我遇到了一个奇怪的问题。我尝试安装 x264。当运行 sudo ./configure --enable-shared 时，它给出了：
Found no assembler Minimum version is yasm-0.7.0 If you really want to compile without asm, configure with --disable-asm.

Maybe you should rebuild the yasm for the correct path /usr/bin/yasm.
也许您应该为正确的路径 /usr/bin/yasm 重建 yasm。

sudoignores your PATHenvironment variable and uses its own.
sudo忽略您的PATH环境变量并使用它自己的。
compare:
相比：
$ which yasm
/usr/local/bin/yasm
with:
和：
$ sudo which yasm
/usr/bin/yasm
To solve, do:
要解决，请执行以下操作：
$ sudo PATH=$PATH:/usr/local/bin which yasm
/usr/local/bin/yasm
or rather
更确切地说
$ sudo PATH=$PATH:/usr/local/bin ./configure --enable-shared

The error message means that you have an old version of yasm on your system, so you should update it! see here: https://trac.ffmpeg.org/wiki/CompilationGuide/Quick/libx264
该错误消息意味着您的系统上有旧版本的 yasm，因此您应该更新它！见这里：https: //trac.ffmpeg.org/wiki/CompilationGuide/Quick/libx264

Just in case of someone got here from Google, looking for a recent solution.
以防万一有人从谷歌来到这里，寻找最近的解决方案。
Recent versions of x264 moved from yasm to nasm, hence breaking some FFMPEG install scripts or tutorials. To check if it is the case, look at the output. If it reads
x264 的最新版本从 yasm 移动到 nasm，因此破坏了一些 FFMPEG 安装脚本或教程。要检查是否是这种情况，请查看输出。如果它读
Minimum version is nasm-2.13
then you are to install nasm. In Ubuntu 16.04 repos there's nasm 2.11; so you'll have to build from sources, following official instruction http://www.linuxfromscratch.org/blfs/view/svn/general/nasm.html.
然后你要安装nasm。在 Ubuntu 16.04 存储库中有 nasm 2.11；所以你必须按照官方说明http://www.linuxfromscratch.org/blfs/view/svn/general/nasm.html从源代码构建。
