使用conda安装flask-mysql

Question

How should I install flask-mysql using conda?

Monas-MacBook-Pro:flask_app mona$ conda install -c auto flask-mysql
Fetching package metadata .............

PackageNotFoundError: Packages missing in current channels:

  - flask-mysql

We have searched for the packages in the following channels:

  - https://conda.anaconda.org/auto/osx-64
  - https://conda.anaconda.org/auto/noarch
  - https://repo.continuum.io/pkgs/main/osx-64

I can install it using pip but I wonder if there's a hack to install it using conda as well:

Monas-MacBook-Pro:flask_app mona$ pip -V
pip 9.0.1 from /Users/mona/anaconda/lib/python3.6/site-packages (python 3.6)
Monas-MacBook-Pro:flask_app mona$ pip install flask-mysql

Answer 1

Installing flask-mysql using the command conda install -c auto flask-mysql is currently only supported by Linux. If you check this link , you'll find this package is only available for linux-32 and linux-64

I am assuming you want to install a database toolkit for Flask. May I suggest you use SQLAlchemy ? It supports MySQL starting with version 4.1 through modern releases. Follow this link for more details: http://docs.sqlalchemy.org/en/latest/dialects/mysql.html

The conda command to install Flask and SQLAlchemy is:

conda install -c conda-forge flask-sqlalchemy

Or, to get python + flask + mysql working on Mac you can simply type in these commands:

pip install flask

Then,

sudo su
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
pip install MySQL-python

Finally, make a symlink

cd /usr/local
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

I hope this helps! :)

I can confirm that if you install with pip install flask-mysql , you will be able to import the package from within your flask environment (after the source activate command). There is no working conda install package for it.
