I know that there are some similar questions. But the error still exist after trying those solution. I want to install a model called midi-ddsp and it shows an error.

I've tried to upgrade pip, pip3 install midi-ddsp --use-deprecated=legacy-resolver, pip3 install --upgrade setuptools, easy_install -U setuptools and so on. But neither of them could work. Hope someone could help me, thanks!

I tried these from the answers of another question on StackOverflow but didn't work for me
pip install --user pygames
python -m pip install -u pygame --user
(How to solve the "pip install pygame" issue?)
But in the end, I tried along with --pre. This worked
pip install pygame --pre
Output:
PS C:\\Windows\\system32\> pip install pygame --pre

I think --pre is used for
The pip install command also supports a --pre flag that enables installation of pre-releases and development releases.

I had the same problem when I tried to import an old requirements.txt.
scipy==1.5.1
I checked it from Pypi, changed to 1.9.1 in requirements.txt,
and it works!

I had a similar problem on updating systemd-python with
python3.8 -m pip install --upgrade systemd-python
The error message began with these words:
error: subprocess-exited-with-error
× python setup.py egg_info did not run successfully.
│ exit code: 1
The lines following were quite telling:
Cannot find libsystemd or libsystemd-journal:
Package libsystemd was not found in the pkg-config search path.
Even though the package libsystemd was installed, Python did not find it. I have learnt that often you can solve this "not finding an installed package" by installing the corresponding dev package; in this case it is libsystemd-dev.
After installing the libsystemd-dev the command python3.8 -m pip install --upgrade systemd-python ran smoothly.

I got this exact same error when trying to run:
pip install dotenv
After a lot of hunting around, I realised I got the package name wrong. The correct command was:
pip install python-dotenv
Maybe try googling "pip your-package-name" to find the PyPi page for your package and double check you are using the correct name? It is annoying that the pip error message was not more descriptive.

Trouble installing pyautogui on windows 10

The error actually gives you your answer by their recommendation to use the --user option. I run into this as well, if you want to install something without admin privileges. Just add the --user flag to the end of your pip command. This will limit the installation to the current user and not require administrator privileges.
Try this:
pip install pyautogui --user
The second error also gives you the answer of what to do.
pip install --upgrade pip
or, if needed...
pip install --upgrade pip --user

Multiple packages cannot install on PyCharm

I am trying to use PyCharm for my python 3 coding on my Linux, and it works great 90% of the time, but I notice that on occasion I cannot import certain packages. For example, when I click Settings->Project->Python Interpreter and try to install 'opencv-python', I get this error:
AttributeError: module 'setuptools.build_meta' has no attribute '__legacy__'
When I try to install opencv-python with pip I get this message:
$ pip install opencv-python
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: opencv-python in ./.local/lib/python3.6/site-packages (4.5.1.48)
Requirement already satisfied: numpy>=1.13.3 in ./.local/lib/python3.6/site-packages (from opencv-python) (1.19.2)
There seems to be some discrepency between the packages my computer has installed and the packages that PyCharm has installed. How can I solve this problem?

You are using pip version 10.0.0b2, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
and when I then type pip install --upgrade pip it throws the same error. I've tried reinstalling pip thrice over already and I'm completely out of ideas as to what I can do.
It also does this when I try to install any other package, not jus pyautogui.
Please note that this is only on my OSX machine whilst on my PC it works perfectly fine.

There is always the option downloading a .whl-file and install it with
pip install /some-dir/some-file.whl
I have the same problems as you have with Py 3.4, so i just use Py 3.5. But I know there is no Version of PyAutoGui for 3.x. You can install this package per wheel, and if it is only this package, this'd be ok... Obviously, it does do Pillow...

installing flask in Python on Heroku

I'm trying to follow this guide.
I made virtualenv and installed flask in it:
Requirement already satisfied (use --upgrade to upgrade): Flask in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): Werkzeug>=0.7 in /usr/local/lib/python2.7/dist-packages (from Flask)
Requirement already satisfied (use --upgrade to upgrade): Jinja2>=2.4 in /usr/local/lib/python2.7/dist-packages (from Flask)
After pip freeze > requirements.txt the file contains only:
argparse==1.2.1
distribute==0.6.28
wsgiref==0.1.2
And there is no Flask package. I'm trying to run simple example and got:
ImportError: No module named flask
How to install the package properly?

You need to run pip freeze > reuirements.txt inside your virtualenv. Thus, make sure that your virtualenv was activated correctly. As the Heroku documentation is mostly written from Linux point of view, this may be a little tricky especially on Windows (see a related question):
Windows command-prompt activation is done using venv\Scripts\activate.bat
If you are using Windows PowerShell, you need to run venv\Scripts\activate.ps1 instead.
Note that you need to activate virtualenv for sudo as well. Example:
sudo bash
source venv/bin/activate
pip install Flask
However one of the points in virtualenv is that you don't need sudo. Thus, you could simply omit using sudo and simply just run:
source venv/bin/activate
pip install Flask
