Question

我最近使用自制软件在Macbook air上安装了emscripten。但是，当我尝试运行它时，即使我执行简单的emcc --version也会收到错误llc executable not found at /usr/bin/llc。我该如何解决？

Answer 1

解决方案：尚未安装llvm，所以在brew install llvm之后加上echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.zshrc为我解决了这个问题。

Answer 2

嗯。好像添加brew install llvm一样，我仍然无法拨打llvm。

所以我刚刚安装了brew install emscripten 然后我做了emcc给我

Welcome to Emscripten!

This is the first time any of the Emscripten tools has been run.

A settings file has been copied to /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten, at absolute path: /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten

It contains our best guesses for the important paths, which are:

  LLVM_ROOT       = /usr/bin
  NODE_JS         = /usr/local/bin/node
  EMSCRIPTEN_ROOT = /usr/local/Cellar/emscripten/1.39.18/libexec

Please edit the file if any of those are incorrect.

This command will now exit. When you are done editing those paths, re-run it.

然后我再次做emcc，给了我BINARYEN_ROOT is set to empty value in /usr/local/Cellar/emscripten/1.39.18/libexec/.emscripten。

您如何设置BINARYEN_ROOT？我在最新的macos 10.15.5上。

在OSX 10.15上安装并运行emscripten
