Error: package or namespace load failed for ‘haven’ in dyn.load(file, DLLpath = DLLpath, …):

[tidyx]

I am not able to open install the 'haven' packages. It gives me the following error:

*** copying figures
** building package indices
** installing vignettes
** testing if installed package can be loaded
Error: package or namespace load failed for ‘haven’ in dyn.load(file, DLLpath = DLLpath, ...):

Warning in install.packages :

The downloaded source packages are in

I have also tried to remove and re-install it, but without success.

install.packages('haven', dep = TRUE)

Try specifying the repository. Sometimes install.packages cannot find the right repository.

For people who googled to here, you may try this:
withr::with_makevars(c(PKG_LIBS = "-liconv"), install.packages("haven"), assignment = "+=")
It seems someone create a typo in somewhere.

Thank MajoroMask!
very useful information!

[inesHellmann]

Thanx a MajorMask! This was driving me crazy.

[sgmccalla]

Thank you @MajoroMask! I was able to install haven finally.

[yangkl0909]

Thank you @MajoroMask! Very useful suggestion.

[marcora]

Why is this issue closed? I specify the right repository and I still have the same problem!
Doing what MajoroMask suggested fixes the issue temporarily, but this is hardly resolved!

[hadley]

Because I didn’t know it was a problem — generally comments on closed issues go unread.

I hit the same error with the readxl package after resolving the haven one with @MajoroMask's solution. Applying the same to readxl worked:
withr::with_makevars(c(PKG_LIBS = "-liconv"), install.packages("readxl"), assignment = "+=")

I installed tidyverse via conda.

[arinbasu]

I had the same problem, I solved it by removing haven and reinstalling tidyverse.
Now it works (fingers crossed).
So I did:
conda remove r-haven
conda will remove haven but will also ask to remove r-essentials and r-tidyverse
Remove these as well.
Then re-install tidyverse, with
conda install r-tidyverse
(This time do not specify conda-forge, do not use the option -c conda-forge)
A newer version of haven will be installed and this solved my problem.

[hadley]

If you use conda, you must use conda to install everything else. You can not mix install.packages() and conda install

[aakhmetz]

I mix conda install and install.packages() quite a lot, and there is no problem. @MaxGhenis solution worked for me

[inesHellmann]

I just updated all packages on R 3.6.0 on our centos server -- just R, no conda. When installing haven and readxl, I am still getting the same error message as a year ago: undefined symbol: libiconv
which can be fixed by the MajoroMask suggestion.
