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：

  Failed building wheel for mysqlclient

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

回答：

升级到osx Mojave和python 3.7.2后，我遇到了同样的问题。这对我有用：

# 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

希望能帮助到你。有关更多信息，请参见此处。
