Question

新的，新的CentOS 7.0 VM Rbenv安装不会为我安装红宝石

[vagrant@ad-proxy ~]$ rbenv install 2.2.4
Downloading ruby-2.2.4.tar.bz2...
-> https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.4.tar.bz2
error: failed to download ruby-2.2.4.tar.bz2

BUILD FAILED (CentOS Linux 7 using ruby-build 20170405-4-g365dd1f)

通过更详细的记录显示

[vagrant@ad-proxy ~]$ rbenv install 2.2.4 -v
/tmp/ruby-build.20170515092651.20803 ~
Downloading ruby-2.2.4.tar.bz2...

error: failed to download ruby-2.2.4.tar.bz2

BUILD FAILED (CentOS Linux 7 using ruby-build 20170405-4-g365dd1f)

问题似乎源于curl，例如

[vagrant@ad-proxy ~]$ curl https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.4.tar.bz2
curl: (35) Peer reports incompatible or unsupported protocol version.
[vagrant@ad-proxy ~]$ curl https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.4.tar.bz2 -v

Answer 1

您失败的原因：

当您访问某个网址时，某些旧的/易受攻击的NSS会在cURL库中用于SSL，因此会被拒绝。因此，在这台机器中，您可能无法运行与cURL相关的命令，例如pycurl。

解决方案：

IMO NSS与CentOS 7.0 VM捆绑在一起，因此您可以按照以下步骤更新NSS库。

yum update nss nss-util nspr

希望这有帮助！

Answer 2

在我的情况下，更新docker run -v /home/<host user>/.ssh:/home/<docker user>/.ssh <image>并结合nss更新帮助。

如何修复错误：无法在rbenv安装上下载
