Question

我使用Windows 10，在＆＃34; C：\ Program Files \ MySQL \ MySQL Server 5.7＆＃34;下安装了MySQL，在＆＃34; D：\ R \ R-3.3.2＆＃34下安装了R ;，在＆＃34; D：\ Rtools＆＃34;下安装了Rtools，在＆＃34; D：\ RStudio＆＃34;下安装了RStudio。然后我按照以下步骤安装RMySQL包：

1：在我的环境变量中添加了MYSQL_HOME = C：\ Program Files \ MySQL \ MySQL Server 5.7 \。

2：在＆＃34; D：\ R \ R-3.3.2 \ etc＆＃34;下创建了Renviron.site文件。内容：MYSQL_HOME = C：/ Program Files / MySQL / MySQL Server 5.7 /

3：验证我的环境变量下的Path值 - ＆gt;系统变量确实包含：D：\ Rtools \ bin; D：\ Rtools \ mingw_32 \ bin; ...

4：在RStudio上运行install.packages（＆＃34; RMySQL＆＃34;，type =＆＃34; source＆＃34;）。

但我收到以下错误消息：

> install.packages("RMySQL", type = "source")

我看到错误消息说＆＃34; c：/ Rtools / mingw_32 / bin / gcc：not found＆＃34;，这可能是因为我在D盘下安装了RTools。我可以成功安装其他R包（这意味着Rtools可以在R中使用），但我不知道为什么这个安装得到了错误的路径。谁能帮忙解决这个问题？非常感谢！

Answer 1

通过将整个Rtools文件夹复制到C盘来解决此问题。 R可以正确加载RMySQL包，尽管这会占用我系统驱动器的相当大的空间。

无法安装RMySQL包，错误c：/ Rtools / mingw_32 / bin / gcc：找不到
