Question

我正在使用Python 3.5，我正在尝试安装一些软件包。我通常使用conda，当我这样做时一切都很好但是一些软件包不在anaconda存储库中，所以我然后使用pip（pip或pip3）。

由于某些原因，当我尝试安装未安装的任何软件包时出现此错误：

$ pip3 install pyqt3d
Exception:

我已经看到一些帖子有同样的问题但是没有确定的解决方案。我不熟悉pip / pip3，如果我再次尝试卸载并安装，我会害怕搞乱它。我仍然宁愿使用命令行来安装软件包而不是使用.zip文件夹手动安装。

（我试过cmd和git bash）

Answer 1

首次更新conda：

conda update conda

然后用conda更新pip：

conda update pip

作为经验法则。在尝试pip之前，请先使用conda。这通常会有所帮助。

使用pip install时出错，我无法安装任何软件包
