捆绑安装不成功

Question

我目前正在帮助这个 Rails 项目。 （我刚开始 ruby​​，甚至编程，所以请放轻松...） 当我尝试bundle install 与项目共享Gemfile/Gemfile.lock 时，它会引起json 1.8.1 和libv8 3.16.14.3 安装的一些麻烦。

我点击了一些搜索结果，其中一半的答案涉及bundle update，根据经验丰富的团队成员，这是在团队中工作时的禁忌，因为它会给项目 Gemfile.lock 带来混乱。

我用不同的东西尝试了另一半，比如 El-Captain 相关的恢复模式位或gem update -system 或 libv8 相关的东西。 似乎其中任何一个都不起作用。

再说一次，我很有可能没有使用精确的查询来搜索答案，因为我是初学者，对通常导致问题的原因或“这是基础库所以我应该”没有太多的知识或猜测把这件事做好。或类似的东西。

如果有人能帮助我，那将是莫大的善意。 我将把日志留在这里：

对不起各位，我用的是 Mac！

Answer 1

我找到了这个失败的原因，是那些gem的版本和ruby版本的兼容性。

我非常清楚这可能是个问题，但我想我确保我为 Gemfile/Gemfile.lock 中指定的 gem 版本设置了正确的 ruby​​ 版本。我错过的是rbenv配置错误的痕迹，在日志中显示为“2.3.0”。我认为应该是“2.0.0”。

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

Answer 2

先删除你的Gemfile.lock文件，然后

bundle install

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：

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

Answer 4

试试这个：

sudo apt-get install nodejs

Answer 5

我遇到了与您类似的问题，除了我，我只收到与 json gem 相关的错误（相同的版本号和所有内容）。我找到了this solution，它对我有用（不过我必须先删除 Gemfile.lock）。希望对你有所帮助！
