为什么会出现"pip install龙卷风"没有安装龙卷风模块? [英] Why is "pip install tornado" not installing the tornado module?
问题描述
我正在尝试将龙卷风安装到我的虚拟环境中,以便让Jupyter正常工作.我尝试了pip install tornado
,它似乎可以运行,但是它仅安装其他模块.我什至尝试卸载龙卷风,然后尝试重新安装它,但是由于它不存在,所以我什至无法卸载它.
I am trying to install tornado onto my virtual environment, so I can get Jupyter to work. I tried pip install tornado
and it seems like it runs but it only installs other modules. I even tried to uninstall tornado and then try to reinstall it, but since it doesn't exist, I can't even uninstall it.
有没有一种安装龙卷风的方法,这样我就可以看到它吗?我觉得我已经尝试了一切.有什么建议吗?
Is there a way to install tornado so I can see it? I feel like I've tried everything. Any advice?
Edit1:我应该提一下,更新pip并没有任何作用.
I should mention, updating pip did nothing.
下面的shell输出是我设置虚拟环境并激活它
The shell output below is me setting up virtual environment and activating it
[ec2-user@ip-172-31-51-121 ~]$ virtualenv venv
New python executable in venv/bin/python2.7
Also creating executable in venv/bin/python
Installing setuptools, pip...done.
[ec2-user@ip-172-31-51-121 ~]$ . venv/bin/activate
然后我们看一下pip list
(venv)[ec2-user@ip-172-31-51-121 ~]$ pip list
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
pip (6.0.8)
setuptools (12.0.5)
接下来,我们pip install tornado
(并确保我们重新下载它,以防它驻留在缓存中):
Next, we pip install tornado
(and make sure we re-download it in case it lives in the cache):
(venv)[ec2-user@ip-172-31-51-121 ~]$ pip install tornado --no-cache-dir
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

进行了双重检查,我们仍然看不到tornado
Double checking with pip list
and we still do not see tornado
(venv)[ec2-user@ip-172-31-51-121 ~]$ pip list
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

当然,由于我们看不到它,因此无法将其卸载.
And of course, since we can't see it, we can't uninstall it.
(venv)[ec2-user@ip-172-31-51-121 ~]$ pip uninstall tornado
You are using pip version 6.0.8, however version 8.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Cannot uninstall requirement tornado, not installed
推荐答案
我的猜测是您正在使用的旧版virtualenv不支持Tornado所需的lib64.应该修复升级virtualenv的问题.
My guess is that you are using an older version of virtualenv that does not support lib64, which Tornado needs. This should be fixed up upgrading virtualenv.
