ROracle LoadLibrary 失敗：找不到指定的模塊

Question

在過去的幾天里，我一直試圖在我的 Win 10 VM 上安裝 ROracle，但我嘗試過的任何方法都不起作用。 當前安裝的工具和軟件是：

R 4.1.3

RStudio 2022.02.0+443 RTools 4.0.1.0

即時客戶端_12_1

DBI

到目前為止我嘗試過的事情：

通過 CRAN 安裝 - 使用內置安裝程序安裝到我的庫位置。 編輯 OCI_LIB64 和 PATH 以包含即時客戶端位置。 Rprofile.site 文件已更新為指向庫位置。

手動下載 ROracle zip 文件並手動移動到庫位置。 只能對舊版本的 ROracle 執行此操作，因為我無法找到最新版本 (1.3-1.1) 的 zip 文件。

已嘗試使用舊版本的 R3.6.3 和 RTools35 進行上述操作。

加載時一切都失敗了。 我不知道還能做什么...下面是我嘗試通過 CRAN 安裝所有最新軟件版本時看到的內容。

通過將 Instantclient 升級到最新版本並將 P:\Oracle\OPT\instantclient_21_3\sdk\include 中每個文件的權限更改為 unblocked 解決了該問題。 重新運行安裝程序向導並將其安裝到標准位置（不是我正在使用的網絡共享）並且它通過了。 用一些時間檢查代碼對其進行了測試，一切正常。 希望感謝 ROracle 軟件包安裝失敗以及用戶 obrl_soil 和 Eric Moffett 鼓勵我更改所有文件設置。
