pipenv update出错解决方案

首先上报错信息:

Running $ pipenv lock then $ pipenv sync.
Locking [dev-packages] dependencies...
Locking [packages] dependencies...
env/utils.py", line 402, in resolve_deps
    req_dir=req_dir
  File "/usr/local/lib/python3.6/dist-packages/pipenv/utils.py", line 250, in actually_resolve_deps
    req = Requirement.from_line(dep)
  File "/usr/local/lib/python3.6/dist-packages/pipenv/vendor/requirementslib/models/requirements.py", line 704, in from_line
    line, extras = _strip_extras(line)
TypeError: 'module' object is not callable

一直报TypeError: 'module' object is not callable错误

解决方法 ： 是因为pip的版本问题

pipenv version 2018.7.1 支持完美的pip版本是pip 18.0

所以 执行以下命令 重装pip为18.0(该命令只对当前项目的虚拟环境生效 不影响全局pip)

pipenv run pip install pip==18.0
