error when install mysqlclient using pip to MacOS Bigsur - mysql

Question

I've tried common solutions written for mysqlclient error
1st try: brew install mysql-connector-c
2nd try:
LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient
3rd try: brew install zstd
And mysql server is well-running.
But the error is not being fixed..
I am getting clang linker error saying library not found for -lzstd
clang -bundle -undefined dynamic_lookup -L/usr/local/opt/readline/lib -L/usr/local/opt/readline/lib -L/Users/user/.asdf/installs/python/3.7.10/lib -L/usr/local/opt/llvm/lib -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -L/usr/local/opt/readline/lib -L/usr/local/opt/readline/lib -L/Users/user/.asdf/installs/python/3.7.10/lib -L/usr/local/opt/llvm/lib -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -L/usr/local/opt/llvm/lib -I/usr/local/opt/llvm/include build/temp.macosx-11.2-x86_64-3.7/MySQLdb/_mysql.o -L/usr/local/Cellar/mysql/8.0.25_1/lib -lmysqlclient -lzstd -lresolv -o build/lib.macosx-11.2-x86_64-3.7/MySQLdb/_mysql.cpython-37m-darwin.so
ld: library not found for -lzstd
clang-12: error: linker command failed with exit code 1 (use -v to see invocation)

In my case I did not had the sudo access so installed brew for my user
Check if your brew is not in default location
do this to check where you have installed brew
brew --prefix
output: Users/helloWorld/homebrew
use the output of above to set the ld flags and cpp flags
for example for me ssl and zstd libs were not found so this is what i did:
export LDFLAGS="-L/Users/helloWorld/homebrew/lib -L/Users/helloWorld/homebrew/opt/openssl/lib"
export CPPFLAGS="-I/Users/helloWorld/homebrew/include -I/Users/helloWorld/homebrew/opt/openssl/include"
and then do the pip install
pip3 install mysqlclient
