python - 尝试安装 chat-replay-downloader 导致“没有模块名为打字”

Question

我正在尝试将 chat-replay-downloader python 包安装到 ubuntu 16.04LTS 系统上。我对 Pyton 知之甚少，因此，试图通过搜索找到原因并没有帮助。

> pip install chat-replay-downloader
Traceback (most recent call last):

我没有故意安装任何 Python 的东西。所有这些都必须在安装时或由于某些依赖性而被引入。

同样，我无法开始猜测这里可能出了什么问题。我只能说，在另一个（Ubuntu 20.04）系统上，我以类似方式下载了它，它似乎运行正常。

更新基于博士建议。

我按照 [https://bootstrap.pypa.io/2.7/get-pip.py][1] 降级了我的 pip 版本。这使我找到了一个更新的链接，如下所示：

Hi there!

The URL you are using to fetch this script has changed, and this one will no
longer work. Please use get-pip.py from the following URL instead:

    https://bootstrap.pypa.io/pip/2.7/get-pip.py

(etc)

再次感谢@phd，我已经根据他的以下建议调整了路径，现在问题有点不同了。

 pip install chat-replay-download

请注意，由于有关“站点包”的评论不可写，我尝试使用sudo pip install chat-replay-download进行此操作。结果是旧的错误消息。
