尝试在 Ubuntu 18.04 上安装 Mysql 8 时出现 Dkpg 错误

我正在尝试在 AWS Ubuntu 18.04 实例上安装 mysql 8。

按照说明，我做了：

wget –c https://dev.mysql.com/get/mysql-apt-config_0.8.13-1_all.deb

答复是：

然后我做了：

sudo dpkg –i mysql-apt-config_0.8.13-1_all.deb

答复是：

dpkg: error: need an action option

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !

有任何想法吗？

请小心从某处复制命令。

您有印刷错误“ –”（破折号, 0xe2 0x80 0x93)，但你应该有简单的减号“ -”(连字符减号，0x2d）。

您需要将命令修复为：

wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.13-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb

如果您正在遵循来自受尊敬来源的一些官方指南 - 那么请告诉其作者使用正确的符号。

如果您不确定命令语法 - 请参阅手册页：

  1. man wget本地或在线的
  2. man dpkg本地或在线的
