我正在尝试创建一个将创建 AppIndicator 的 Vala 应用程序。

问题是，当我编译我的应用程序时，我收到以下错误：

Package `appindicator3-0.1' not found in specified Vala API directories or GObject-Introspection GIR directories

我像这样编译应用程序：

 valac --pkg appindicator3-0.1 --pkg gtk+-3.0 indicator.vala

我安装了 libappindicator-dev 并安装了 gir1.2-appindicator3-0.1。

我错过了什么？

谢谢你。

我刚刚格式化了我的笔记本电脑并全新安装了 Ubuntu 18.04。在安装我的一些开发包时，我发现使用 ruby​​gems 和 python pip 都有问题。它给出了与 SSL 相关的错误。我也无法访问他们的网站。（连接重置错误消息）

这是安装最新版本 PIP 的错误

编辑：

我什至无法使用 curl 连接到 curl 网站：

我试图更新 openssl 和 ca-certificates 包，但同样的问题。 Openssl 版本： OpenSSL 1.1.0g 2017 年 11 月 2 日

有人知道发生了什么吗？这在几天前的虚拟机中并没有发生。

编辑在连接到同一网络并以相同方式配置的 VM 中再次测试，它可以正常工作！！真的很奇怪。

谢谢你。
