获取 ImportError：运行命令“pipenv shell”时无法导入名称“InstallCommand”

Question

当我执行以下步骤时，我得到了ImportError：

我安装了 pipenv

pip install pipenv

接下来，我为python创建虚拟环境并激活

python -m venv env
source ./env/Scripts/activate

最后，我运行命令

pipenv shell

我得到 ImportError

$ pipenv shell
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead. You can set PIPENV_VERBOSITY=-1 to suppress this warning.

我该如何解决？请帮我！谢谢！

Answer 1

这可能是由于机器的默认 python 版本。 您可以通过设置您将使用的默认 python 版本来解决此问题。

RUN update-alternatives --install /usr/bin/python python /usr/bin/python3.6 1
RUN update-alternatives --set python /usr/bin/python3.6
RUN curl -s https://bootstrap.pypa.io/get-pip.py -o get-pip.py && \
python get-pip.py --force-reinstall && \ rm get-pip.py
RUN pip3 install pipenv
RUN pipenv --python 3.6

注意：

1. python3.x 版本可以是您使用的任何版本。
2. 你必须在这些命令之前apt install python3.x。
