venv
Took quite some time to figure it out but what worked for me was to install it using pip3 install instead of pip install
pip3 install virtualenv
I've just installed Python for the first time and I'm trying to reference the win32com module however, whenever I try to import it I get the message "no module name win32com".
Any ideas?
the below plus add pywin32 in PyCharm setting work for me
python -m pip install pywin32
As it is not built into Python, you will need to install it.
pip install pywin
Since win32com is a Windows-specific package, this answer will be geared towards Windows users.
Option 1: Install locally with pipenv (recommended)
You can use a package manager like pipenv to manage your dependencies.
Ensure you have pipenv installed (pip install pipenv).
In your project directory, run pipenv install pypiwin32 to install the package.
Now you can run your code using commands like the following pipenv run main.py
Example main.py code:
import win32com
print(win32com)
Option 2: Install locally with venv (recommended)
If pipenv isn't your thing, you can use the built-in virtual environments.
From your project directory, run python -m venv venv to setup you virtual environment.
Run venv\Scripts\activate.bat from your project directory whenever you want to use this virtual environment (you will see (venv) added to your shell prompt to know it's activated).
Run pip install pypiwin32 from your active virtual environment to install the package.
You can run your code like python main.py so long as the virtual environment is active.
Option 3: Install globally (typically not recommended)
This is not typically recommended, but included anyway.
Using pip install pypiwin32 you can install the package globally.
Then you can run your code with just python main.py.
This will work as well
python -m pip install pywin32
You should try using pip this way:
pip install pypiwin32
It is pypiwin32 which should work.
When working with python projects its always a good idea to create a so called virtual environment, this way your modules will be more organized and reduces the import errors.
for example lets assume that you have a script.py which imports multiple modules including pypiwin32.
here are the steps to solve your problem:
1. depending on you operating system you need to download and install virtualenv package, in debian its as simple as sudo apt install virtualenv .
2. after installing 'virtualenv' package go to your project/script folder and create a virtualenv folder with virtualenv venv it creates a folder named venv in that directory.
3. activate your virtualenv source /path/to/venv/bin/activate if your already in the directory where venv exists just issue source venv/bin/activate
4. after activating your venv install you project dependencies pip install pypiwin32 or pip install pywin
5. run your script, it wont throw that error again :)
I have a MacBook Pro that came pre-installed with python2.7. I later installed python3 and ipython notebook. I installed pip too to install packages, and am able to install packages and run program from python3. However, for another project I need to run code in python2.7, and I am not sure how to install it in python2.7 folder.
I tried using pip for installing packages to 2.7, but it kept giving error saying package already exists. When I check for version of python using --version, I see 2 pythons installed. However, when I check for pip and pip3, both seem to be in th same folder.
Any tips on how to install packages in python2.7, without making any changes to 3.3? I am using python3 and ipython notebooks for another project.
viveks-mbp:~ vivekyadav$ which pip
/Library/Frameworks/Python.framework/Versions/3.3/bin/pip
viveks-mbp:~ vivekyadav$ which pip3
/Library/Frameworks/Python.framework/Versions/3.3/bin/pip3
viveks-mbp:~ vivekyadav$ which python
/usr/bin/python
viveks-mbp:~ vivekyadav$ which python3
/Library/Frameworks/Python.framework/Versions/3.3/bin/python3
You can use the virtualenv to create a kind of sandbox.
$ virtualenv <work-directory>
$ source <work-directory>/bin/activate
The last command initiate your virtual environment, totally isolated from the system. So every pip command will install the package inside this directory.
But you have to run your application inside the virtual environment too.
