cannot load library libcairo

I have problem when trying to run a website in Django:

OSError: no library called "libcairo-2" was found cannot load library 'libcairo.so.2': /lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var cannot load library 'libcairo.so': /lib/x86_64-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Done_MM_Var cannot load library 'libcairo.2.dylib': libcairo.2.dylib: cannot open shared object file: No such file or directory cannot load library 'libcairo-2.dll': libcairo-2.dll: cannot open shared object file: No such file or directory 

Althought the package is installed.

I have installed weasyprint

pip3 install weasyprint python -m pip install WeasyPrint sudo apt-get install build-essential python3-dev python3-pip python3-setuptools python3-wheel python3-cffi libcairo2 libpango-1.0-0 libpangocairo-1.0-0 libgdk-pixbuf2.0-0 libffi-dev shared-mime-info 

I also tried

sudo apt install libcairo2-dev sudo apt install libgirepository1.0-dev 

I have Lubuntu system. Any ideas how can I fix it? Thanks in advance

For Ubuntu 20 and Debian based distro, try:

sudo apt-get install libpangocairo-1.0-0 

The solution was to remove libfreetype.so.6 file from home/user/anaconda3/envs/myvenv/lib directory (idea taken from )

For anyone coming here that is getting the error:

/lib/x86_84-linux-gnu/libcairo.so.2: undefined symbol: FT_Done_MM_Var 

Run the command:

sudo find / -name *freetype* 

As Uli Schlachter mentioned it's due to fonts being built in a newer version and used in an older version. I used alis01's comment to find out that for me:

/usr/lib/jvm/java-8-openjdk/jre/lib/amd64/libfreetype.so.6 

was causing the issue. I renamed it to libfreetype.so.6.bak and all has been well since.
