關注一些帖子並安裝完畢

brew install mysql-connector-c

但仍然面臨着這個問題。

對於其他解決方案嘗試以下解決方案

但找不到/ usr / local / bin / mysql / bin / mysql_config

我在MacOS上運行，對於Mysql，我安裝了XAMPP。

Answer 1

對於mac上的python3 + mysql。 這對我有用：

1. brew install mysql-connector-c
2. 編輯mysql_config（找到它： which mysql_config ）

在mysql_config中更改以下內容：

# Create options 
libs="-L$pkglibdir"
libs="$libs -l "

至：

# Create options 
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

3. brew info openssl

4. 最后pip3 install mysqlclient

Answer 2

在XAMPP中，mysql_config將位於以下路徑中的某個位置。 （根據你安裝的地方）

/Applications/XAMPP/xamppfiles/bin/mysql_config

更新$ PATH以包含bin路徑

export PATH=$PATH:/Applications/XAMPP/xamppfiles/bin/

運行mysql_config， - --libs和--libs_r應該有-lmysqlclient -lssl -lcrypto ，

 <XAMPP_PATH>mysql_config | grep libs
        --libs           [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqlclient -lssl -lcrypto]
        --libs_r         [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqlclient -lssl -lcrypto]
        --libmysqld-libs [-L/usr/local/Cellar/mysql/5.7.21/lib -lmysqld -lssl -lcrypto]

如果沒有，請將mysql_config更新為以下值。

libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

然后運行

pip3 install mysqlclient
