Question

安装我的要求失败：

» pipenv --python 3.6.4 install

为什么Python 2.7？让我们检查一下virtualenv中使用的python版本：

» pipenv shell
Spawning environment shell (/bin/bash). Use 'exit' to leave.
. /home/myuser/.local/share/virtualenvs/svc-J_VF07t3/bin/activate
» . /home/myuser/.local/share/virtualenvs/svc-J_VF07t3/bin/activate
» python --version
Python 3.6.4

正确！那么pipenv本身呢？

» which pipenv
/home/myuser/.local/bin/pipenv

所以似乎问题在于，虽然我的virtualenv正在使用Python 3，但pipenv本身正在使用Python 2（系统Python）。 pipenv已使用系统范围的python解释器安装为recommended：

pip install --user pipenv

确实安装了，发现：

» which pipenv
/home/myuser/.local/bin/pipenv

» pipenv --version
pipenv, version 11.1.3

根据我的项目将要使用的python解释器强制重新安装pipenv没有任何意义。

为什么pipenv在virtualenv中安装包时使用系统python，而不是使用那个virtualenv的python？如何解耦pipenv使用的python解释器和我的项目使用的python解释器？

Answer 1

我有一个非常相似的问题。当摆弄pipenv和新的次要版本的python 3时，它开始发生。听起来似乎无济于事，解决方案是打开一个新的shell（不采购该shell），并调用pipenv shell就像我的python manage.py命令。

以前我的错误是在整个字符串插值'%d' % foo中抱怨python 2.7，但这在python 3中有效。
