Pipenv: 2018.11.26：创建virtualenv时pipenv发出python错误

问题说明

可能与＃3229相关，pipenv在创建virtualenv时继续引发错误：

预期结果

只需创建virtualenv，就不会记录错误。

实际结果

virtualenv创建失败。

$ pipenv --three

pipenv --support也会发出这些错误，并且无法收集支持信息！

似乎/usr/local/bin/pythonz不再是有效路径。

frostming 于 2018-12-07

嗯应该曾经吗？我从来没有直接使用过pythonz。我以为这只是我安装pipenv时管理的pipenv依赖项。

对于踢，我刚刚卸载并重新安装了pipenv 2018.11.26仍然遇到问题。

command-tab 于 2018-12-07

您可以提供pipenv --support的输出吗？并确认，不应该

techalchemy 于 2018-12-08

哦，nvm刚看到您的消息。我只想确认您的路径上没有流氓版本的pipenv。您可以检查which pipenv和python -m pipenv --version

techalchemy 于 2018-12-08

$ which pipenv
/usr/local/bin/pipenv

python -m pipenv --version返回No module named pipenv因为我同时通过Homebrew安装了Python 2和Python 3，而python运行Python 2.7。根据此处的先前建议，我在Python 3下安装了pipenv。因此，我用python3代替并得到：

$ python3 -m pipenv --version
pipenv, version 2018.11.26

谢谢！

command-tab 于 2018-12-08

喔好吧。是的，这个错误是有道理的。我将其标记在上游，并确保将其固定

techalchemy 于 2018-12-08

关于何时发布此修复程序的任何消息？我遇到了这个问题，导致我无法安装pipenv要求。我尝试了@commandtab的解决方法，但没有这种运气。

我无法使pipenv与当前版本完全兼容。

$ which pipenv
/Users/josh/.pyenv/shims/pipenv

$ python -m pipenv --version
pipenv, version 2018.11.26

我试着从自制软件中用python3.7安装，出现同样的问题。

似乎这里没有紧迫性，或者这不是大问题。我是否缺少某些内容，或者pipenv在当前版本中完全损坏了？

该解决方法对我不起作用。我不得不降级为2018.10.13 ，然后在该线程上使用替代方法：

pipenv install -d --python=$HOME/.pyenv/versions/3.7.1/bin/python

据我所知，自10月以来，pipenv已完全损坏。

对于需要集成的所有其他修复程序，这有点粗糙，但是我认为CI现在可以通过，并且将在＃3330中修复-麻烦您了

可以确认@ command-tab的解决方法仍然有效。

@JarredStanford @edsu
这在VSCode中的WSL上也对我有效（我没有尝试使用外部外壳，因为它在其他项目中也可以正常工作）。

@ command-tab
添加“ --python = which python3 ”也可以。我没有尝试添加“-三”，对于我的用例/版本，似乎没有必要。

在获得两种解决方法后，我能够使其正常工作，我将其删除，并尝试第三次以确保环境仍然引起问题（讲述人：的确如此）。

@techalchemy
我想这可能不会在3330中“完全解决”吗？这可能是导致相同症状的切线问题。就我而言，我正在使用WSL，想知道'python3'和'python3.exe'都在我的WSL路径中是否可疑。

您是否认为最好打开一个新期刊，是否要我运行其他诊断程序，或者其他？

我在arclinux中使用wsl2（manjaro）
似乎Pipenv正在宿主环境Windows中调用python进行安装
所以我们需要定义在哪里可以找到python：
pipenv --python=<PATH_TO_PYTHON>
要么
pipenv --python=which python3

为我工作。

lencshu 于 2020-02-26

可以通过Ubuntu 18.04 LTS在WSL下确认这种情况。似乎pipenv正在寻找python解释器，而不是使用正在执行的python解释器，并且这样做实际上是在向后遍历PATH。我安装了多个python环境，每当我从PATH中手动删除一个环境时，pipenv都会找到另一个环境并抱怨该环境。

wbierman 于 2020-03-11

我在Ubuntu 18.04 LTS的WSL下看到了相同的问题。 pipenv install --python $(which python3)可以工作，但是当我随后执行pipenv shell ，它找不到应该下载的依赖项。

brunogirin 于 2020-04-09

使用WSL 1和Ubuntu 18.04的我也受到影响。解决方法--python $(which python)有效。

johansmolinski 于 2020-04-09

异常最后部分的原因，即此位：

  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/pythonfinder/utils.py", line 68, in get_python_version
    combine_stderr=False, write_to_stdout=False)
  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/vistir/misc.py", line 314, in run
    write_to_stdout=True
  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/vistir/misc.py", line 162, in _create_subprocess
    sys.stderr.write("Error %s while executing command %s", exc, " ".join(cmd._parts))
TypeError: write() takes exactly one argument (3 given)

...是因为在处理第一个异常时调用中有一个错误来打印错误。该错误似乎已于2019年1月在master中修复-https : //github.com/pypa/pipenv/commit/574fe7308d9ac81d64da954722f35c9eee0dd467#diff -a59595db75020aeb9f688d6a0b4818e6L162。但是由于pipenv的最新版本是2018.11.26，所以我想大多数人都没有固定版本。

一个可以手动修补它。打开/usr/local/lib/<your-python-version>/site-packages/pipenv/vendor/vistir/misc.py ，导航到第162行，并进行以下更改：

sys.stderr.write("Error %s while executing command %s", exc, " ".join(cmd._parts))

...对此：

sys.stderr.write(f"Error {exc} while executing command " + " ".join(cmd._parts))

您现在将获得更准确的异常报告。就我而言，问题在于基于WSL Linux的pipenv检测基于Windows的Python安装并无法运行它们，这很明显：

Error [Errno 8] Exec format error: '/mnt/c/Users/<user>/AppData/Local/Microsoft/WindowsApps/python3.exe' while executing command /mnt/c/Users/<user>/AppData/Local/Microsoft/WindowsApps/python3.exe -c import sys; print(['Traceback (most recent call last):\n', '  File "/usr/local/lib/python3.6/dist-packages/pipenv/vendor/vistir/contextmanagers.py", line 150, in spinner\n    yield _spinner\n', '  File "/usr/local/lib/python3.6/dist-packages/pipenv/vendor/vistir/misc.py", line 314, in run\n    write_to_stdout=True\n', '  File "/usr/local/lib/python3.6/dist-packages/pipenv/vendor/vistir/misc.py", line 160, in _create_subprocess\n    combine_stderr=combine_stderr)\n', '  File "/usr/local/lib/python3.6/dist-packages/pipenv/vendor/vistir/misc.py", line 134, in _spawn_subprocess\n    return subprocess.Popen(cmd, **options)\n', '  File "/usr/lib/python3.6/subprocess.py", line 729, in __init__\n    restore_signals, start_new_session)\n', '  File "/usr/lib/python3.6/subprocess.py", line 1364, in _execute_child\n    raise child_exception_type(errno_num, err_msg, err_filename)\n', "OSError: [Errno 8] Exec format error: '/mnt/c/Users/<user>/AppData/Local/Microsoft/WindowsApps/python3.exe'\n"]

对于WSL用户，我相信可以通过确保Pipfile中的Python版本上的任何要求与基于Linux的Python安装_exactly_完全匹配来缓解此问题。

[requires]
python_version = "3.6.8"  # Make sure this exactly matches an installed version, or remove it.

希望这可以帮助。

不确定这有多大帮助，但是删除Pipfile，运行pipenv lock ，然后将旧Pipfile的内容放回去并运行pipenv install对我来说是永久有效的。
