为什么 python setup.py bdist_wheel 编译 wheel 会影响其他的包?

Question

首先我用 sa 用户登录到一台 arm linux 上

然后

mkdir ~/pypi
cd ~/pypi
wget https://files.pythonhosted.org/packages/cf/01/e8a380dc6e92a76113f034c58c9ffdbd115753e9b944ddf5d2dbe862f248/pydantic-1.10.11.tar.gz
tar -xvzf ./pydantic-1.10.11.tar.gz 
cd pydantic-1.10.11/
sudo yum install -y gcc make cmake python3-devel

准备好了一切工作，最后

python3 setup.py bdist_wheel

结果报错了

[sa@adv-node pydantic-1.10.11]$ python3 setup.py bdist_wheel

我不理解，我在 /home/sa/pypi/pydantic-1.10.11 下面执行 python3 setup.py bdist_wheel 关系统路径什么事情？关这个 torchvision 什么事情？

Answer 1

看报错时访问了没权限的目录报的错，改一下权限：

sudo chmod -R o+r /usr/local/lib64/python3.7/site-packages/torchvision-0.14.1.dist-info

或者用虚拟环境：

python3 -m venv myenv
source myenv/bin/activate
cd ~/pypi/pydantic-1.10.11/
python setup.py bdist_wheel
