Renv，无法安装devtools

devtools.

• 预期结果安装devtools :安装

• 结果:参见

下面的错误

我尝试通过renv (在Ubuntu上)在RStudio中安装软件包，以用于我自己的软件包。我执行了Renv ()，除了devtools之外，包将安装。当我试图通过renv：：install ()安装devtools时，我得到以下错误：

If freetype2 libpng libtiff-4 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a freetype2 libpng libtiff-4.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=...'

因此，这导致了以下错误：

• No package 'libtiff-4‘找到了
• ：1:22:致命错误: ft2build.h:没有这样的文件，也没有安装软件包“ragg”失败的错误代码1

我尝试了以下几点：

其他包环境中的

• Installation。这没有起作用，out
• https://techoverflow.net/2019/06/11/how-to-fix-ft2build-h-no-such-file-or-directory/似乎遗漏了ft2build.h头文件

libfreetype。因此，我尝试从tar.gz和CRAN为renv安装libfreetype (这不是自动安装的)。这没有成功。--

我找到了这个链接：https://github.com/numworks/epsilon/issues/592，其中设置了PKG_CONFIG_PATH。但我认为只有通过renv安装libfreetype才能做到这一点。

{:~/path_to_package}$ pkg-config --cflags freetype2-I/usr/include/freetype2 
-I/usr/include/libpng16

{:~/path_to_package}$ pkg-config --libs --cflags libtiff-4Package libtiff-4 was not found in the pkg-config search path.

我是linux的新手，我发现安装R包可能非常令人沮丧，因为(1)有许多linux依赖项需要首先安装，(2)需要永远安装。下面是一个脚本，它安装了在我的系统上安装R时发现的依赖项(Linux 21，Vanessa)。
