Fail to install package - bioconductor after R update

Hello everyone!

I’m an university student and recently I updated my R to 3.6.0 version.

After the update, I can not install the package called ‘Homo.sapiens’

The photo showing my r problem is attached.

Can anyone help me out pleases?

Thank you so much for reading my question!

You might need this first

install.packages("rtracklayer", dependencies = TRUE)

By the way are you using RStudio? Usually when we use Tools > Install Packages from RStudio menu, it will automatically install dependencies

if (!requireNamespace("BiocManager", quietly = TRUE))

sadly it does not work either :frowning:

Do you have xcode installed in your system? You need it for compiling packages on MacOS

xcode-select --install

Here are some installation instructions


Yes! I did get Xcode installed. But it doesn't fix my problem.. :frowning:

Even I have the Xcode, it tells me to install the "rtracklayer"

but either of them is working:

You are having problems compiling the rtracklayer package, you can install the binary version answering "No" when you see this question "Do you want to install from source the package which needs compilation? (Yes/no/cancel)"

You should see this question after running


OMG!!! that fixed my problem!!!!

thank you so much!!!
