为什么 Carla/终端找不到我的 Clang8 安装？

编程问答 2022-05-26

问题描述

我正在尝试遵循本教程：https://carla.readthedocs.io/en/latest/build_linux/ 和此 GitHub 文件：https://github.com/carla-simulator/carla/pull/2433/files/a112caacfd96619af9ba4439497cff0b208378cf

我正在执行“make launch”/“make PythonAPI”步骤并不断收到此错误：

(CARLA) Daniels-iMac:carla danieljones$ make launch
clang 8 is required,but it's not installed.
make: *** [setup] Error 1
(CARLA) Daniels-iMac:carla danieljones$

carla repo 被克隆到：/Users/danieljones/carla 我通过终端安装了 llvm@8，它似乎已保存到：/usr/local/Cellar/llvm@8/8.0.1_3。终端给了我做一个“导出”命令和我做的“回声”的建议。我对终端缺乏了解，但我明白这些应该通知系统保存包的位置？

当我在终端中尝试 clang --version 时，我确实得到：

clang version 8.0.1 (tags/RELEASE_801/final)
Target: x86_64-apple-darwin20.3.0
Thread model: posix
InstalledDir: /usr/local/opt/llvm@8/bin

这让我觉得终端能够找到 clang8 但 carla 中的某些东西正在挣扎。

我发现以前的堆栈建议更改 Setup.py、Setup.sh 和 BuildPythonAPI.sh 以将它正在寻找的 clang 值更改为 Apple 安装的值，但没有解决我的问题。

更新： 我设法将 clang8 安装到我的 CARLA 环境中，make launch 现在正在取得进展，但给了我错误：

  is not able to compile a simple test program.

  It fails with the following output:

更新 2： 将 setup.sh 文件中的 clang-8 路径更改为 anaconda3 venv 中的目录后，我设法 make launch 但现在出现此错误：

Setup.sh: Extracting boost for Python 3.
