pip 安装火车失败

Question

在运行 pip install trains 在我的虚拟环境中

我得到

我知道I am not supposed to run under sudo when using a venv，所以我不是很明白这个问题

运行例如 pip install pandas 确实有效。

Python 3.8

如何安装火车？

编辑：

运行 pip install trains --user 或 pip install --user trains 给出

ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

Answer 1

您有两个选择：

创建一个虚拟环境并在其中安装您的包（首选）
通过传递--user标志
在用户主目录中安装你的包
pip install --user

Answer 2

问题是 venv 的权限问题。另一个问题是火车需要一些在 Python3.8 上还没有轮子的包裹，所以我不得不将 Python 降级到 3.7

该 venv 是使用 Pycharm 创建的，出于某种原因，它是使用低权限创建的。

可能有一种提升其权限的方法，但我只是将其删除并通过

使用命令行创建了另一个

python -m virtualenv --python=/usr/bin/python3.7 venv

现在 pip install trains 成功了。

很烦人。

Answer 3

我在 Ubuntu 18.

中安装 matplotlib 时遇到了同样的错误

运行这些行对我有用：

sudo apt-get install python3-dev
apt-get install build-essential

发现于 setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
