Question

我的应用无法构建甚至运行。它给我一个创建 CEF 浏览器失败的错误。直到今天，一切都运行良好。我按照此链接中的说明再次卸载并安装了 CEF：Big Changes and CEF 但它仍然给了我错误。这是控制台中的完整错误：

可能是什么问题？

这是一个 known issue Linux 现在。

<块引用>

UnsatisfiedLinkException (libjcef.so: libjawt.so) 在 Ubuntu 20 和其他一些 Linux 版本上，据报道，当运行安装了 CEF 的 Codename One 模拟器时，您会收到 UnsatisfiedLinkException，其中提到 libjcef.so 找不到 libjawt.so。这是因为JDK的lib目录不在LD_LIBRARY_PATH中。您可以通过添加它来解决此问题。例如

导出 LD_LIBRARY_PATH=$JAVA_HOME/lib/amd64
