Question

在运行捆绑软件安装时，出现以下错误。因此，找到配置文件不是问题-它知道它在哪里...只是不执行它。我确实安装了xcode。我检查了多个问题，很多问题都表明我明确指出了配置文件的位置，但这本身并不是我的问题。有什么想法吗？

我从事的每一项工作，我都可能会处理这种胡说八道。有时，根据您的系统设置方式，您可能会在路径中使用多个版本，或者默认情况下可能显示错误的版本。不管怎么说，这通常意味着存在lib或bin路径问题。

尝试首先使用此方法安装它（不使用sudo，如果失败，则使用sudo），然后运行bundle。实际上可能会失败，因为gem没有安装扩展的权限。

sudo gem install mysql -- —–with-mysql-config=/usr/local/bin/mysql_config

来自this other post

如果仍然失败，那么您可以发布以下内容：

echo $PATH和echo $DYLD_LIBRARY_PATH

（编辑：我认为我的mysql路径错误，但是请确保您没有多个路径。能否验证/ usr / local / mysql / bin / mysql_config也不存在？）

无法在/ usr / local / bin / mysql_config执行mysql_config
