无法安装flextable

Question

我在安装Flextable时遇到了问题，这似乎是由于gdtools包的原因。看起来gdtools依赖于.dylib文件？有什么想法吗？

> install.packages("flextable")

  There is a binary version available but the source version is later:
          binary source needs_compilation
flextable  0.4.0  0.4.2             FALSE

installing the source package ‘flextable’

我设法通过重装quartz解决了这个问题：https://www.xquartz.org

Answer 2

适用于mac用户。这有时会发生在mac os x的更新上。这需要Homebrew(可以使用以下命令进行安装：

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

1. 关闭所有R会话(不是强制性的，但从经验来看，这是最佳解决方案)。

在终端中，运行以下命令：

brew update
brew upgrade
brew reinstall cairo

1. 打开R会话并运行以下代码：

install.packages("gdtools"，=“”)来源

我会尽力帮助你，即使我不知道你的操作系统是Ubuntu 20.10，我也是这样解决的(这个解决方案适用于Debian、Ubuntu等)：

在终端中键入：sudo apt-get install libfontconfig1-dev

然后：sudo apt-get install libcairo2-dev

在R控制台中键入：

install.packages("flextable")库(Flextable)

其他发行版，根据您的发行版进行安装：

步骤1

• deb: libfontconfig1-dev (Debian、Ubuntu等)
• rpm: fontconfig-devel (Fedora、EPEL)
• csw: fontconfig_dev fontconfig freetype (OSX)

步骤2

• deb: libcairo2-dev (Debian，Ubuntu)
• rpm: cairo-devel (Fedora，CentOS，RHEL)
• csw: libcairo_dev libcairo2-dev (OSX)
