Virtualenv: Virtualenv无法复制内置库

问题

我创建了一个虚拟环境，/ lib / Python目录没有内置库（只有site-Package）。
因为我要用它。

环境
的Python：3.8.1
至少提供：

  • 作业系统：Centos7.8
  • 安装了virtualenv的主机python的pip list ：

虚拟环境创建的输出

确保使用-vvv --with-traceback运行创建：

stackoverflow.com/questions/23258029/virtualenv-doesnt-copy-all-py-files-from-lib-python-directory

它仅复制了部分内置软件包，并且仅用于python 2。

我创建了一个虚拟环境，/ lib / Python目录没有内置库（只有site-Package）。
因为我要用它。

那是设计使然。 您可能需要进一步扩展您的使用方式以及使用原因。

我知道我可能不应该在这里问问题，但是我真的不知道该去哪里，所以对不起。

请提供有关到达目的地的详细分步指南。 理想情况下是docker映像。

  1. 编译python381
  2. 安装pip virtualenv
  3. 创建虚拟环境./virtualenv -vvv --always-copy --clear / opt / env_test
  4. 将libpython3.8.so.1.0文件复制到/ opt / env_test / lib
  5. 压缩/选择/ env_test
  6. scp到另一台机器并解压缩
  7. 将LD_LIBRARY_PATH设置为libpython3.8.so.1.0
  8. / env_test / bin / python3

虚拟环境是对全局python的引用，并不是要独立存在。 它们无意复制到另一台计算机上。 除非您还复制全局python并以复制模式创建虚拟环境，否则它们将不起作用。 参见https://www.youtube.com/watch?v=o1Vue9CWRxU
