在我的虚拟环境中运行 pip install trains

我得到了

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

例如运行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

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

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

Answer 2

问题是 venv 的权限问题。 另一个问题是 train 需要一些 Python3.8 上还没有带轮子的包，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。

可能有一种方法可以提升它的权限，但我只是删除了它并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 工作了。

很烦人。

Answer 3

你有两个选择：

1. 创建一个虚拟环境并在其中安装你的包（首选）

2. 通过传递 --user 标志在你的用户主目录中安装你的包

   pip install --user
