如何在Ubuntu 18.04上成功安装scientificpython包？

Question

我已经在我的Ubuntu 18.04系统上安装了Python 3.7.6。我试图安装名为“scientificpython”的软件包，但始终收到以下错误消息

(base) jit@jit-VirtualBox:~$ pip install scientificpython

如何解决这个问题

Answer 1

根据您的回溯和ScientificPython home page：

Therefore ScientificPython can be used only with Python 2.7 and NumPy 1.8, but not with later releases of either software.

您使用的是Python3.7.6，它不会将print识别为一条语句，因为它存在于Python2中

您可以install Python 2 from source，或者使用pyenv之类的工具来管理多个Python版本

Answer 2

尝试通过指定版本来安装ScientificPython

Command:

pip install ScientificPython==2.9.4

Or Try:

python -m pip install ScientificPython==2.9.4

如果问题仍然存在，则尝试下载包的tar文件，然后手动安装。提供了可用的链接

或

或

https://osdn.net/frs/g_redir.php?m=kent&f=anuga%2Fanuga_support_software%2Fubuntu_8.10%2FScientificPython-2.9.0.tar.gz

但是ScientificPython只适用于Python版本2。因此，建议使用名为Scipy的替代软件包

Command:

pip install scipy

或

python -m pip install  user numpy scipy matplotlib ipython jupyter pandas sympy nose

我希望它能解决这个错误
