运行LNT runtest时遇到错误

Question

我打算使用 lnt 来运行测试。我在我的 Intel MacBook 上遵循了Quick Start。但是，当我进入

的步骤时

lnt runtest test-suite \
  --sandbox /tmp/BAR \
  --cc ~/llvm.obj.64/Release+Asserts/bin/clang \
  --cxx ~/llvm.obj.64/Release+Asserts/bin/clang++ \
  --test-suite ~/llvm-test-suite \
  --cmake-cache Release

zsh 说：

zsh: command not found: lnt

很好。所以我进入 ~/mysandbox/bin 并运行

./lnt runtest test-suite \
  --sandbox /tmp/BAR \
  --cc ~/llvm.obj.64/Release+Asserts/bin/clang \
  --cxx ~/llvm.obj.64/Release+Asserts/bin/clang++ \
  --test-suite ~/llvm-test-suite \
  --cmake-cache Release

这一次，更厉害的事情发生了：

Traceback (most recent call last):
  File "/Users/sunyi/mysandbox/lib/python3.11/site-packages/Jinja2-2.7.2-py3.11.egg/jinja2/_compat.py", line 113, in <module>

During handling of the above exception, another exception occurred:

Python环境好像有问题。你能提供一些解决这个问题的建议吗？

我所有的努力都在上面呈现。希望能顺利运行
