我尝试过为 mysqlclient 错误编写的常见解决方案

• 第一次尝试：brew install mysql-connector-c
• 第二次尝试： LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient
• 第三次尝试：brew install zstd

并且mysql服务器运行良好。但错误尚未修复..

我越来越clang linker error想说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

我正在使用 asyncio.gather，并在出现异常时尝试重试。但它无法重试，并出现如下错误。我应该如何修复它以重试？

11 -- RETRY Server disconnected without sending a response.
11 -- RETRY cannot reuse already awaited coroutine
11 -- RETRY cannot reuse already awaited coroutine

我的代码：

        for i in range((len(tasks) // TASK_CHUNK_SIZE) + 1):
            while True:
                try:
                    res = await asyncio.gather(*tasks[TASK_CHUNK_SIZE * i:TASK_CHUNK_SIZE * (i + 1)])
                    for rows in res:
                        f.writelines([f'{row}\n' for row in rows])
                    await asyncio.sleep(1)
                    break
                except Exception as e:
                    print(f'{(i + 1) * TASK_CHUNK_SIZE} -- RETRY {e}')

                    await asyncio.sleep(10)
                    continue
