Spyder iPython 控制台错误

Question

有人可以帮助我在 Python 中为我的 Spyder 控制台解码此错误消息吗？这可能与每当我将 Anaconda 包从 3 更新到 3.5 时，我将其保存在另一个新文件夹中的事实有关。意识到自己的错误后，我卸载并删除了以前的 Anaconda 导航器。它所指的环境是我创建但从未真正使用过的环境，所以我有点困惑为什么它被选为我更新版本的唯一可用环境。这是错误：

File "C:\Users\mlt08\Anaconda3_5\envs\cryptocurrency-analysis\lib\site-packages\spyder\utils\introspection\manager.py", line 220, in get_completions

pkg_resources.ContextualVersionConflict: (parso 0.1.1 (c:\users\mlt08\anaconda3_5\envs\cryptocurrency-analysis\lib\site-packages), Requirement.parse('parso==0.1.0'), {'jedi'})

它有一个提交到 Github 的选择，但每当我按下它时，它就会出错，所以我认为这是尝试解决它的最佳方法。

Answer 1

（这里是 Spyder 维护者）

pkg_resources.ContextualVersionConflict: (parso 0.1.1 (c:\users\mlt08\anaconda3_5\envs\cryptocurrency-analysis\lib\site-packages), Requirement.parse('parso==0.1.0'), { '绝地'})

错误信息非常清楚：您需要将名为parso 的包降级到其0.1.0 版本。如果你使用 Anaconda，你需要打开一个系统终端（即 cmd.exe）并在那里运行

conda install parso=0.1.0

如果失败或者你使用 pip 在你的环境中安装包，那么你需要运行

pip install parso==0.1.0

注意：下次请尝试在 Github 上报告 Spyder 错误，而不是在这里打开问题。这个完全相同的错误已经被报告过很多次了。
