Python pip install mysqlclient

Question

So I downloaded Python 32 bits 1st, then I did python -m pip install mysqlclient.

I needed Visual C++ 2015, but I had them cuz my text editors is VSCode. I uninstalled VSCode, installed Visual Studio Build Tools, and I am getting this errors whenever I do python -m pip install mysqlclient.One, cl.exe wasnt added to my path, so I did, but it still says

 error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\bin\\cl.exe' failed with exit status 2

so I downloaded the wheel package for windows, as some other stackoverflow answer said. Whenever I run it, I get

I tried downloading Python 64 bits downloading the wheels, adding cl.exe to path.

It should just work and the package mysqlclient just be installed using pip so I can use it with django.

Answer 1

There isn't an official wheel for the current release 1.4.4, and you are getting errors when you try to install from source.

Since you use 64-bit Python on Windows, you could install 1.4.2.post1, because there is an official wheel for that version.

python -m pip install mysqlclient==1.4.2.post1

Or, you could download an unofficial wheel from https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient, which has wheels for the latest release for 32-bit and 64-bit Python on Windows. Unless you have a particular reason to use 32-bit Python, I suggest you use 64-bit.

For example, you could download mysqlclient‑1.4.4‑cp37‑cp37m‑win_amd64.whl (Python 3.7 64-bit for Windows) then do:

python -m pip install mysqlclient‑1.4.4‑cp37‑cp37m‑win_amd64.whl

Answer 2

I had a similar situation, and i did this:

sudo apt-get install python3-dev libmysqlclient-dev

afterward, inside a virtual environment:

pip3 install mysqlclient

and that was because, i had another problem with the instalation of:

pip3 install flask-mysqldb

Answer 3

FWIW: I also faced this problem on a macOS, with the error:

ld: library not found for -lssl
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'xcrun' failed with exit status 1

A solution (borrowed from this related post) that worked for me was to fix the brew-installed openssl linking:

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
