Could not install all the requirements

希望成功安装venv，但遇到上述错误。

您/用户/jillasai.krishna/pi-tcms-1/pi-tcms/requirements.txt包含cheetah==2.4.4。此版本的Cheetah仅适用于Python2，您正在尝试与Python3一起使用

可以将项目与Python 2.7一起使用，也可以将项目升级到Python 3。支持Python 2.7和3.4+

---

首先要尝试的是用Cheetah3==3.2.4替换cheetah==2.4.4。

看起来您的python版本与venv.c02s86lufvvh7 blr:pi tcms jillasai.krishna$python python python 2.7.10 default，2017年10月6日，22:29:07[GCC 4.2.1兼容Apple LLVM 9.0.0.0 clang-900.0.31]不同，关于达尔文类型帮助，版权，有关详细信息，请参阅学分或许可证。这是我的蟒蛇version@loki请帮助我如何了解venv版本？您是否分别从克隆的repo创建了venv？我已从GitHub克隆了一个repo，并在该repo中运行source-venv.source命令。在虚拟环境中安装需求=====================================执行：pip install-r/Users/jillasai.krishna/pi-tcms-1/pi-tcms/requirements.txt错误：无法从-r/Users/jillasai.krishna/pi-tcms-1/pi-tcms/requirements.txt中找到满足cheetah==3.2.4要求的版本：1.0、2.0rc7、2.2.1、2.2.2.3.0、2.4.0、2.4.1、2.4.3、2.1、2.4.3，2.4.4错误：在-r/Users/jillasai.krishna/pi-tcms-1/pi-tcms/requirements.txt第1行中未找到cheetah==3.2.4的匹配发行版。无法安装所有需求。我不确定如何将项目升级到Python 3，我将cheetah==2.4.4替换为Cheetah3==3.2.4，现在面临上述错误。Cheetah3==3.2.4，而不是cheetah==3.2.4。
