    我正在尝试使用python 3在OSX high sierra上的virtrualenv中安装mysqlclient。并得到以下错误:

    尝试 xcode-select --install 但没有起作用。我已经在同一台计算机上安装了mysql服务器。

    在升级到osx Mojave和python 3.7.2之后,我也遇到了同样的问题。这就是我的工作原理:

    # Required for mysqlclient, see brew info openssl
    echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
    export LDFLAGS="-L/usr/local/opt/openssl/lib"
    export CPPFLAGS="-I/usr/local/opt/openssl/include"
    
    pip3 install mysqlclient
    

    希望有帮助。更多信息请参见 here .

    如果你有openssl@1.1,您将遇到错误,因为 mysqlclient 使用 /usr/local/opt/openssl 你的目录里没有这个。因此,使用名称创建一个符号链接 openssl 指向 openssl@1.1 .

    这个shell命令对我有效-

    ln -s /usr/local/opt/openssl@1.1 /usr/local/opt/openssl

    幸亏 radtek's answer ,我仅使用此命令解决了此问题:

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

    要使其也适用于未来的终端会话,请执行以下操作:

    echo 'export LDFLAGS="-L/usr/local/opt/openssl/lib"' >> ~/.zshrc
