我为我的project1安装了1.2.0版本的kafka包，当我为project2安装1.3.0版本时，以前的版本被覆盖了，然后project1无法运行。我能做些什么来保持两个项目正常运行?

Uninstalling kafka-1.2.0:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
totems-pycommon 1.0.0 requires kafka==1.2.0, but you have kafka 1.3.0 which is incompatible.

您可以使用python的venv创建带有独立包的独立环境
要创建一个环境，可以使用以下命令:
python3 -m venv /some/path/env-name
/some/path/env-name/Scripts.bat # on Windows
source /some/path/env-name/bin/activate # on Linux
当环境处于活动状态时安装的包仅在该环境中可用。通过为每个项目设置一个环境，您可以避免您正在谈论的那种冲突。
