當我打開 R 時，在我輸入任何命令之前，控制臺會立即顯示一個錯誤，表明該curatedMetagenomicData軟體包未安裝。

curatedMetagenomicData是我幾年前使用的 Bioconductor 包裝，我一定在某個時候將其移除。當我嘗試重新安裝它時，安裝失敗，似乎是因為它尚未安裝？

這似乎會在意想不到的地方引起問題，例如當我嘗試編織 R Markdown 檔案（與 完全無關curatedMetagenomicData）時，該檔案在 RStudio 的“渲染”視窗中失敗并顯示以下訊息。
Error in library("curatedMetagenomicData") :
there is no package called 'curatedMetagenomicData'

我已嘗試盡可能徹底地洗掉我的 R 和 RStudio 安裝，然后重新安裝，但問題仍然存在。我不明白是什么提示 R 檢查是否安裝了這個包。誰能幫我理解這一點？我目前不需要使用有問題的包，但錯誤變得很痛苦。
編輯：
當我嘗試從源代碼安裝任何軟體包（無論是其他軟體包curatedMetagenomicData，例如dbplyr）時，也會出現此問題。在每種情況下，問題顯然是尚未安裝 curatedMetagenomicData。

uj5u.com熱心網友回復：
根據評論中的回復，我會將我的評論提升為答案。
此問題的兩個可能原因是
- 您的主目錄中有一個
.Rprofile檔案正在嘗試加載包 - 您當前的作業目錄中有一個
.RData正在自動加載的檔案；它里面有一個物件會觸發這個包的加載
請注意，在任何一種情況下，名稱以 a 開頭的檔案.通常默認情況下在檔案管理器/檔案串列中是不可見的，因此您可能需要仔細搜索它們
file.exists(".RData")并file.exists("~/.Rprofile")會告訴你這些檔案是否存在；您可以通過臨時移動/重命名每個問題來診斷問題。
