Hi guys,
my google research didn't bring up any usefull results and at this point I don't know what I could try anymore. I am trying to install devtools, in the following setup:
- Ubuntu 20.04 (Virtualboax)
-
R.version.string
= "R version 3.6.3 (2020-02-29)" - New installation of RStudio (Version 1.2.5042)
I tried to google the specific error ("Error: .onLoad failed in loadNamespace() for 'pkgload', details:"). I found this one link on which the legendary hadley wickham suggested updating the rlang package. Which I did. However it didn't fix the issue.
Has anybody any idea?
I also installed the necessary system dependenvies. However I just got those after I already started the install.packages("devtools")
sudo apt-get install build-essential libcurl4-gnutls-dev libxml2-dev libssl-dev
> install.packages("devtools")
