Question

我尝试在macOS中更新gem，但发生以下错误：

$ RUBYOPT= gem update --system
ERROR:  While executing gem ... (NoMethodError)
    undefined method `ssl_version=' for #<OpenSSL::SSL::SSLContext:0x007f8561047638>
Did you mean?  ssl_timeout=

gem update和gem install {package_name}的输出是相同的。

gem env version或gem --version的输出为：

3.0.3

openssl version的输出是：

LibreSSL 2.6.5

如何解决该问题？

macOS版本：10.14.4

gem env的输出：

ruby -ropenssl -e "puts OpenSSL::OPENSSL_LIBRARY_VERSION"的输出：

rvm list的输出：

=* ruby-2.4.0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

UPDATE ：完全删除rvm和rbenv（并重新启动Terminal会话）后，我尝试再次执行gem update，这是结果：

$ gem update
Updating installed gems
Updating CFPropertyList
Fetching: CFPropertyList-3.0.0.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

我认为它现在再次使用了macOS的系统ruby。

以下是一些输出：

gem -v的输出：

2.5.2.3

ruby -v的输出：

红宝石2.3.7p456（2018-03-28修订版63024）[universal.x86_64-darwin18]

which gem的输出：

/ usr / bin / gem

which ruby的输出：

/ usr / bin / ruby

我的目标是毫无问题地使用gem（安装和更新等）。接下来我该怎么办？

Answer 1

def get_context_data(self, *args, **kwargs): context = super(PostFeed, self).get_context_data(**kwargs) context["posts"] = Post.objects.all() return context出现在ruby 1.8.7中，mac os内置了2.3.7。

只需在10.14.2上进行检查-

OpenSSL::SSL::SSLContext#ssl_version=

即使在系统ruby上也可以正常工作，OpenSSL版本与您的相同。

唯一值得怀疑的是rbenv与rvm冲突，因为您已经安装了它们，这可能会使加载的库和ruby编译混乱。我建议完全删除其中之一（也不要忘记在此之后开始新的Shell会话）并重新安装损坏的红宝石。

gem更新引起的错误：未定义的方法ssl_version
