sys.ext（cli（））文件“/usr/local/var/pyenv/versions/3.8.2/lib/python3.8/site packages/pipenv/vvendor/click/core.py”，
普通的pipenv install
pipenv install tensorflow Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

虽然官网上说目前还不支持3.8版本，但是到pypi上看有3.8的whl包，再好像是sof有关问题的回答，改用whl安装通过
pipenv install https://pypi.doubanio.com/packages/d5/13/594694d5eced4375ee6ba0937fc0157179a0dd32d7222699091160a5631c/tensorflow-2.2.0-cp38-cp38-macosx_10_11_x86_64.whl#sha256=bbcfb04738099bd46822db91584db74703fdddacf4cd0a76acfc5e086956b5ba
pytorch安装时出错log和上面的error log一样，相同方法解决
但上面的方法有缺陷，pipfile的那个位置编程下面这样：
tensorflow = {file = "https://pypi.doubanio.com/packages/d5/13/594694d5eced4375ee6ba0937fc0157179a0dd32d7222699091160a5631c/tensorflow-2.2.0-cp38-cp38-macosx_10_11_x86_64.whl"}到另外一个操作系统环境下，这个pipfile不可用，得手动改一下，这样影响CICD。
最后用pyenv装了个python3.7，解决了纯指令安装问题。
后来又碰到这个问题，bing查了一下，sof有这么一个解释：https://stackoverflow.com/questions/51255947/pipenv-install-failing-due-to-timeout ,里面的方法经试用有效：
export PIPENV_TIMEOUT=9999 export PIPENV_INSTALL_TIMEOUT=9000
