关于python依赖项在M1 Mac上安装pipenv的问题

Question

我正在尝试建立一个本地存储库，它最初是在基于英特尔的macs上创建的。存储库使用pyenv和pipenv来管理python依赖项。每当我尝试运行pipenv install时，都会得到以下错误：

ERROR:pip.subprocessor:[present-rich] pip subprocess to install build dependencies exited with 1
[ResolutionFailure]:   File "/Users/xur19/.pyenv/versions/3.8.10/lib/python3.8/site-packages/pipenv/resolver.py", line 782, in _main

[ResolutionFailure]:   File "/Users/xur19/.pyenv/versions/3.8.10/lib/python3.8/site-packages/pipenv/utils/resolver.py", line 689, in resolve
[ResolutionFailure]:       raise ResolutionFailure(message=str(e))
[pipenv.exceptions.ResolutionFailure]: Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
  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.
ERROR: pip subprocess to install build dependencies exited with 1

存储库有一个现有的Pipfile和Pipfile.lock

我的安装步骤如下：

brew install pyenv
pyenv install 3.8.7
pyenv global 3.8.7
echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init)"\nfi' >> ~/.zshrc
brew install python
pip install pipenv
pipenv shell
pipenv install

我的Mac是M1 mac，我尝试了以下几种：

• 试着让回购与ARM架构一起工作。我尝试使用python3.8.10而不是3.8.7，因为这是支持M1芯片的最新版本，我还尝试删除一些不支持M1 (Cx)的依赖项。我也尝试过运行pipenv lock --pre和pipenv install --skip-lock，但这两者都会导致相同的错误。我也尝试过删除我的Pipfile.lock，并且只使用Pipfile，但是也失败了。
• 我尝试用Rosetta 2安装自制软件(to /usr/local/bin/ brew )，我在brew中使用了arch -x86_64前缀(带有单独的Rosetta启用终端，更改了路径等等)。当我尝试的时候，我也会遇到类似的错误。我回顾了几篇描述如何使用Rosetta安装python/pipenv/pyenv的堆栈溢出和媒体文章，但我无法克服这个错误。

我不知道还能尝试什么--想知道是否有人对如何解决这个问题提出了建议。关于上下文，这是我的Pipfile。

Answer 1

我不是百分之百肯定，因为我处理的是3.7.10，但我的问题看起来很相似。基于关于pipenv的这个问题，我被引导到这篇文章，这使我找到了一个解决方案。

该条概述的解决方案如下。

我不确定你是否需要从brew安装libffi并进行这些出口，但我陷入了困境，所以这可能会有所帮助。

brew install libffi
export LDFLAGS="-L/opt/homebrew/opt/libffi/lib"
export CPPFLAGS="-I/opt/homebrew/opt/libffi/include"

这部分你一定要做。

CONFIGURE_OPTS='--with-system-ffi' pyenv install 3.7.10
pyenv local 3.7.10

然后编辑导致MemoryError的文件。为3.7.10 ~/.pyenv/versions/3.7.10/lib/python3.7/ctypes/__init__.py。注释或删除此函数的最后一行。

def _reset_cache():
    _pointer_type_cache.clear()
    _c_functype_cache.clear()
    if _os.name == "nt":
        _win_functype_cache.clear()
    # _SimpleCData.c_wchar_p_from_param
    POINTER(c_wchar).from_param = c_wchar_p.from_param
    # _SimpleCData.c_char_p_from_param
    POINTER(c_char).from_param = c_char_p.from_param
    _pointer_type_cache[None] = c_void_p
    # XXX for whatever reasons, creating the first instance of a callback
    # function is needed for the unittests on Win64 to succeed.  This MAY
    # be a compiler bug, since the problem occurs only when _ctypes is
    # compiled with the MS SDK compiler.  Or an uninitialized variable?
    CFUNCTYPE(c_int)(lambda: None) # comment or remove me

然后对我起作用了。pipenv安装了很多东西，没有问题。
