Question

我按照此处的说明尝试安装UnrealEngine4：https://github.com/Microsoft/AirSim/blob/master/docs/build_linux.md。

当我在UnrealEngine4存储库中运行./Setup.sh时，出现以下错误：

The following packages have unmet dependencies:
 clang-3.8 : Depends: libclang1-3.8 (= 1:3.8-2ubuntu1) but it is not going to be installed
             Depends: libobjc-5-dev but it is not going to be installed
             Depends: libclang-common-3.8-dev (= 1:3.8-2ubuntu1) but it is not going to be installed
             Recommends: llvm-3.8-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

这导致我尝试安装llvm-3.8-dev

sudo apt-get install llvm-3.8-dev

最终导致了这个问题：

The following packages have unmet dependencies:
 llvm-3.8-dev : Depends: libllvm3.8 (= 1:3.8-2ubuntu1) but 1:3.8-2ubuntu4 is to be installed
E: Unable to correct problems, you have held broken packages.

如何卸载libllvm3.8 (1:3.8-2ubuntu4)？

其他信息：

$ dpkg -l | grep llvm

Answer 1

sudo apt install package = version

您应该安装包添加版本号

的包

sudo apt install llvm-3.8-dev = 1：3.8-2ubuntu1

如何卸载`libllvm3.8（1：3.8-2ubuntu4）`并安装`libllvm3.8（= 1：3.8-2ubuntu1）`？
