Я пытаюсь вытащить некоторые данные json с удаленного сервера, используя fromJSON
:
> server <- 'http://111.111.000.00:3000'
> streams <- fromJSON(paste(server, '/output/streams', sep=""), flatten=TRUE)
Результат:
Error: Required package curl not found.
Please run: install.packages('curl')
Поэтому я попытался установить его:
> install.packages("curl")

Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
* rpm: libcurl-devel (Fedora, CentOS, RHEL)
* csw: libcurl_dev (Solaris)
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=...'

Зачем? Что происходит не так? Как я могу это исправить?
Это было нормально, когда я был на Xubuntu 16.04. Но теперь я на Kubuntu 16.10.
Есть идеи?
