使用pip将mysqlclient安装到MacOS Bigsur时出错

我尝试过为mysqlclient错误编写的常见解决方案

• 第一次尝试：

  brew安装mysql-connector-c

• 第二次尝试：

  LDFLAGS=-L/usr/local/opt/openssl/lib pip安装mysqlclient

• 第三次尝试：

  brew安装zstd

mysql服务器运行良好。 但是错误并没有被纠正

我收到

clanglinker错误

saying

library not found for-lzstd

    clang -bundle -undefined dynamic_lookup -L/usr/local/opt/readline/lib -L/usr/local/opt/readline/lib -L/Users/user/.asdf/installs/python/3.7.10/lib -L/usr/local/opt/llvm/lib -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -L/usr/local/opt/readline/lib -L/usr/local/opt/readline/lib -L/Users/user/.asdf/installs/python/3.7.10/lib -L/usr/local/opt/llvm/lib -L/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib -L/usr/local/opt/llvm/lib -I/usr/local/opt/llvm/include build/temp.macosx-11.2-x86_64-3.7/MySQLdb/_mysql.o -L/usr/local/Cellar/mysql/8.0.25_1/lib -lmysqlclient -lzstd -lresolv -o build/lib.macosx-11.2-x86_64-3.7/MySQLdb/_mysql.cpython-37m-darwin.so

在我的情况下，我没有sudo访问权限，因此为我的用户安装了brew 检查您的brew是否不在默认位置 执行此操作可检查brew的安装位置

brew --prefix
output: Users/helloWorld/homebrew

使用上面的输出设置ld标志和cpp标志 例如，对于我来说，未找到ssl和zstd LIB，因此我这样做：

export LDFLAGS="-L/Users/helloWorld/homebrew/lib L/Users/helloWorld/homebrew/opt/openssl/lib"

export CPPFLAGS="-I/Users/helloWorld/homebrew/include -I/Users/helloWorld/homebrew/opt/openssl/include" 

然后进行pip安装

pip3 install mysqlclient
