我在安装时遇到了一些问题 mysqlclient 在docker中，conatiner帽子是由mysql优化的docker图像制作的( mysql/mysql-server ). 该容器在oracle linux sysrem（centos）上运行。
错误如下所示

我注意到这个问题是因为没有 gcc 在集装箱里。安装后 gcc 与 yum install gcc ，我收到了另一个类似这样的错误

我意识到这是因为 mysql.h 不存在。我发现在这个问题上，我可以检查文件是否存在。然而，似乎 mysql 文件夹在中不存在 /use/local/ 目录。
这就是造成我困惑的原因。有人知道为什么会这样吗？为什么没有一个 mysql.h 当docker映像本身是mysql优化的时候？提前谢谢。

你需要安装 mysql-community-devel ，的 mysql.h 在这个包裹里。
注意：您需要先卸载 mysql-community-server-minimal ，然后重新安装 mysqlclient 安装完成。否则，您将遇到以下冲突：
事务检查错误：安装mysql-community-devel-8.0.13-1.el7.x86\u 64的文件/usr/bin/mysql\u config与包mysql-community-server-minimal-8.0.13-1.el7.x86\u 64的文件冲突
步骤如下：（省略pip安装）

yum remove -y mysql-community-server-minimal
yum install -y gcc
yum install -y mysql-community-devel
pip install mysqlclient
yum remove -y mysql-community-devel
yum install -y mysql-community-server-minimal

mysqlclient install的输出：


# pip install mysqlclient

Collecting mysqlclient
  Using cached https://files.pythonhosted.org/packages/ec/fd/83329b9d3e14f7344d1cb31f128e6dbba70c5975c9e57896815dbb1988ad/mysqlclient-1.3.13.tar.gz
Installing collected packages: mysqlclient
  Running setup.py install for mysqlclient ... done
Successfully installed mysqlclient-1.3.13
You are using pip version 8.1.2, however version 18.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

最后，你的最后一个问题是：
当docker映像本身经过mysql优化时，为什么没有一个mysql.h文件
从dockerhub，你可以找到 mysql/mysqlserver dockerfile，在这里：

FROM oraclelinux:7-slim

ARG MYSQL_SERVER_PACKAGE=mysql-community-server-minimal-8.0.13
ARG MYSQL_SHELL_PACKAGE=mysql-shell-8.0.13

# Install server

RUN yum install -y https://repo.mysql.com/mysql-community-minimal-release-el7.rpm \
      https://repo.mysql.com/mysql-community-release-el7.rpm \
  && yum-config-manager --enable mysql80-server-minimal \
  && yum install -y \
      $MYSQL_SERVER_PACKAGE \
      $MYSQL_SHELL_PACKAGE \
      libpwquality \
  && yum clean all \
  && mkdir /docker-entrypoint-initdb.d

VOLUME /var/lib/mysql

COPY docker-entrypoint.sh /entrypoint.sh
COPY healthcheck.sh /healthcheck.sh
ENTRYPOINT ["/entrypoint.sh"]
HEALTHCHECK CMD /healthcheck.sh
EXPOSE 3306 33060
CMD ["mysqld"]

从上面可以看出，它只是使用了预先编译好的mysql server包，没有编译mysql server的源代码，所以不需要任何修改 mysql.h ，仅在生成源代码时使用。
但是当你安装 mysqlclient 使用pip，如 mysqlclient python包具有 C extension 依赖关系，所以必须使用 gcc 要建造，就需要 mysql.h ，这让你有麻烦了。安装后 mysql.h ，一切正常。
