我正在尝试使用安装 RMySQL 包

bash > R
...
> install.packages('RMySQL', repos='http://cran.us.r-project.org')

并在最后得到以下错误输出：

任何想法？

您需要提供有关安装的更多详细信息。我猜你正在使用 R 的自制版本？强烈建议您改用mac 的官方 R 包，这是 CRAN 构建服务器（和大多数用户）正在使用的。

libmysqlclient也就是说，您的安装似乎有些奇怪。假设这是 brew，请尝试重新安装：

brew remove mysql-connector-c
brew upgrade
brew install mysql-connector-c

验证是否libmysqlclient.18.dylib已安装：

ls /usr/local/opt/mysql-connector-c/lib

或者，您可以尝试链接到 mariadb：

brew remove mysql-connector-c
brew install mariadb

如果这不起作用，则可能是 R 的 brew 版本中的错误。编译器无法记录libmysqlclient.18.dylib. 也许 R 没有将正确的RPATH标志传递给链接器。
