斗罗安装dldl-gm后台bundler环境和依赖报错解决方案

安装 bundler 报错：

ERROR: Could not find a valid gem ‘bundler’ (= 1.17.3), here is why: Unable to download data from https://rubygems.org/ – Errno::ENETUNREACH: Network is unreachable – connect(2) for “api.rubygems.org” port 443 (https://api.rubygems.org/specs.4.8.gz)

1.添加国内源：

gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/

注意：如果之前自己瞎捣鼓已配置过源，建议先清理：

gem sources --remove https://rubygems.org/ gem sources --add https://gems.ruby-china.com/

2.验证当前源：

gem sources -l

应该显示：

*** CURRENT SOURCES ***
https://gems.ruby-china.com/

3.安装 bundler：

gem install bundler -v 1.17.3

或离线安装（下载 .gem 文件）：

gem fetch bundler -v 1.17.3

本地安装：

gem install ./bundler-1.17.3.gem

安装完成后运行：

bundle -v

应输出：

Bundler version 1.17.3

到这里环境已经安装成功！

安装依赖并启动：

cd /home/root/dldl-gm && sh restart-alpha.sh

会报错如下：

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.
Fetching source index from http://rubygems.org/

Retrying fetcher due to error (2/4): Bundler::HTTPError Could not fetch specs from http://rubygems.org/
Retrying fetcher due to error (3/4): Bundler::HTTPError Could not fetch specs from http://rubygems.org/

解决方案一：

全局配置 Bundler 使用 Ruby China 镜像（HTTPS）

bundle config set --global mirror.http://rubygems.org https://gems.ruby-china.com
bundle config set --global mirror.https://rubygems.org https://gems.ruby-china.com

验证配置：

bundle config list

应看到类似：

Settings are listed in order of priority. The top value will be used.
mirror.http://rubygems.org
Set via BUNDLE_MIRROR__HTTP://RUBYGEMS__ORG: “https://gems.ruby-china.com”
mirror.https://rubygems.org
Set via BUNDLE_MIRROR__HTTPS://RUBYGEMS__ORG: “https://gems.ruby-china.com”

这会把所有对 rubygems.org 的请求（无论 HTTP/HTTPS）都重定向到 https://gems.ruby-china.com

解决方案二：

打开：/home/root/dldl-gm/Gemfile和Gemfile.lock

把文件里面的：http://rubygems.org/ 改为 https://gems.ruby-china.com/

重新安装依赖并启动：

cd /home/root/dldl-gm && sh restart-alpha.sh

应看到类似：

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.

恭喜您，这就是已经在正常安装依赖了！
