pipenv错误解决:TypeError: "module" object is not callable
Python note pipenv solution软件版本
今天在折腾一台新的云主机，所以我在安装环境的时候pip和pipenv都选择安装了最新版本
（注：正是这两个版本配合才会出现下面的报错，旧版本或以后的新版本的 Pipenv 不会出现）。
具体如下：
// pipenv 的版本 2018.7.1
$ pipenv --version
pipenv, version 2018.7.1
// pip 的版本 18.1
$ pip --version
pip 18.1 from /usr/bin/python3.6/lib/python3.6/site-packages/pip (python 3.6)
报错日志
$ pipenv install

解决方案 1 - 降 pip 版本
这个错误是由于pipenv和最新版本的pip（18.1）一起配合使用导致的 pipenv 中的一个错误，所以解决方法就是将 pip 的版本降到18.0即可。（问题讨论见issue 2924）
执行下面的命令：
sudo pip install pip==18.0
解决方案 2 - 升 pipenv 版本
上面的做法是自行解决的方案，还有一种方案就是更新到最新版的pipenv 2018.10.9 （新版本中该问题被得到解决 #2935）
具体的解决方案，参考官方的comment：
Also you can upgrade pipenv to the latest version.
If you have further problems please open a new issue.
I’m going to lock this thread for now to prevent
continued discussion as this is resolved.
To summarize for people on earlier releases than `2018.10.9`:
you can pin pip inside the virtualenv using
`pipenv run python -m pip install pip==18.0`
or you can set the environment variable
`PIP_SHIMS_BASE_MODULE=pipenv.patched.notpip`
不过可能是我使用的 pip 源是清华的镜像站，截止到发文，该镜像站还未同步到官方指出的2018.10.9版本，懒得折腾了，所以采用了降 pip 版本的方案。
