Question

我尝试在R Studio中安装两个软件包：tidyverse和quantmod。然而，两者都给我错误，我无法理解为什么（谷歌搜索没有帮助理解问题）。

对于整洁的经文，我得到：

> install.packages("tidyverse")
also installing the dependency ‘xml2’


  There are binary versions available but the source versions are later:
          binary source needs_compilation
xml2       1.1.1  1.2.0              TRUE
tidyverse  1.1.1  1.2.1             FALSE

Do you want to install from sources the package which needs compilation?
y/n: y
installing the source packages ‘xml2’, ‘tidyverse’

对于quantmod，我也有两个错误：

我认为这可能与我的道路有关，但我没有足够的经验让它发挥作用。

Answer 1

通过卸载我通过Homebrew安装的所有R版本来解决这个问题：

JSON.stringify(['Boxer', 'Terrier']) === JSON.stringify(['Boxer', 'Terrier']);

然后从CRAN here重新安装。

Answer 2

我遇到了同样的问题。我终于通过参考here

解决了这个问题

首先，按照libxml2 web的说明手动安装lxml2，但是在安装时出现错误：

...
mkdir: /usr/include: Operation not permitted
...

然后将前缀更改为：

./configure --prefix=/usr/local --disable-static --with-history && make
sudo make install

然后再次安装R包“ xml2”，确定。
