我正在尝试从源代码构建Firefox（60.esr）。我遵循了Build Firefox on Windows中提到的步骤。但是失败了。
方法1： 我按照Windows Build Instruction中提到的所有步骤进行操作。 生成过程因错误而失败。
0:24.36 ERROR: Could not find LLVM/Clang installation for compiling stylo build-time
0:24.36 bindgen. Please specify the 'LLVM_CONFIG' environment variable
0:24.36 (recommended), pass the '--with-libclang-path' and '--with-clang-path'
0:24.36 options to configure, or put 'llvm-config' in your PATH. Altering your
0:24.36 PATH may expose 'clang' as well, potentially altering your compiler,
0:24.36 which may not be what you intended.
所以，我尝试了方法2。
方法2： 因为期望LLVM / clang，所以我安装了LLVM / Clang 6.0，并在环境变量中添加了 LLVM_CONFIG 。
然后我执行了mach build。添加LLVM_CONFIG修复了方法1中引起的错误。
但是构建再次失败并出现错误。

我什至在Bugzilla提出了一个要求。但是我还没有找到任何解决方案。
