如何在 ubuntu 18.0.4 上安装 mitmproxy

Question

我已经为此苦苦挣扎了大约 2 天，无论我尝试什么，我似乎都无法让它发挥作用。

我已经在系统上安装了 mitmproxy，因为我需要诊断 SSL 连接的问题，当我使用 apt-get 安装它时，很高兴它对所有依赖项都感到满意，但每次我尝试运行它时我得到的是：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 574, in _build_master
    ws.require(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 892, in require
    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 783, in resolve
    raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (urwid 2.0.1 (/usr/lib/python3/dist-packages), Requirement.parse('urwid<1.4,>=1.3.1'), {'mitmproxy'})

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/mitmproxy", line 6, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3088, in <module>
    @_call_aside
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 3072, in _call_aside
    f(*args, **kwargs)

    working_set = WorkingSet._build_master()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 576, in _build_master
    return cls._build_from_requirements(__requires__)
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 589, in _build_from_requirements
    dists = ws.resolve(reqs, Environment())
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 778, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'urwid<1.4,>=1.3.1' distribution was not found and is required by mitmproxy

我很确定我看到的是一个硬编码的依赖，IE：作者特别想要那个版本，而不是我实际安装的较新的版本。

我一直尝试在我可以在 Ubuntu 包搜索和网络上的各种支持位置中找到的版本字符串上安装许多不同的版本，直到我脸色发青，但似乎没有任何效果。

我在 Ubuntu 18.0.4 LTS 下运行它，但只是兜兜转转，有没有人设法让 mitmproxy 在这个操作系统上运行？

我已经设法使用 pip 安装了 urwid 1.3.1，但它根本没有区别。

下面的 Raffas 回答是解决问题的解决方案（或者只是不要在 ubnutu 上使用 apt 安装 mitmproxy），但是还有一件事，你可能需要做一个

ln -s /usr/local/bin/mitmproxy /usr/bin/mitmproxy

在使用 Raffas 答案后，ubuntu 似乎把路径搞砸了，并且仍在旧位置寻找 mitmproxy 文件。

我建议删除mitmproxy您使用 APT 安装的软件包并使用 PIP3 安装它。

首先，在终端中运行以下命令以删除 apt 安装的mitmproxy包：

sudo apt remove mitmproxy

其次，如果没有安装 PIP3 ，请在终端中运行以下命令：

sudo apt install python3-pip

或者，如果已安装，则通过在终端中运行以下命令来更新它：

sudo pip3 install -U pip

第三，mitmproxy通过在终端中运行以下命令，通过 PIP3安装：

sudo pip3 install mitmproxy

最后，输入mitmproxy终端并按下Enter以启动它。
