My builds started failing recently. I have `devtools` in my `r_packages` list. The build tries to install `devtools`, which depends on `usethis`, which depends on `gert`, which fails to install:
```
* installing *source* package ‘gert’ ...
** package ‘gert’ successfully unpacked and MD5 sums checked
** using staged installation
Using PKG_CFLAGS=
Using PKG_LIBS=-lgit2
----------------------------- ANTICONF -------------------------------
Configuration failed to find libgit2 library. Try installing:
* brew: libgit2 (MacOS)
* deb: libgit2-dev (Debian, Ubuntu, etc)
* rpm: libgit2-devel (Fedora, CentOS, RHEL)
If libgit2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libgit2.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
-------------------------- [ERROR MESSAGE] ---------------------------
:1:18: fatal error: git2.h: No such file or directory
compilation terminated.
----------------------------------------------------------------------
ERROR: configuration failed for package ‘gert’
```
I have a simple config:
```
language: r
cache: packages
warnings_are_errors: false
r:
- bioc-release
- oldrel
- release
- devel
r_packages:
- covr
- devtools
- tidyverse
- shiny
after_success:
- Rscript -e 'library(covr); codecov()'
```
This is a fairly common package, but this does not seem to be a widespread problem. Why is this error happening for me?

If you’re linking against a C library, you need to [install its development Apt package](https://docs.travis-ci.com/user/languages/r/#apt-packages):
```auto
addons:
apt:
packages:
- libgit2-dev
```

That makes sense, but I didn’t have to do that before and it doesn’t seem like other packages that you use devtools do that that either.

Maybe before, it happened to be preinstalled. [In other topics](https://travis-ci.community/search?q=apt%20packages%20category%3A51), you can see plenty of cases where people install Apt development packages.

Hi,
I also have the same issue when using R studio on Mac OS to install package “stopwords”, and the error message is exactly the same.
I’m not sure how to resolve it from reading this post, as I have no idea about R configuration and environment…

@jeroen and @jimhester
I have a similar problem with a package ([github.com/rmsharp/nprcgenekeepr](http://github.com/rmsharp/nprcgenekeepr)) that used to build. I first got the following errors:
- installing _source_ package ‘textshaping’ …
\*\* package ‘textshaping’ successfully unpacked and MD5 sums checked
\*\* using staged installation
Package harfbuzz was not found in the pkg-config search path.
Perhaps you should add the directory containing `harfbuzz.pc' to the PKG_CONFIG_PATH environment variable No package 'harfbuzz' found Package fribidi was not found in the pkg-config search path. Perhaps you should add the directory containing `fribidi.pc’
to the PKG\_CONFIG\_PATH environment variable
No package ‘fribidi’ found
Based on my limited understanding I added the following to my .travis.yml file.
addons:
apt:
packages:
- harfbuzz
- fribidi
This did not work and produced the following error message:
Reading state information…
E: Unable to locate package harfbuzz
E: Unable to locate package fribidi
apt-get.diagnostics
apt-get install failed
Explanations and suggests are most welcome.

You can try adding this to your .travis.yml
```auto
addons:
apt:
packages:
- libharfbuzz-dev
- libfribidi-dev
```

Worked perfectly. Thank you.
Now to get the Apple build to work
