最近查API有点频繁,导致Dash每次的查询时需要等待10秒的频率指数式增长,最后变成每查一次都要等10秒,真是急死人,免费版用户果然没人权。一怒之下换用开源的DevDocs。
为了方便,我使用了作者提供的Dockerfile构件镜像,结果构建到这一步挂了
Step 8 : RUN bundle install --system

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

Gem::RemoteFetcher::FetchError: Errno::ECONNREFUSED: Connection refused - connect(2) for "rubygems.global.ssl.fastly.net" port 443 (https://rubygems.org/gems/i18n-0.7.0.gem)
An error occurred while installing i18n (0.7.0), and Bundler cannot continue.
Make sure that `gem install i18n -v '0.7.0'` succeeds before bundling.
The command '/bin/sh -c bundle install --system' returned a non-zero code: 5
由于之前很少折腾Ruby,感觉不明觉历,于是手动构建了一个容器逐步执行Dockerfile内容,最后还是挂在这一句:
Gem::RemoteFetcher::FetchError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A (https://rubygems.global.ssl.fastly.net/gems/i18n-0.7.0.gem)
An error occurred while installing i18n (0.7.0), and Bundler cannot continue.
Make sure that `gem install i18n -v '0.7.0'` succeeds before bundling.
按照提示,尝试gem install i18n -v '0.7.0':
root@4c1e62ed5408:/devdocs# gem install i18n -v '0.7.0' --source http://rubygems.org
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A (https://rubygems.global.ssl.fastly.net/quick/Marshal.4.8/i18n-0.7.0.gemspec.rz)
看上去像SSL出错的,于是开始了漫长的Google and Try,使用了各种姿势却依然无法解决,折腾了一个多小时。
最后灵光一闪,妈蛋该不会是被墙了吧(容器没装梯子)?
改个源:
bundle config mirror.https://rubygems.org https://ruby.taobao.org
然后一大串字符滚过:
root@4c1e62ed5408:/devdocs# bundle install --system
