The Python "ModuleNotFoundError: No module named 'pytz'" occurs when we forget
to install the pytz
module before importing it or install it in an incorrect
environment. To solve the error, install the module by running the
pip install pytz
command.
Open your terminal in your project's root directory and install the pytz
module.
# ๐๏ธ in a virtual environment or using Python 2 pip install pytz # ๐๏ธ for python 3 (could also be pip3.10 depending on your version) pip3 install pytz # ๐๏ธ if you get permissions error sudo pip3 install pytz # ๐๏ธ if you don't have pip in your PATH environment variable python -m pip install pytz # ๐๏ธ for python 3 (could also be pip3.10 depending on your version) python3 -m pip install pytz # ๐๏ธ for Anaconda conda install -c conda-forge pytz
After you install the pytz package, try importing it like:
from pytz import timezone import pytz utc = pytz.utc print(utc.zone) eastern = timezone('US/Eastern') print(eastern.zone)
The Python error "ModuleNotFoundError: No module named 'pytz'" occurs for multiple reasons:
pytz
package installed by running pip install pytz
.pytz.py
which would shadow the official module.pytz
which would shadow the imported variable.If the error persists, get your Python version and make sure you are installing the package using the correct Python version.
python --version
For example, my Python version is 3.10.4
, so I would install the pytz package
with pip3.10 install pytz
.
pip3.10 install pytz # ๐๏ธ if you get permissions error use pip3 (NOT pip3.X) sudo pip3 install pytz
Notice that the version number corresponds to the version of pip
I'm using.
If the PATH for pip
is not set up on your machine, replace pip
with
python3 -m pip
:
# ๐๏ธ make sure to use your version of Python, e.g. 3.10 python3 -m pip install pytz
If the "No module named 'pytz'" error persists, try restarting your IDE and development server / script.
You can check if you have the pytz
package installed by running the
pip show pytz
command.
# ๐๏ธ check if you have pytz installed pip3 show pytz # ๐๏ธ if you don't have pip setup in PATH python3 -m pip show pytz
The pip show pytz
command will either state that the package is not installed
or show a bunch of information about the package, including the location where
the package is installed.
If the package is not installed, make sure your IDE is using the correct version of Python.
pytz
package using the incorrect version or your IDE might be setup to use a different version.For example, In VSCode, you can press CTRL + Shift + P
or (โ
+ Shift
+ P
on Mac) to open the command palette.
Then type "Python select interpreter" in the field.
Then select the correct python version from the drop down menu.
If you are using a virtual environment, make sure you are installing pytz
in
your virtual environment and not globally.
You can try creating a virtual environment if you don't already have one.
# ๐๏ธ use correct version of Python when creating VENV python3 -m venv venv # ๐๏ธ activate on Unix or MacOS source venv/bin/activate # ๐๏ธ activate on Windows (cmd.exe) venv\Scripts\activate.bat # ๐๏ธ activate on Windows (PowerShell) venv\Scripts\Activate.ps1 # ๐๏ธ install pytz in virtual environment pip install pytz
Your virtual environment will use the version of Python that was used to create it.
pytz.py
because that would shadow the original pytz
module.You also shouldn't be declaring a variable named pytz
as that would also
shadow the original module.
If the error is not resolved, try to uninstall the pytz
package and then
install it.
# ๐๏ธ check if you have pytz installed pip3 show pytz # ๐๏ธ if you don't have pip setup in PATH python3 -m pip show pytz # ๐๏ธ uninstall pytz pip3 uninstall pytz # ๐๏ธ if you don't have pip setup in PATH python3 -m pip uninstall pytz # ๐๏ธ install pytz pip3 install pytz # ๐๏ธ if you don't have pip setup in PATH python3 -m pip install pytz
Try restarting your IDE and development server / script.
You can also try to upgrade the version of the pytz package.
pip3 install pytz --upgrade # ๐๏ธ if you don't have pip setup in PATH python3 -m pip install pytz --upgrade
