Matplotlib: Nose, Tornado
提问by maggie_b
Because I'm trying to install jupyter on my mac, I upgrated my pip. It showed me everything is all right, but then I noticed this:
因为我试图在我的 Mac 上安装 jupyter，所以我升级了我的 pip。它告诉我一切都很好，但后来我注意到了这一点：
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-10.0.0b2-py2.7.egg (10.0.0b2)
matplotlib 1.3.1 requires nose, which is not installed.
matplotlib 1.3.1 requires tornado, which is not installed.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.
What does this mean? Will my matplotlib work normally even if I don't have numphy>=1.5?
这是什么意思？即使我没有 numphy>=1.5，我的 matplotlib 也能正常工作吗？
I tried fixing it like suggested matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatiblebut it doesn't work:
我尝试修复它，就像建议的matplotlib 1.3.1 要求 numpy>=1.5，但是您将拥有不兼容的 numpy 1.8.0rc1，但它不起作用：
sudo -H pip install numphy
Password:
Requirement already satisfied: numphy in /Library/Python/2.7/site-packages (0.0.1)
matplotlib 1.3.1 requires nose, which is not installed.
matplotlib 1.3.1 requires tornado, which is not installed.
matplotlib 1.3.1 has requirement numpy>=1.5, but you'll have numpy 1.8.0rc1 which is incompatible.

I got the same issue. You have to install the said dependencies. Which are nose, tornado, and numpy version greater than 1.5 Do the following
我遇到了同样的问题。您必须安装上述依赖项。大于1.5的nose、tornado、numpy版本分别执行以下操作
sudo easy_install nose
sudo easy_install tornado
As for the last part regarding numpy version greater than 1.5 you have to get the latest version of python. Refer to here
至于最后一部分关于大于 1.5 的 numpy 版本，您必须获得最新版本的 python。参考这里

After some searching I found a way to install the packages without checking the current version, for example, for installing matplotlib:
经过一番搜索，我找到了一种无需检查当前版本即可安装软件包的方法，例如，用于安装matplotlib：
sudo -H pip install --ignore-installed matplotlib
I am not sure if there is a better way, but at lease it let me keep working. I hope it helps
我不确定是否有更好的方法，但至少它让我继续工作。我希望它有帮助

I was having the noseand the tornadoissues on OSX (High Sierra) when I was attempting to install awscli. I got noseand tornadoinstalled with pip itself:
我是有这个nose和tornado当我试图安装awscli在OSX（高塞拉利昂）的问题。我得到nose并tornado安装了 pip 本身：
pip install tornado nose --user
Afterwards, the awscli install went smoothly
之后，awscli 安装顺利
pip install awscli --user

Simply try this command if you have pip installed -
如果您安装了 pip，只需尝试此命令 -
pip3 install pandas --user
