安装 flask-mysqldb 给出 "mysql_config not found"

Question

我正在尝试在 ubuntu 18.04 上安装 flask-mysql，但我一直收到此错误：

(base) ether@ether:~/Documents/loginsystem$ pip install flask-mysqldb
Collecting flask-mysqldb

        raise EnvironmentError("%s not found" % (_mysql_config_path,))
    OSError: mysql_config not found

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-txlk8w2u/mysqlclient/

我尝试运行 sudo pip install 和 pip3 install flask-mysqldb 但每次我都收到与上面发布的相同的错误。

我该怎么做才能解决这个问题？

错误信息很清楚：

OSError: mysql_config not found

您需要 mysql_config。使用 apt.

安装 either libmariadbclient-dev or libmysqlclient-dev

然后尝试再次使用 pip，但不是和 sudo。

混合使用系统级 Python 软件包和 pip 安装的软件包是灾难的根源。看起来你的项目已经有一个 virtualenv，所以使用它。如果您在 requirements.txt 文件或 Pipfile.

中指定依赖项，则可获得加分
