pip install - running build_ext error: [WinError 2] The system cannot find the file specified

I'm trying to install the dialogflow package in Pycharm virtual environment using pip:
pip install dialogflow
and it stops at this error:
running build_ext
error: [WinError 2] The system cannot find the file specified

When I try the same installation in conda virtual environment, it works and there's no error.
I'm using: Windows64, Python 3.8.3, Visual C++ BuildTools 14.0
Any help would be appreciated, thank you

Error while installing notebook using pip

note: I am on linux(ubuntu,mint)
I am trying to install jupyter. But after some searching I realised that the error I have when trying to install jupyter is due to notebook.
So here is the error I have when trying to install notebook using sudo pip install notebook.
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-EKmj0F/scandir/setup.py';
f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();
exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-OB5xPr-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-EKmj0F/scandir/
If you want here is the whole output of pip install notebook.
Thank for answers in advance.
This is the relevant part of the error message:
_scandir.c:14:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

You need the Python headers:
sudo apt-get install python-dev
Your installation process tries to compile an extension with gcc and you seem to be missing the necessary decencies.

Problems installing gx_freeze

I have Ubuntu 14.04 LTS with Python 2.7.6, and I want to install cx_Freeze. I used the command:
pip install cx_Freeze
and I got the error:
fatal error: Python.h: No such file or directory compilation terminated.
so I did:
sudo apt-get install python-dev
but now I'm getting:
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
----------------------------------------
Cleaning up...
Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_emanuele/cx-Freeze/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-Hd6_EY-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_emanuele/cx-Freeze
Storing debug log for failure in /home/emanuele/.pip/pip.log
what does it mean this error and how can I fix it?
