如何解决由于LLVM无法在python 3.7.5和Ubuntu 18.04上安装vaex？
尝试使用sudo pip3 install vaex安装vaex软件包
但是出现以下错误：
got version from file /tmp/pip-build-4ejf0kw2/llvmlite/llvmlite/_version.py {'version': '0.34.0','full': 'c5889c9e98c6b19d5d85ebdd982d64a03931f8e2'}

任何人都可以指导我解决问题吗？

解决方法
解决方案是从dist-packages（所有版本）中手动删除llvm软件包，安装pip（最新版本）而不是pip3。 在此之后，我已经安装了llvmlite 0.33.0和numba 0.49.1。
重新安装了vaex，重新安装了llvmlite 0.34.0和numba 0.51，并且vaex的安装成功完成！
