mysql - `brew link mysql` 给出“错误：无法符号链接 bin/my_print_defaults”

Question

brew install mysql-connector-c

给了：

Error: Cannot install mysql-connector-c because conflicting formulae are installed.

  mysql: because both install MySQL client libraries

Please `brew unlink mysql` before continuing.

所以：

brew unlink mysql
Unlinking /usr/local/Cellar/mysql/5.7.9... 88 symlinks removed

brew install mysql-connector-c

工作正常。但现在brew link mysql给出：

Linking /usr/local/Cellar/mysql/5.7.9... 
Error: Could not symlink bin/my_print_defaults
Target /usr/local/bin/my_print_defaults
is a symlink belonging to mysql-connector-c. You can unlink it:
  brew unlink mysql-connector-c

To force the link and overwrite all conflicting files:
  brew link --overwrite mysql

To list all files that would be deleted:
  brew link --overwrite --dry-run mysql

使困惑。取消链接？覆盖？

我陷入了同样的境地。我解决了如下问题。

$ ls /usr/local/Cellar/mysql*
/usr/local/Cellar/mysql:
5.7.19

/usr/local/Cellar/mysql-connector-c:
6.1.11

$ brew unlink mysql
Unlinking /usr/local/Cellar/mysql/5.7.19... 0 symlinks removed

$ brew link --force mysql-connector-c
Warning: Already linked: /usr/local/Cellar/mysql-connector-c/6.1.11
To relink: brew unlink mysql-connector-c && brew link mysql-connector-c

$ brew unlink mysql-connector-c

$ brew link mysql-connector-c
