Question

我在Fedora 26上运行的Python应用程序在Fedora 27上不起作用。

我收到此错误：

ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory

我在升级到Fedora 26后创建了一个新的virtualenv.mariadb-devel已安装。

这是一种解决方法：在文件的第344行添加unsigned int reconnect;：/ usr / include / mysql / mysql.h。结构应如下所示：

  typedef struct st_mysql {
    NET         net;                    /* Communication parameters */
    void  *unused_0;
    char *host,*user,*passwd,*unix_socket,*server_version,*host_info;
    char *info,*db;
    const struct ma_charset_info_st *charset;      /* character set */
    MYSQL_FIELD *fields;
    MA_MEM_ROOT field_alloc;
    unsigned long long affected_rows;
    unsigned long long insert_id;               /* id if insert on table with NEXTNR */
    unsigned long long extra_info;              /* Used by mysqlshow */
    unsigned long thread_id;            /* Id for connection in server */
    unsigned long packet_length;
    unsigned int port;
    unsigned long client_flag;
    unsigned long server_capabilities;
    unsigned int protocol_version;
    unsigned int field_count;
    unsigned int server_status;
    unsigned int server_language;
    unsigned int warning_count;          /* warning count, added in 4.1 protocol */
    unsigned int reconnect;
    struct st_mysql_options options;
    enum mysql_status status;
    my_bool     free_me;                /* If free in mysql_close */
    my_bool     unused_1;
    char                scramble_buff[20+ 1];
    /* madded after 3.23.58 */
    my_bool       unused_2;
    void          *unused_3, *unused_4, *unused_5, *unused_6;
    LIST          *stmts;
    const struct  st_mariadb_methods *methods;
    void          *thd;
    my_bool       *unbuffered_fetch_owner;
    char          *info_buffer;
    struct st_mariadb_extension *extension;
} MYSQL;

可以通过运行命令来解决问题

sed '/st_mysql_options options;/a unsigned int reconnect;' /usr/include/mysql/mysql.h -i.bkp

尝试使用以下方法重新安装MySQL-python：

sudo python -m pip install --no-binary MySQL-python MySQL-python

无法在Fedora 27上的Python2 virtualenv中使用mysqldb
