Installing mysqlclient in Python 3.6 in windows

问题

I want to install MySqlclient on my windows system. I am Currently using Python 3.6. After going through the various post over Stackoverflow, I could Not find the correct way. This is what I have done so far:

1) Installation by using pip pip install mysqlclient. Error:

Microsoft Visual C++ 14.0 is required. Get it with \"Microsoft Visual C++ Build Tools\" http://landinghub.visualstudio.com/visual-cpp-build-tools

I already have Microsoft Visual C++ installed on my laptop. Some are saying you need 2015 edition.

2) Installation by using wheel file pip install mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl. Error:

Requirement mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl looks like a filename, but the file does not exist. mysqlclient-1.3.13-cp36-cp36m-win_amd64.whl is not a supported wheel on this platform.

2.1) Changing the whl file to different version pip install mysqlclient-1.3.13-cp36-cp36m-win32.whl. Error:

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: \'C:\\\\Users\\\\Foxtrot\\\\Desktop\\\\finaltest\\\\mysqlclient-1.3.13-cp36-cp36m-win32.whl\'

Other things that are done: updated setuptools, updated wheel.

回答1:

I can't find mysqlclient-1.3.13's whl file on PyPi. So you need to compile it from source. Unfortunately it's not easy. I'm not Windows guy, so I only can recommend guide like this

Had the same problem, searched the web etc. Here this answer:

mysql-python install error: Cannot open include file 'config-win.h'

It has all the instructions. In short go to this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient:

There you will find mysqlclient‑1.3.13‑cp36‑cp36m‑win32.whl mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl

Download the correct file for your platform.

Then use your downloaded wheels file with pip and your done:

pip install c:\mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl

The https://www.lfd.uci.edu/~gohlke/pythonlibs has lots of lots of compiled libaries to solve the problem of building them from source yourself. They even compile them for python 3.7 :)

Alternative Solution

You can also download Visual C++ Build Tools and then you should be able to install every (at least to my knowledge) version of mysqlclient with pip. To do this go to this site: https://www.scivision.co/python-windows-visual-c++-14-required/ there you can find out which version of Build Tools you need and you can also find a link to download the installer. Be aware though Build Tools require more than 4GB of free disk space.

The error means that the package has not yet been compiled for your versions of OS and Python. So pip tries to build it from the source for you.

There are two possible solutions.

1. The first option is to install the most recent version of Microsoft Visual C++ Build Tools. Just go ahead and download it from the Microsoft website. Then pip should be able to compile the package.

2. Another option is using an unofficial binary. As mentioned here, a resource proved to be useful is https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python . Just download the pre-compiled package and install it using

   pip install c:\path-to-a-pre-compiled-package

I am using python3.7 on Windows 10 operating system. I had same issue and after a long research I had installed it successfully.

Install "Microsoft Visual C++ Build Tools" AND My OS is having 64 bit operating system but still then it need to install 32 bit version "mysqlclient‑1.4.2‑cp37‑cp37m‑win32.whl"

Download binary wheels from "https://www.lfd.uci.edu/~gohlke/pythonlibs/" and run command

pip install [path_to_downloaded_file] eg: C:\Users\Ds\mysqlclient-1.4.2-cp37-cp37m-win32.whl

use pipenv instead of pip if you are using virtual environment.

Had the same problem just day. Tried to install mysqlclient on a Windows Server R2.

[...]

Tl;dr

1. "MySQL Connector C 6.1" was installed in the wrong directory: "C:\Program Files\MySQL" instead of "C:\Program Files (x86)\MySQL" where it should be for me.
   --> Copied "MySQL Connector C 6.1" to "C:\Program Files (x86)\MySQL" Directory.

2. "C:\Users\MoBoo\AppData\Local\Temp" was Read-Only: Therefore pip couldn't compile files into Temp dir.
   --> Allow Write access to "C:\Users\MoBoo\AppData\Local\Temp" Directory.

Here is what worked for me. I uninstalled mysql and re-installed it.

pip uninstall mysqlclient

Then simply re-install, so it picked the current version "1.4.2.post1"

pip install mysqlclient

Which interestingly, works straightaway.
