無法下載非CRAN軟件包

Question

我想下載https://github.com/AdrianAntico/RemixAutoML但是我得到一個錯誤，包CatBoost（這是RemixAutoML的依賴）錯誤：無法訪問存儲庫的索引https://github.com/catboost/ catboost /樹/主/ catboost / R-包/ SRC / contrib請

所以我試圖從' https://github.com/catboost/catboost/releases/download/v0.6.1.1/catboost-R-Windows-0.6.1.1.tgz '手動下載它，但我得到錯誤：

findpack（package，lib.loc）中出錯：沒有名為'catboost'的包調用： - > findpack執行暫停錯誤：包'catboost'延遲加載失敗*刪除'FilePath'錯誤ip（...）： （從警告轉換）軟件包'C：/Users/jarlan/AppData/Local/Temp/RtmpoJEuqk/file20e059cf378c/catboost_0.6.1.1.tar.gz'的安裝具有非零退出狀態

我不知道該怎么辦。

This is the code I ran 
```{r}

#Code that was part of the instructions for downloading RemixAutoML 
to_install <- c("catboost", "caTools", "data.table", "doParallel", "foreach", "forecast", "ggplot2", "h2o", "itertools", "lubridate", "monreg", "pROC", "RColorBrewer", "recommenderlab", "ROCR", "scatterplot3d", "stringr", "tm", "tsoutliers", "wordcloud", "xgboost", "zoo")
for (i in to_install) {
  message(paste("looking for ", i))
  if(i == "catboost" & !requireNamespace(i)) {
    devtools::install_url('https://github.com/catboost/catboost/releases/download/v0.6.1.1/catboost-R-Windows-0.6.1.1.tgz')
  } else if(i == "h2o" & !requireNamespace(i)) {
    if ("package:h2o" %in% search()) { detach("package:h2o", unload=TRUE) }
    if ("h2o" %in% rownames(installed.packages())) { remove.packages("h2o") }
    pkgs <- c("RCurl","jsonlite")
    for (pkg in pkgs) {
      if (! (pkg %in% rownames(installed.packages()))) { install.packages(pkg) }
    }
    install.packages("h2o", type="source", repos="https://h2o-release.s3.amazonaws.com/h2o/rel-yates/3/R")
  } else if (!requireNamespace(i)) {
    message(paste("     installing", i))
    install.packages(i)
  }
}
#now to install the package
devtools::install_github('AdrianAntico/RemixAutoML', force = TRUE, dependencies = TRUE, upgrade = FALSE)

我遇到了同樣的問題，問題是包catboost我刪除了這個代碼包，你的put和我實現安裝其他包，

        to_install <- c("caTools", "data.table", "doParallel", "foreach", "forecast", "ggplot2", "h2o", "itertools", "lubridate", "monreg", "pROC", "RColorBrewer", "recommenderlab", "ROCR", "scatterplot3d", "stringr", "tm", "tsoutliers", "wordcloud", "xgboost", "zoo")

for (i in to_install) {message(paste("looking for ", i))if(i == "catboost" &
    !requireNamespace(i)) {devtools::install_url('https://github.com/catboost/catboost/releases/download/v0.6.1.1/catboost-R-Windows-0.6.1.1.tgz')
      } else if(i == "h2o" & !requireNamespace(i)) {
        if ("package:h2o" %in% search()) { detach("package:h2o", unload=TRUE) }
        if ("h2o" %in% rownames(installed.packages())) { remove.packages("h2o") }
        pkgs <- c("RCurl","jsonlite")
        for (pkg in pkgs) {
          if (! (pkg %in% rownames(installed.packages()))) { install.packages(pkg) }
        }
        install.packages("h2o", type="source", repos="https://h2o-release.s3.amazonaws.com/h2o/rel-yates/3/R")
      } else if (!requireNamespace(i)) {
        message(paste("     installing", i))
        install.packages(i)
      }
    }

之后你需要手動安裝catboost library(devtools) devtools::install_url('https://github.com/catboost/catboost/releases/download/v0.6.1.1/catboost-R-Windows-0.6.1.1.tgz', args = c("--no-multiarch"))

因此你可以跑

 # Depending on the development state (future versions, etc.) you can install via:
devtools::install_github('AdrianAntico/RemixAutoML', upgrade = FALSE)
devtools::install_github('AdrianAntico/RemixAutoML', upgrade = FALSE, dependencies = FALSE, force = TRUE)

這就是全部，如果你沒有運氣從上面的鏈接安裝catboost嘗試與你發現的其他可能你需要嘗試幾次這是這個過程中更困難的部分。
