我正在尝试使用fromJSON
从远程服务器中提取一些json数据:
> server <- 'http://111.111.000.00:3000'
> streams <- fromJSON(paste(server, '/output/streams', sep=""), flatten=TRUE)
结果:
Error: Required package curl not found.
Please run: install.packages('curl')
所以我尝试安装它:
> install.packages("curl")

If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

为什么呢?出了什么问题?我该如何解决?
当我在Xubuntu 16.04上时,没关系。但现在我在Kubuntu 16.10上。
有什么想法吗?

libcurl4-openssl-dev
不是R包,而是Linux库。
在控制台类型中:
sudo apt-get install libcurl4-openssl-dev
注意:您需要 sudo 电源。

尽管已经安装了libcurl4-openssl-dev
apt
软件包,但我在Ubuntu Server 18.04上遇到了此错误。我不得不查找where the package installs libcurl.pc
来找出要使用的命令:
wget <curl-package-address>
R CMD INSTALL --configure-vars='LIB_DIR=/usr/lib/x86_64-linux-gnu/pkgconfig' <curl-file.gz>
(检查“ ANTICONF ERROR”上方的消息以下载和安装正确的文件。对于发问者,它是https://cran.rstudio.com/src/contrib/curl_2.3.tar.gz
;我的是https://cloud.r-project.org/src/contrib/curl_4.3.tar.gz
。)

我在 Fedora Workstation 33 中安装 R 包时遇到了这个问题。按照提示,确保为适当的架构安装 libcurl-devel
,在本例中为 libcurl-devel.x86_64
:
sudo dnf install openssl-dev libcurl-devel.x86_64

就我的Ubuntu 18而言,这些解决方案都无法在Rstudio中使用。
当我最终决定从命令行运行R时,成功-我无法告诉您哪个“解决方案”是关键,因为到目前为止,我已经尝试了所有这些解决方案。
请注意,如果我再次尝试运行Rstudio,则任何安装尝试仍将失败。
因此,Rstudio可能无法正确推断环境。

刚刚在使用 GitHub 操作按 cron 计划运行 R 脚本时遇到了这个问题。
在 R 文件中将 sudo apt-get install libcurl4-openssl-dev
弹出到 system() 中有效。比单独在运行器上设置 bash 命令要容易得多。
system("sudo apt-get install libcurl4-openssl-dev")
