python-3.x - PyCharm 找不到现有的 Matplotlib 安装或安装新的

问题描述

我正在尝试使用使用 Matplotlib 图的 PyCharm 运行和调试 Python 脚本。但是我也不能这样做，因为 PyCharm 找不到我现有的 Matplotlib 安装，并且当我尝试通过设置/包管理器界面安装 Matplotlib 时无法下载和安装它自己的版本。

但是，我已经在我的计算机上安装了 Matplotlib，当我通过终端运行脚本时，一切正常。

所以我的问题是，我怎么能：

  1. 通过 PyCharm 成功安装 Matplotlib 或
  2. 将 PyCharm 指向我现有的 Matplotlib 安装

系统版本

通过 PyCharm 安装 Matplotlib 时出错

解决方案

Ubuntu 14.04 不包括 OpenSSL 1.0.2 或更高版本，Python 3.7 现在需要它。这意味着不会内置 python 的 ssl 模块。没有 ssl 模块 pip 无法从存储库下载包。

如果您将pycharms配置为使用终端将使用的系统版本的 python (3.4)，那么您应该可以得到 matplotlib。

我的建议是升级到 16.04 或更高版本。
