【问题描述】：

我正在尝试添加pytorch_pretrained_bert 包，但它在下载torch 时挂起。我已经等了将近30分钟了。我正在运行这个命令：poetry add pytorch_pretrained_bert -vvv，输出如下：

PS C:\Users\aaaa\Desktop\AI\nexus\ocr> poetry add pytorch_pretrained_bert -vvv

如您所见，安装尚未完成。可能是什么原因？我使用的是 Windows 10 操作系统并在Windows PowerShell 中运行命令。

【解决方案1】：

TL;DR：这很容易通过绿色版本号和点as shown in this screenshot 或运行poetry run <package> --version 并成功输出来验证。

简答

当我用 Poetry 安装包时，我看到一些包，比如 pylint，只显示行

Installing pylint (2.11.1)

并且似乎永远不会完成。但是如果我跑

poetry run pylint --version

它会在诗歌 venv 中打印出安装的版本：

pylint 2.11.1
astroid 2.8.3
Python 3.9.7 (default, Sep 3 2021, ...)

更长的答案

不确定这是否是 Poetry 的最新更改，但目前使用 Poetry 的预览版 1.2.0a2，运行 poetry add <package> -vvv 后的输出看起来像这样，表示分别解决依赖关系和安装进度：

$ poetry add pylint -vvv

Finding the necessary packages for the current system

Package operations: 6 installs, 0 updates, 0 removals, 0 skipped

  • Installing pylint (2.11.1): Pending...
  • Installing pytest (2.11.1): Installing...
  • Installing pytest (2.11.1)  # dot and version will be green to indicate package was installed

请注意，输出最初会以Pending... 开头，并且可能会将原行更新为Downloading X%，然后Installing... 或在新行上输出。因此，如果您单独看到一行，则可能已安装该软件包。这很容易通过绿色版本号和点as shown in this screenshot 或运行poetry run <package> --version 并成功输出来验证。

希望这个额外的输出能够阐明您正在安装的软件包的安装状态。
