特殊的安装警告，导致包装发生故障

本文介绍了特殊的安装警告，导致包装发生故障的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我要按照说明在R中安装xgboost软件包:

I want to install the package xgboost in R as per the instructions:

install.packages("drat", repos="https://cran.rstudio.com")
drat:::addRepo("dmlc")
install.packages("xgboost", repos="http://dmlc.ml/drat/", type = "source")

前两个软件包的安装似乎工作正常:

The installation of the first two packages seems to work fine:

install.packages("drat", repos="https://cran.rstudio.com")
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0  0 49369    0     0    0     0      0      0 --:--:--  0:00:01 --:--:--     0100 49369  100 49369    0     0  40981      0  0:00:01  0:00:01 --:--:-- 41004

The downloaded binary packages are in
    /var/folders/sx/c5z57jp103s493xxcn9bhvwc0000gn/T//RtmpluolUL/downloaded_packages

drat:::addRepo("dmlc")

但是xgboost的最终安装确实是不规则的，我无法在上一篇文章中找到错误:

But the final installation of xgboost is really irregular and I couldn't fid the error in a previous post:

% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

The downloaded source packages are in
    ‘/private/var/folders/sx/c5z57jp103s493xxcn9bhvwc0000gn/T/RtmpluolUL/downloaded_packages’

该软件包无法正确下载，因此，当我尝试在数据集上运行xgboost时，会出现以下错误:

The package does not download properly and hence it gives the following error when I try to run xgboost on a dataset:

Error in xgb.DMatrix(data, label = label, missing = missing) :
  [14:53:26] amalgamation/../dmlc-core/src/io/local_filesys.cc:61: LocalFileSystem.GetPathInfo 201-225 Error:No such file or directory

推荐答案

根据这篇文章，当您看到此错误时，应仔细检查是否已向xgb.DMatrix函数提供了所有数字类型功能".为我解决了这个问题.

According to this post, you should "double check if you have provided all numeric type features to xgb.DMatrix function" when you see this error. Solved the issue for me.
