[英]cannot install llvm using homebrew on macOS mojave
when I use brew install llvm
, this error appears:当我使用
brew install llvm
时,出现此错误:
Error: cmake: undefined method `on_linux' for #<Class:0x00007f7f744bf6b8>
I happened to have a Mojave machine and re-did the installation process myself, and it works fine.我碰巧有一台 Mojave 机器,我自己重新做了安装过程,它工作正常。
Here is what I did:这是我所做的:
brew install llvm
(I actually used brew reinstall llvm
, since it is reinstall
for me) brew install llvm
(我实际上使用了brew reinstall llvm
,因为它是为我reinstall
的)echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile
, brew version would be on your PATH
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.bash_profile
,brew 版本将在您的PATH
上source ~/.bash_profile
, apply the PATH
change source ~/.bash_profile
,应用PATH

==> Caveats
To use the bundled libc++ please add the following LDFLAGS:
LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
llvm is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have llvm first in your PATH run:
echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> /Users/rchen/.bash_profile
For compilers to find llvm you may need to set:
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"
