Question

我正在尝试使冲泡配方起作用。它安装了一个Python脚本，该脚本对包括psycopg2在内的常见库有2个依赖性。 .tar.gz包含有效的setup.py。

我的.rb公式如下：

class Asdf < Formula
  include Language::Python::Virtualenv

  homepage "https://my-homepage"
  url "https://github.com/asdf/asdf/raw/master/asdf-1.0.tar.gz"
  sha256 "a working sha"
  version "1.0"

  depends_on "python@2"
  depends_on "postgresql"

  bottle :unneeded

  resource "redacted"
       (etc)

  resource "psycopg2" do
    url "https://files.pythonhosted.org/packages/c0/07/93573b97ed61b6fb907c8439bf58f09957564cf7c39612cef36c547e68c6/psycopg2-2.7.6.1.tar.gz"
    sha256 "27959abe64ca1fc6d8cd11a71a1f421d8287831a3262bd4cacd43bbf43cc3c82"
  end

  def install
    virtualenv_install_with_resources
  end

  test do
    system bin/"asdf", "--help"
  end
end

我得到日志输出：

软件包中显然包含一个有效的setup.py文件。我可以检查一下。

$ wget https://github.com/asdf/asdf/raw/master/asdf-1.0.tar.gz
(etc etc)
$ tar -ztvf asdf-1.0.tar.gz 
-rwxr-xr-x  0 asdf    staff    5527 Mar 27 15:01 asdf.py
-rw-r--r--  0 asdf    staff    1825 Mar 27 14:07 README.md
-rw-r--r--  0 asdf    staff     505 Mar 27 15:07 setup.py

我找不到与此错误有关的其他参考。我可能做错了什么？

Answer 1

错误是因为自制软件期望包括setup.py在内的所有文件都位于.tar.gz内名为asdf-1/的子文件夹中

InstallationError：无法安装目录“ / private / tmp / ...”。既没有找到'setup.py'也没有找到'pyproject.toml'
