Pipenv: Pipenv 无法正确解析 --system python。

创建于 2017-10-31 · 46评论 · 资料来源: pypa/pipenv

描述你的环境

操作系统类型Docker Alpine Python -> https://github.com/docker-library/python/blob/1d59eb2dd813c64891bf554a8ea01754aba25816/3.6/alpine3.6/Dockerfile
Python 版本： Python 3.6.3
Pipenv 版本： pipenv, version 8.3.1

预期结果

如果我设置 PIP_PYTHON_PATH 它会被 pipenv 忽略和覆盖（我的问题是为什么，背后的原因是什么？）因为https://github.com/kennethreitz/pipenv/blob/master/pipenv/utils.py#L367它覆盖了这个 ENV当我使用标志--system时变量。我发现了这个问题，因为在构建我的 docker 镜像时，它在pipenv install --system上失败

为什么我知道这个？因为还有其他功能无法正常工作。
```(Pdb) python_path
'/斌/蟒蛇'
(Pdb) which('python')
'/斌/蟒蛇'
(Pdb) 打印 (sys.executable)
'/usr/local/bin/python'

/ # /bin/蟒蛇
sh: /bin/python: 未找到

I think issue is somewhere here: https://github.com/kennethreitz/pipenv/blob/1bf6f5101a3bf1dca78be814e742411cc5bdb2dd/pipenv/cli.py#L1440

        p = os.sep.join([location] + ['bin/{0}'.format(command)])

`` this should return /usr/local/bin/python but for some strange reason it's returning /bin/python`

实际结果

pipenv install --system安装应该不会因为找不到 /bin/python 而失败。

复制步骤

该 docker 映像上的pipenv install --system将失败

@kennethreitz问题没有解决，你能不能不要关闭尚未修复的东西。问题仍然可以重现。

@galuszkak这很有趣。所以sys.executable是根据 pdb 设置的，但是当我们实际调用which() ，我们没有传递您使用—system的事实，因此它尝试使用项目 virtualenv 位置这大概不存在。这是相关的调用，当我进入办公室时应该很容易修复： https :

至于我们为什么要这样做，主要是为了我们可以欺骗 pip-fools 包解析器来解析与活动解释器不同的 python 版本的 python 包

techalchemy 于 2017-10-31

使用这个 Dockerifle，它基于提交给这个 repo 的那个，我无法重现这个问题，不是说它不存在，看起来有些事情发生了，购买这个 dockerfile 似乎有效：

FROM python:alpine3.6

# -- Install Pipenv:
RUN set -ex && pip install pipenv --upgrade

# -- Install Application into container:
RUN set -ex && mkdir /app

WORKDIR /app

# -- Adding Pipfiles
ONBUILD COPY Pipfile Pipfile
ONBUILD COPY Pipfile.lock Pipfile.lock

# -- Install dependencies:
ONBUILD RUN set -ex && pipenv install --deploy --system

@erinxocon我没有使用 --deploy 标志 + 你没有使用 $PIP_PYTHON_PATH 这是这里的原始问题，它被 pipenv 覆盖。

galuszkak 于 2017-11-01

@galuszkak道歉；我明白这一点，我想我不确定为什么在这种情况下需要设置。我们绝对应该解决这个错误并修复它。我只是想知道 docker alpine 是否需要设置 PIP_PYTHON_PATH 。

erinxocon 于 2017-11-01

@erinxocon没什么好道歉的 :)，感谢您关注我的问题👍。我在 #1005 中提供的修复程序现在对我有用。

但是我尝试了您的图像，并且在同一组事物上运行得非常好。试图首先确定导致我的问题的原因，因为 sam Pipfile 和 Pipfile.lock 以及相同的 .env 文件在您的 Dockerfile 上听起来有效，我看不出有什么区别，因为我提供相同的图像...

galuszkak 于 2017-11-01

明白了@erinxocon ！以下是您如何重现该内容：

FROM python:3.6-alpine3.6

RUN set -ex && mkdir /app
ENV PIP_PYTHON_PATH=/usr/local/bin/python

galuszkak 于 2017-11-01

使用 ONBUILD RUN 与仅使用 RUN 似乎是一个问题。不是码头专家，我必须弄清楚它们之间有什么区别。

erinxocon 于 2017-11-02

@erinxocon我不认为这是问题所在。在上面的示例中，我向您展示了运行容器内的问题，而不是在任何步骤构建映像上。

galuszkak 于 2017-11-02

@erinxocon问题在于首先设置变量（实际上不需要设置，但这PIP_PYTHON_PATH当您需要传递--system时它会破坏解析器功能

def which(command, location=None, allow_global=False):
    if location is None:
        location = project.virtualenv_location

    if not allow_global:
        if os.name == 'nt':
            p = find_windows_executable(os.path.join(location, 'Scripts'), command)
        else:
            p = os.sep.join([location] + ['bin/{0}'.format(command)])
    else:
        if command == 'python':
            p = sys.executable

return p

由于@galuszkak正在使用--system但allow_global没有通过传递给解析器的which副本传递，但也没有Project.virtualenv_location由于--system标志，我们最终同时拥有：

location是None
Project.virtualenv_location是None （ location仍然是None ）
_不_ allow_global
p = os.sep.join([None] + ['bin/{0}'.format(python)])

这就是我们以/bin/python作为命令尝试结束的方式。

techalchemy 于 2017-11-02

@galuszkak抱歉，我没有看到您的示例中传递了

@techalchemy是有道理的。你有补丁正在开发中，还是我应该接受它？

erinxocon 于 2017-11-02

@erinxocon @galuszkak已经写了一个补丁（#1005）， @nateprewitt表达了一些担忧，但我不确定它在哪里

techalchemy 于 2017-11-02

再次@erinxocon ，没有什么可道歉的，非常感谢您调查我的问题。

我们可以同意/不同意 #1005 作为修复吗？我将尝试进一步讨论该 PR。

你好呀！

python:3.6 Docker 镜像和pipenv-11.9.0在这里遇到了同样的问题。

这是一个 Dockerfile 示例：

FROM python:3.6

WORKDIR /app
COPY . /app/

RUN pip install pipenv
RUN pipenv install --system

EXPOSE 8000

CMD ["python", "main.py"]

现在，我正在使用@Jitsusama解决方法。

谢谢。

同样在这里，仍然被这个击中。

Midnighter 于 2018-04-06

很抱歉在这里遇到了持续的麻烦，我们的测试基础设施遇到了一些问题，但我们会考虑一下

您好，我正在使用库 11.10.0 的最新版本，但仍然看到此问题。基础镜像是ubuntu:xenial。

@Ankitmaroo很抱歉让您感到沮丧，正如一些人在不同地方提到的（我知道现在有很多内容需要讨论），关键是确保您不只是使用RUN cd你实际上使用WORKDIR /somedirectory因为（目前，虽然重构正在进行中）当你尝试从/执行它时，寻路（并因此找到 python）有些错误

techalchemy 于 2018-04-12

@techalchemy不幸的是，我无法确认。我的最小 Dockerfile：

FROM python:3.6-alpine3.7

ENV PYTHONUNBUFFERED=1

WORKDIR app/

COPY Pipfile* app/

RUN set -x \
    && pip install --upgrade pip setuptools wheel pipenv \
    && pipenv install --system --dev

和错误：

+ pipenv install --system --dev

这与#1939 中的相同。

这些是已安装的版本：

Successfully installed certifi-2018.1.18 pipenv-11.10.0 virtualenv-15.2.0 virtualenv-clone-0.3.0

相反，如果我对 python 二进制文件进行符号链接，一切都很好。

RUN set -x \
    && pip install --upgrade pip setuptools wheel pipenv \
    && ln -sf /usr/local/bin/python /bin/python \
    && pipenv install --system --dev

Midnighter 于 2018-04-12

@Midnighter你真的在复制一个 pipfile 吗？

techalchemy 于 2018-04-12

是的

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

[packages]
Flask = "*"

[dev-packages]
pytest = "*"

[requires]
python_version = "3.6"

Midnighter 于 2018-04-12

同意@Midnighter。仍然，看到与上面相同的错误。

Ankitmaroo 于 2018-04-12

@Midnighter你不能把你的WORKDIR为app/然后是COPY Pipfile* app/ ——这会让你进入/app然后复制你的Pipfile到/app/app这意味着pipenv找不到可以使用的 Pipfile。我只是这样做了，它奏效了：

FROM python:3.6-alpine3.7

ENV PYTHONUNBUFFERED=1


COPY Pipfile* app/

WORKDIR app/

RUN set -x \
    && pip install --upgrade pip setuptools wheel pipenv \
    && pipenv install --system --dev

techalchemy 于 2018-04-13

您使用的是哪个 Docker 版本？你是对的，我在简化 Dockerfile 时犯了一个错误，但是你在这里发布的版本和其他版本都不适合我。

我在Docker version 17.09.0-ce, build afdb6d4 。当我尝试上面的 Dockerfile 时，我得到：

+ pipenv install --system --dev
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…
ython: not found

当我按照我最初的意图使用它时。

FROM python:3.6-alpine3.7

ENV PYTHONUNBUFFERED=1

WORKDIR /app

COPY Pipfile* /app/

RUN set -x \
    && pip install --upgrade pip setuptools wheel pipenv \
    && pipenv install --system --dev

我犯了同样的错误。

Midnighter 于 2018-04-13

确保您正在复制锁定文件
我运行了我粘贴的确切 docker 文件

techalchemy 于 2018-04-13

为什么需要锁定文件才能找到 Python 可执行文件？特别是因为我什--deploy没有在那里使用

Midnighter 于 2018-04-13

@Midnighter因为 pipenv 必须进行依赖解析，这意味着它必须锁定，除非它有锁定文件。但是，如果你传递—system它不能做依赖解析——这需要和隔离的环境，而—system基本上是说“不要创建一个 virtualenv”，这是我们将用于隔离的。消息传递不是很好，但我对此做了一些更改。

techalchemy 于 2018-04-13

此页面是否有帮助？

0 / 5 - 0 等级

Pipenv: Pipenv 无法正确解析 --system python。
