Problem installing package "igraph"

I can't install the igraph package. I've already tried a lot of things but it is still not working...
I am using Windows 10, R Studio 1.2.5033 and R 3.6.3
Here is the error message :

make: *** [C:/PROGRA~1/R/R-36~1.3/etc/i386/Makeconf:208: feedback_arc_set.o] Error 1
ERROR: compilation failed for package 'igraph'

  • removing 'C:/Users/Namow/Documents/R/win-library/3.6/igraph'
    Warning in install.packages :
    installation of package ‘igraph’ had non-zero exit status

I have seen exactly the same problems. Waiting for authors to correct it somehow. Something is wrong with compilation from sources as previous version installs without any issues.

Welcome @namow and @Andrzej.

An alternative is to install the binary version of the package (if they are available for your OS). In your case, you can try the following in the console:

install.packages("igraph", type = "binary")

Using type = "binary" may give you a slightly older version of the package, but most of the time, that should not cause too many problems.

I have tried something else (idea from this link


But again it did not work and I had this message

Erreur : Failed to install 'cytofkit' from GitHub:
  (converti depuis l'avis) installation of package ‘igraph’ had non-zero exit status

Hi @namow,
Do you really need the newest version of igraph package ?
The newest version is 1.2.5, the previous version is
Installing causes no problems.
So with:


when you see this;

click "No", and you are good to go.
This works for me on Windows 10 x64, R 3.6.2, RStudio v. 1.4.84.
Please let us know the result ?
Best regards.

Hi Andrzej thanks for your answer.
I ve' found this answer here :
Maybe you can help and tell me what to do step by step ? Sorry I am a beginner...

I just had a quick peek at the Github page and that does not look like the suggested way to install the cytofkit2 package. What happens if you follow this part?

Hi clausp !

Thank you for your answer ! It worked for me I had this :

install.packages("igraph", type = "binary")
Installing package into ‘C:/Users/Namow/Documents/R/win-library/3.6’
(as ‘lib’ is unspecified)

There is a binary version available (and will be installed)
but the source version is later:
binary source
igraph 1.2.5

essai de l'URL ''
Content type 'application/zip' length 9157807 bytes (8.7 MB)
downloaded 8.7 MB

package ‘igraph’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in

But I needed the igraph package to install cytofkit2 with this command :

> devtools::install_github("JinmiaoChenLab/cytofkit2")

Unfortunately I have still the problem with igraph :

Erreur : Failed to install 'cytofkit2' from GitHub:**
Failed to install 'FlowSOM' from Bioc:**
(converti depuis l'avis) installation of package ‘igraph’ had non-zero exit status

Here is what's happened
