Answer 1

Sonunda sorunu düzeltildi:

sudo apt-get install libxml2-dev 

Sonra başka problemler açıldı: Sadece

install.packages("curl") 

Answer 2

Sen: bukle paketini yükleyerek çözülebilir

Error : object ‘curl_fetch_memory’ is not exported by 'namespace:curl' 

R (R sürüm 3.2.1)

'un en yeni sürümüne güncellenmesi gerekiyor

Answer 3

Bazı geliştirici kitaplıkları (kaynakları) gerektirir: curl developer, xml2 developer bağımlı olarak. , bu nedenle paket deposuna (yum, dnf, apt-get) yükleyin ve devtools paketini yeniden yüklemek için yeniden deneyin.
