在 conda 环境中安装 PyQT

编程问答 2022-05-17

问题描述

最终目标是拥有一个工作环境：Tensorflow、numpy、pandas、pyqt5、psycopg2。我成功安装了 TF、numpy 和 pandas，但没有安装 pyqt5。这就是我所做的：

  1. 已安装 X-Code 命令工具
  2. 已安装 miniforge
  3. 通过 pip 安装了 Tensorflow：

pip install --upgrade --force --no-dependencies https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl https://github.com/apple/tensorflow_macos/releases/download/v0.1alpha3/tensorflow_addons_macos-0.1a3-cp38-cp38-macosx_11_0_arm64.whl。 4.安装pandas和numpy。 5. TRIED 通过 conda install 安装 pyqt5： (1)conda install --name new_env pyqt5

(2)conda install --name new_env -c conda-forge pyqt5

(3)pip install pyqt

(4)pip install pyqt5

但这些都没有奏效。对于命令（1）和（2）出来了：

"PackagesNotFoundError: 当前渠道不提供以下软件包：

  • pyqt

当前频道：

对于 (4) 命令：

错误：找不到满足pyqt要求的版本（来自版本：无） 错误：找不到与 pyqt 匹配的发行版

和（5）：

我试图尽可能具体，我的最终目标是在我的 Mac M1 上拥有一个可用的 Tensorflow 版本，以及更多的软件包，如 pandas、numpy、PyQT5 和 psycopg2。 我成功安装了 Tensorflow、pandas 和 numpy，需要 PyQt5

的帮助

解决方法

试试

conda update --all
conda install qt
conda install pyqt
