我正在使用 Ruby on Rails 应用程序尝试 GitHub Actions for CI。

我的设置是使用 VM，而不是在容器中运行 Ruby 构建。

这是我的工作流程 yml。它一直运行而没有错误，直到步骤“设置数据库”。

我正在尝试在 Manjaro 中使用 docker（我的内核版本是 4.19）但它不起作用。

运行后，sudo pamac install docker我运行sudo systemctl start docker.service并收到此消息：

Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.

所以sudo systemctl status docker.service返回：

我目前正在尝试为一个项目设置Elasticsearch。我已经安装Elasticsearch 7.4.1并且还安装了Java，即openjdk 11.0.4.

但是当我尝试使用命令启动Elasticsearch 时

sudo systemctl start elasticsearch

我收到以下错误

elasticsearch.service 的作业失败，因为控制进程退出并显示错误代码。

有关详细信息，请参阅“systemctl status elasticsearch.service”和“journalctl -xe”。

当我尝试运行命令时

systemctl status elasticsearch.service

我收到错误消息

? elasticsearch.service - 弹性搜索

已加载：已加载（/usr/lib/systemd/system/elasticsearch.service; 已禁用; 出售

活动：自 UTC 时间周五 2019-11-01 06:09:54 起失败（结果：退出代码）；12 秒前

Run Code Online (Sandbox Code Playgroud)

进程：5960 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -p ${PID_DI

主PID：5960（代码=退出，状态=1/FAILURE）

我已经从我的机器上删除/清除了Elasticsearch并重新安装了几次，但它似乎没有解决问题。

我试图修改默认network.host，并host.port设置在/etc/default/elasticsearch以network.host: 0.0.0.0和http.port: 9200解决这个问题，但还没有运气。

我需要一些帮助。提前致谢。

我刚刚安装了 PostgreSQL，我正在尝试安装 pgdmin4，但是每当我运行下面的命令来安装 pgadmin4 和 pgadmin4-apache2

sudo apt install pgadmin4 pgadmin4-apache2

我经常收到错误

E: 包 'pgadmin4' 没有安装候选

E: 无法定位包 pgadmin4-apache2

我尝试了很多解决方案，但似乎没有一个能解决问题。我需要帮助。

我尝试更改默认捆绑版本，但它已更新为 2 个默认版本。如何修改为单一默认值？

$ gem list bundler

*** LOCAL GEMS ***

bundler (2.0.1, default: 1.16.6, default: 1.16.2)

如果我执行 gem uninstall 不删除默认值，

$ gem uninstall bundler
Successfully uninstalled bundler-2.0.1


$ gem list bundle

*** LOCAL GEMS ***

bundler (default: 1.16.6, default: 1.16.2)

如何将（如下所示）默认设置为单一版本？

bundler (2.0.1, default: 1.16.6)
