Problem with flask on Mac - David763 - Dec-17-2023 Hi everyone I’m running Mac OS Ventura 13.2 and I’m trying to install flask-mysqldb library using pip on the terminal by running the code : pip install flask-mysqldb but I keep getting the following error : % pip install flask-mysqldb Collecting flask-mysqldb Obtaining dependency information for flask-mysqldb from https://files.pythonhosted.org/packages/31/c4/c91b4a704c1e2467ecfd2c47a9c6f609af37cde7380698aace19dce24f53/Flask_MySQLdb-2.0.0-py3-none-any.whl.metadata Using cached Flask_MySQLdb-2.0.0-py3-none-any.whl.metadata (3.0 kB) Requirement already satisfied: Flask>=1.0.4 in ./anaconda3/lib/python3.11/site-packages (from flask-mysqldb) (2.2.2) Collecting mysqlclient>=2.2.0 (from flask-mysqldb) Using cached mysqlclient-2.2.1.tar.gz (89 kB) Installing build dependencies ... done Getting requirements to build wheel ... error error: subprocess-exited-with-error × Getting requirements to build wheel did not run successfully. │ exit code: 1 ╰─> [30 lines of output] /bin/sh: pkg-config: command not found /bin/sh: pkg-config: command not found /bin/sh: pkg-config: command not found Trying pkg-config --exists mysqlclient Command 'pkg-config --exists mysqlclient' returned non-zero exit status 127.

RE: Problem with flask on Mac - ndc85430 - Dec-18-2023 The first few lines of your output say Does pkg-config installed on MacOS, or do you have to install it from Homebrew or something?

RE: Problem with flask on Mac - ndc85430 - Dec-18-2023 Are you using Homebrew? brew install pkg-config should do it (see https://formulae.brew.sh/formula/pkg-config). If you're not using Homebrew, I'm not sure.

It says command not found,I even tried it with the $ sign as explained in the link you posted RE: Problem with flask on Mac - ndc85430 - Dec-18-2023 You need to install Homebrew if you haven't already - see https://brew.sh/. No, you don't type the $. That's just an example of the shell prompt.

That's just an example of the shell prompt. Didn’t fix it RE: Problem with flask on Mac - menator01 - Dec-19-2023 You may be better off installing pymysql and using that. I'm on ubuntu linux and get the same install problem. RE: Problem with flask on Mac - menator01 - Dec-19-2023 This link allowed me to install without errors https://github.com/PyMySQL/mysqlclient#install RE: Problem with flask on Mac - snippsat - Dec-19-2023 Now you are using Anaconda3 then most a environment be activated, (base) is the default one.Are a environment activated? It's best is to make new environment and not use (base) for this.As you see here it goes over to a other version of Python that's not Anaconda. /private/var/folders/rv/n6zb4_qs6ql1r8cc2gs7w8_w0000gn/T/pip-build-env-nqoa4iyp/overlay/lib/python3.11/sThis should of course not happen as you install to Anaconda,see the Path to Python 3.11 is different. /Users/amirhosein/anaconda3/lib/python3.11/site-packages/pipExample is i use Miniconda(work the same as Anaconda) and then first active a environment then it works.
