我尝试uvloop在 CentOS 7 上安装到 Python 3.9 venv。这些都是我采取的所有措施：
cd ~
mkdir python_envs
cd python_envs
python -m venv test
source test/bin/activate
pip install --upgrade pip
pip install uvloop
然后我得到这个：
Collecting uvloop

我认为关键的错误信息是error: [Errno 13] Permission denied: './configure'，但我不知道这发生在哪个目录。我已经阅读了此答案和一些相关信息，但似乎无法解决我的问题：
pip install failed with: OSError: [Errno 13] Permission denied on directory
install in env：如您所见，我在全新的环境中执行此操作，但无法正常工作。pip install --user: 不行，我明白了：
ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
pip install --user+ 修改环境include-system-site-packages = false中true的pyvenv.cfg：可以开始安装，但是回到原来的权限被拒绝的问题。sudo: 不安全，会引起其他问题。我将把它作为最后的解决方案。chmod -R 777 test：这不是一个解决方案，只是一个测试，以确保问题不在 env 目录的权限上。同样的权限问题仍然存在。我知道有一些不同的安装方法可以避免这个权限问题，但我想知道原因，有没有办法在pip install -r requirement.txt不处理这种特殊情况的情况下正常工作？
更新：
即使我这样做
sudo -s # become root
source test/bin/activate
pip install uvloop
仍然发生同样的问题error: [Errno 13] Permission denied: './configure'。我不知道这怎么会发生。
