Ruby openssl 版本与系统的 openssl 不同

Question

我使用 rbenv 安装了 ruby​​ 2.3.0。安装 ruby​​ 后使用不同的 openssl，然后是我在我的操作系统中使用的。我该如何解决这个问题？

[cp@cloud pkgconfig]$ ruby -ropenssl -e 'puts OpenSSL::OPENSSL_VERSION'
  OpenSSL 1.0.1e 11 Feb 2013
[cp@cloud pkgconfig]$ openssl version
  OpenSSL 1.0.2k  26 Jan 2017

我尝试使用 openssl 选项重新安装 ruby​​，但出现以下错误

在 openssl dir 选项中提供可执行路径：

which openssl
/usr/bin/openssl

RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/bin/openssl” rbenv install 2.3.1

Answer 1

这都是关于 PATH 的。将搜索 PATH 环境变量中指定的目录以查找您发出的任何命令。所以 rbenv 必须在你的 PATH 前面添加一个目录，在其中找到一个名为 openssl 的命令，即 rbenv 的 openssl 版本。

怎么办？

1) 您可以尝试将包含系统 openssl 的目录移动到路径前面的 rbenv 目录前面，例如在 .bash_profile 或类似的底部：

export PATH="/path/to/openssl:$PATH"

2) rbenv 允许您在安装 ruby​​ 时指定包含 openssl 的目录：

$ RUBY_CONFIGURE_OPTS="--with-openssl-dir=/path/to/openssl” rbenv install 2.4.0

3) 您也许可以删除 rbenv 安装的 openssl 命令。您可以使用以下方式找出命令所在的第一个目录：

$ which openssl

但我不会删除该命令，而是将其mv 改成不同的名称，以防您以后需要它：

$ mv openssl rbenv_openssl

那么当在该目录中搜索 openssl 命令时将找不到，因此将按顺序搜索路径中的其他目录，直到找到系统的 openssl 命令。

如果更改 rbenv 的 openssl 的名称会破坏 rbenv，您可以将命令 mv 恢复为原来的名称。
