标签: python-2.7 pipenv pep8 pipfile

我试图锁定Pipfile并遇到以下错误:

$pipenv install
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
Building requirements...
Resolving dependencies...
✘ Locking Failed! 
[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could not be resolved. You 
likely have a mismatch in your sub-dependencies.
First try clearing your dependency cache with $ pipenv lock --clear, then try the original 
command again.
Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $ 
pipenv graph to inspect the situation.
Hint: try $ pipenv lock --pre if it is a pre-release dependency.

尝试运行建议的命令,但仍然相同。

pipenv lock --clear

没关系,可以使用pipenv --support来解决。 原来pipenv使用的是python3。因此必须使用以下命令将其明确指向python2,这确实创建了Pipfile.lock

pipenv --two install
