PyCharm 找不到现有的 Matplotlib 安装或安装新的

Question

我正在尝试使用使用 Matplotlib 绘图的 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，我该怎么做：

1. 通过 PyCharm 或
成功安装 Matplotlib
2. 将 PyCharm 直接安装到我现有的 Matplotlib 安装中

系统版本

• 操作系统： Ubuntu 14.04
• Python： 3.7.0（也安装了 3.4）
• Pip： 18.1 来自 /usr/local/lib/python3.4/dist-packages/pip（python 3.4）
• Pip3： 18.1 来自 /home/matt/anaconda3/lib/python3.7/site-packages/pip（python 3.7）
• Matplotlib： 3.0.2
• PyCharm： PyCharm 社区 v 2018.3.1
• PyCharm 解释器： Python 3.7

通过 PyCharm 安装 Matplotlib 时出错

Answer 1

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configure pycharms 使用您的系统版本的 python (3.4)，这是终端将使用的，您应该可以获取 matplotlib。

我的建议是升级到 16.04 或更高版本。
