Gem::Ext::BuildError: 错误：无法为 Puma Gem 构建 gem 原生扩展

Question

我已将我的 ruby​​ 项目从 Linux（使用 RVM）导入到 MacOSX（rbenv）。两者都使用相同版本的 rails & ruby​​。当我按照 GoRails 指南在两台机器上安装 RoR 时。

因此，当我将 sample_app 从 Linux 导入到 MacOSX 时，我运行了 bundle install。我安装了很多近 50-100 的宝石，但这个失败了。我不知道为什么它会失败。对我来说，它似乎无法编译某些 c 文件，但我不知道如何修复这些错误。谢谢

Answer 1

您需要自制软件和 openssl。运行brew install openssl 然后 bundle config build.puma --with-opt-dir=/usr/local/opt/openssl

然后运行bundle install 应该可以工作。

Answer 2

如果您使用 ubuntu 14.04 到任何升级版本，并且如果您在系统中安装了 OpenSSL，那么您只需要运行这些命令

首先只需获取 OpenSSL 正常安装的位置，如果您已安装在单独的位置，则它安装在此位置 /usr/bin/openssl 获取您的位置首先使用

 sudo find / -name openssl

然后

bundle config build.puma --with-opt-dir=/usr/bin/openssl

然后

bundle install 

除非你安装的OpenSSL路径正确，否则会成功

如果您在安装之前没有安装 OpenSSL，请使用

sudo apt-get install openssl

它将完美运行。 干杯

Answer 3

在 ubuntu 上安装 openssl ruby​​-openssl 和 libssl-dev 终于帮了我。

apt-get install openssl ruby​​-openssl libssl-dev

Answer 4

您是否尝试使用以下标志安装 gem？

-- --with-cflags="-Wno-error=implicit-function-declaration"
