Pipenv没有认识到Pyenv版本？

Question

我安装了Python 3.7.0,但对于特定的Django项目,我想使用Python 3.6.5.使用pyenv此目的,在我的MacBook Pro我跑brew install pyenv,其次pyenv install 3.6.5,在项目的根目录下,pyenv local 3.6.5.我已经验证Python版本3.6.5是活动的:

Kurts-MacBook-Pro-2:lucy-web kurtpeek$ cat .python-version
3.6.5
Kurts-MacBook-Pro-2:lucy-web kurtpeek$ pyenv versions
  system
* 3.6.5 (set by /Users/kurtpeek/Documents/dev/lucy2/lucy-web/.python-version)

在Pipfile我使用的是类似以下内容:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]

[dev-packages]

[requires]
python_version = "3.6.5"

但是,当我运行时pipenv shell,我得到它'默认'到我的系统版本,python 3.7.0:

Kurts-MacBook-Pro-2:lucy-web kurtpeek$ pipenv shell
Loading .env environment variables...
Warning: Your Pipfile requires python_version 3.6.5, but you are using 3.7.0 (/Users/k/.local/share/v/l/bin/python).
  $ pipenv check will surely fail.
Launching subshell in virtual environment…
bash-3.2$  . /Users/kurtpeek/.local/share/virtualenvs/lucy-web-CVxkrCFK/bin/activate
(lucy-web-CVxkrCFK) bash-3.2$

现在,如果我尝试运行python manage.py shellDjango项目的shell,我得到一个SyntaxError我怀疑与Python 3.7密切相关的东西,因为我确信它之前有效:

(lucy-web-CVxkrCFK) bash-3.2$ python manage.py shell

SyntaxError: Generator expression must be parenthesized

然而,我认为其根本原因在于它是在Python 3.7.0中运行而不是在Python 3.6.5中运行.

是pipenv与pyenv不是"兼容"彼此？

Answer 1

Pipenv知道Pyenv,但它不会自动使用相同的Python版本,除非你告诉它这样做.在Pipenv文档中有一个关于此的说明.

您可以告诉Pipenv使用特定的Python版本,例如

pipenv install --python 3.6.5

或者您可以将环境变量设置为默认为Pyenv版本,例如

export PIPENV_PYTHON="$PYENV_ROOT/shims/python"
