我试图安装错误gem install libv8 -v'3.16.14.7'中的最后一个建议命令 但是另一个错误安装libv8错误错误：无法构建gem原生扩展

Answer 1

如之前评论中所述，-- --with-system-v8后缀使捆绑成功：

gem install libv8 -v '3.16.14.7' -- --with-system-v8

Answer 2

首先添加gem gem'libv8'，'〜＆gt; 3.16'，'＆gt; = 3.16.14.7'进入gem文件或运行 gem install libv8 -v 3.16.14.7 。

安装或添加gen后，运行捆绑安装。

将成功添加gem文件。

Answer 3

运行

gem install httparty -v '0.13.7'

然后运行

bundle install
