你可能把默认系统python安装的包和graalpython安装的包混在一起了。默认情况下，graalpython安装在与CPython (~/.local/lib/python3.8/site-packages/)相同的站点范围目录中。

解决这个问题的最简单方法是使用GraalPython支持的venv。例如：

$GRAALVM_HOME/bin/graalpython -m venv /path/to/my/new/venv
. /path/to/my/new/venv/bin/activate
python -c 'import platform; print(platform.python_implementation())'
# output: GraalVM
python -m ginstall install pandas
# to end the venv session:
deactivate
python -c 'import platform; print(platform.python_implementation())'
# output: CPython

我发现~/.bash_profile中有很多环境变量。我注释了所有它们，并成功地编译了numpy/pandas。顺便问一下，我如何验证gcc/clang的设置是否正确？不管怎样，谢谢你的帮助。
