安装pandas inn graalpython时遇到错误

问题描述

当我编译 graalpython -m ginstall install pandas 或 graalpython -m ginstall install bumpy 我收到以下错误，请评论如何修复错误。谢谢。

解决方法

您似乎混合了默认系统 python 安装的软件包和 graalpython 安装的软件包。默认情况下，graalpython 与 CPython (~/.local/lib/python3.8/site-packages/) 安装到同一个站点范围的目录中。

解决此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

发现~/.bash_profile里面有很多环境变量。我评论了所有这些并成功编译了 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。
