Installation threw exception then failed

[DcPublished]

Hi. During finplot installation, it threw the error below and then aborted:

error: metadata-generation-failed

From the log, it appears that it failed on this line:

File "/private/var/folders/7h/q3q6x4vs7n9gn0mdsm3d51xw0000gn/T/pip-build-env-j9i4jpsu/overlay/lib/python3.10/site-packages/pyqtbuild/builder.py", line 67, in apply_user_defaults
raise PyProjectOptionException('qmake',
sipbuild.pyproject.PyProjectOptionException
[end of output]

Note that there is no ".../site-packages/pyqtbuild/..." folder.

I tried several times but could not resolve this. Has anyone else seen this? Any suggestions on fixing this?

Thanks,

Dan.

p.p.s. I'm using a new Mac Pro Max. I have 30 years of experience as a software engineer on Windows, but I just started using a Mac about six weeks ago, so this might be a user error. Any pointers are gratefully accepted.

FinPlot is a nice library, but it's not natively compatible with a Mac M1. I got through the installation issues, but so far, the example plot code throws an error.

At this point, I have neither the time nor energy to try to these issues. So I'm moving to another plotting library like mplfinance or Seaborn.

Dan.

p.s. Some details:

After reviewing the Finplot installation instructions, I noticed that it required PyQt5. When I tried to installed that library, the install failed. After research, I found a solution:

brew install pyqt5
echo 'export PATH="/opt/homebrew/opt/qt@5/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="/opt/homebrew/opt/pyqt@5/5.15.4_1/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

This installed PyQt5, but under Rosetta installation was very slow. What's worse is that the example code throws an error:

fplt.candlestick_ochl(df[['Open', 'Close', 'High', 'Low']])
fplt.show()

I suspect that this is related to the difference between Intel Macs and M1 Macs, or between Macs and Intel machines.

Before heading to bed, I tried on last time and found a solution. If the file is executed in Pycharm's Debug mode, it fails as described above. When executed in "Run" mode, it works. When executed from Terminal, it works.

I have to dig into this further.

After working with the example code further, I'm pleased with FinPlot. It exceeds my expectations and requirements.

Dan.

Hi Dan,

Unfortunately I don't know Mac myself, and there is no other regular maintainer than me. If you'd like to become one, you're more than welcome!
