笔记

如果您想要requirements.txt锁定文件的输出，请运行 $ pipenv lock -r。然而，这将包括所有哈希值（这太棒了！）。要获得requirements.txt不带哈希值的 a，请使用 $ pipenv run pip freeze.

根据上面的pipelinev 通知，如果您想要requirements.txt锁定文件的输出，您应该运行$ pipenv lock -r. 但是，-r选项不存在：

$ pipenv lock -r
Usage: pipenv lock [OPTIONS]
Try 'pipenv lock -h' for help.
$ pipenv lock -h
Usage: pipenv lock [OPTIONS]

  Generates Pipfile.lock.

Options:
  --categories TEXT
  --dev-only             Emit development dependencies *only* (overrides
                         --dev)
  -d, --dev              Generate both develop and default requirements  [env
                         var: PIPENV_DEV]
  --extra-pip-args TEXT
  --pre                  Allow pre-releases.
  --python TEXT          Specify which version of Python virtualenv should
                         use.
  --clear                Clears caches (pipenv, pip).  [env var: PIPENV_CLEAR]
  -q, --quiet            Quiet mode.
  -v, --verbose          Verbose mode.
  --pypi-mirror TEXT     Specify a PyPI mirror.
  -h, --help             Show this message and exit.

requirements.txt我可以知道获取pipelinev 锁定文件输出的命令吗？

pipenv shell创建执行命令时出现以下错误：

为了在 heroku 上托管，我需要 pipenv shell。

我正在尝试以 root 身份运行 Pipenv python 实例。不以 root 身份运行时：

(myenv) $ python script.py

Pipenv python 使用正确。但是，当以 root 身份运行时sudo：

(myenv) $ sudo python script.py

/usr/bin/python而是使用系统默认的python at 。经过一番搜索，我找到了-Esudo 的选项。然而，随着

(myenv) $ sudo -E python script.py

它仍然使用/usr/bin/python，即使sudo -E echo $PATH给出相同的echo $PATH，所以该-E选项工作正常；但是，sudo -E which python继续给/usr/bin/python！这不是权限或访问问题，因为 Pipenv python 的完整路径可以正常工作。即使$PATH设置正确，为什么使用错误的二进制文件？

我正在尝试使用 pip 在我的 virtualenv 中安装各种要求，但我无法绕过错误Segementation fault (core dumped)。该错误似乎表明内存访问问题，但我不明白在 venv 中如何或为什么会发生这种情况。
