在更新到最新版本后结束：我的Ubuntu 16.04LTS更新/升级，我的R版本，我的Rstudio服务器版本，我的libicu-dev版本，验证了anaconda提供我的python而不是我的R语言。还有什么可以帮到你？这个stringi包也可能是我的新问题的根源（之前没有问题）无法创建r markdown文档（看起来像Knittr使用stringi），jupyter笔记本使用R语言，无法安装ggplot2等等。
g ++已经是最新版本（4：5.3.1-1ubuntu1）
libicu-dev已经是最新版本（55.1-7ubuntu0.2）

还有其他一些诊断要尝试吗？ BTW stringi在R3.3中运行良好，但现在我有R3.4。
答案 0 :(得分：1)
此错误：
Error: package or namespace load failed for ‘stringi’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/ga/R/x86_64-pc-linux-gnu-library/3.4/stringi/libs/stringi.so':

表示未找到所需的符号。 c++filt通过对符号进行解码来帮助我们：
$ c++filt _ZTIN6icu_558ByteSinkE
typeinfo for icu_55::ByteSink
这可能意味着安装期间stringi使用的ICU库（版本55）不提供此符号。
对于它的价值，使用当前的Ubuntu 16.04，安装工作正常。这是我的配置输出：

我能看到的唯一区别是，就我而言，我正在使用g++ -std=c++0x;你似乎在使用g++ -std=gnu++11。我想知道这可能是原因吗？我也想知道为什么stringi在这里使用g++而非g++-5;如果您设置了不同的默认编译器，那可能就是原因。
