尝试使用 ROracle 时，我收到以下错误消息

>   library("ROracle")
Error: package or namespace load failed for ‘ROracle’:
package ‘ROracle’ was installed before R 4.0.0: please re-install it

我已经安装/下载了 DBI、RTools、oracle isntant 客户端（basic + sdk）并尝试按照这些说明进行操作，但没有成功：ROracle install

我可以很好地下载 ROracle（见下文），所以我对缺少的东西感到困惑。我需要降级版本吗？

>   Roracle_path <- "filepath.../ROracle_1.3-2.zip"
>   install.packages(Roracle_path, repos = NULL)

如果您从SOURCES安装软件包，为 R 3.6.x 构建的 ROracle_1.3-2.tar.gz 也适用于 R 4.x。

首先，在 Linux 系统上，您必须安装 Oracle Instant Client basic 和 SDK：

/home/jovyan/R
unzip instantclient-basic-linux.x64-21.4.0.0.0dbru.zip -d /opt/oracle/

unzip instantclient-sdk-linux.x64-21.4.0.0.0dbru.zip -d /opt/oracle

linux 软件包 libaio1 必须安装在系统上：

apt install -y libaio1

接下来，必须设置环境变量：

export PATH="$PATH:/opt/oracle/instantclient_21_4"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/oracle/instantclient_21_4"

最后，可以从 Sources 安装软件包（使用 ROracle_1.3-2.tar.gz (sources) 但不是 ROracle_1.3-2_R_x86_64-linux-gnu.tar.gz (binary) ）：

R CMD INSTALL --configure-args='--with-oci-lib=/opt/oracle/instantclient_21_4/ --with-oci-inc=/opt/oracle/instantclient_21_4/sdk/include' ROracle_1.3-2.tar.gz

在安装过程中，您将看到该软件包将从 SOURCES 安装：

 * installing *source* package ‘ROracle’ ...

检查输出中的行以查看它将从 Sources 安装：

我降级到 R 3.6.3 并使用 RTools 35，现在它可以工作了。
