Question

我正在帮助这个rails项目。（我刚刚开始编写ruby，甚至编程，所以请放轻松我...）当我尝试使用项目共享的Gemfile / Gemfile.lock进行bundle install时，会导致json 1.8.1和libv8 3.16.14.3安装时出现问题。

我点击了一些搜索结果，其中一半的答案涉及bundle update，根据团队成员的更多经验，这是团队工作时的一个禁忌，因为它会给项目Gemfile.lock带来混乱。

我尝试了另一半与El-Captain相关的恢复模式位或gem update -system或libv8相关的东西。似乎任何一个都没有用。

然后，我很可能没有使用精确的查询来搜索答案，因为我是初学者并且没有太多的知识或猜测通常导致问题的原因或'这是基础库所以我应该做得好。'或类似的东西。

如果有人可以帮助我，那将是非常善良的。我要把这个日志留在这里：

我很抱歉，我正在使用Mac！

Answer 1

首先删除Gemfile.lock文件，然后删除

bundle install

Answer 2

我找到了这个失败的原因，这是那些宝石版本和ruby版本的兼容性。

我非常清楚这可能是一个问题，但我认为我确保为Gemfile / Gemfile.lock中指定的gems版本设置了正确的ruby版本。我想念的是rbenv错误配置的痕迹，显示为＆lt; 2.3.0＆＃39;在日志中。我认为它应该是＆＃39; 2.0.0＆＃39;。

由于我没有做好rbenv设置，因此bundler指的是不在项目目录中的ruby。因此明显的版本不兼容。

Answer 3

错误：无法构建gem原生扩展。

这可能是因为您没有安装node.js：

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - sudo apt-get install -y nodejs

Answer 4

试试这个：

sudo apt-get install nodejs

Answer 5

我遇到了类似的问题，除了我，我只得到一个与json gem相关的错误（相同的版本号和所有内容）。我发现this solution并且它对我有用（我不得不首先删除Gemfile.lock）。希望它可以帮到你一点！
