Installation error

[ZacharieALES]

Hello,

When running "pip3 install -r requirements.txt" I get the following error:

...
Collecting cairocffi>=0.9.0

  Using cached cairocffi-1.1.0.tar.gz (68 kB)

  WARNING: Generating metadata for package cairocffi produced metadata for project name unknown. Fix your #egg=cairocffi fragments.

Do you know what I did wrong? (or should do?)

You solved the problem (issue is closed)?

[ZacharieALES]

I thought I solved it, but no I still have this problem...

I tried to do installation steps 1 to 4. I also tried just step 4 and still have the same error.

[Peer David]

I pushed a workaround as it seems that this problem is caused by the weasyprint package. Can you please try to pull the changes, delete the env folder and install it again?

Note: With this workaround weasyprint is not installed and only imported if needed i.e. if it is not installed you can not copy a url and paste it directly into RemaPy as website parsing is not working...

[ZacharieALES]

Thank you for your help.

I was now able to install all the requirements (by deleting the env folder and using steps 1 to 4). However, when I execute rema.py I get:

(env) zach@zach-dell-ensta ~/10_Soft/remapy/remapy $ ./rema.py

Do you use a python version < 3.6 (f-strings are supported since 3.6)?
But, its not really necessary to use f-strings so I changed those. Latest version should work...

I close this issue now due to inactivity. Feel free to reopen it.
