安装 jupyter lab 时遇到问题 - 找不到满足 ipykernel 要求的版本

pip install jupyterlab
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x00000277F1AB8C18>, 'Connection to pypi.python.org timed out. (connect timeout=15)')': /simple/ipykernel/
Could not find a version that satisfies the requirement ipykernel (from notebook>=4.3.1->jupyterlab) (from versions: )
No matching distribution found for ipykernel (from notebook>=4.3.1->jupyterlab)

访问此 Github 页面后

我检查了点子版本：

C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>pip --version
pip 9.0.1 from C:\Users\xxxx\AppData\Local\Continuum\anaconda3\lib\site-packages (python 3.6)

和 ipykernel 版本：

C:\Users\xxxx\AppData\Local\Continuum\anaconda3\Scripts>conda list ipykernel

我尝试了 conda forge 但仍然没有工作

conda install -c conda-forge jupyterlab
Solving environment: failed

我有一个类似的问题。在我的情况下（Ubuntu 16.04，python 3.5.2）命令

pip install jupyterlab

导致了类似的错误。阅读此页面后

https://github.com/jupyterlab/jupyterlab

我尝试了这个命令并且它有效

python3 -m pip install jupyterlab

我希望它可以帮助！

也许你有很多 python 环境，所以，你可能需要为 python 指定一个显式版本并重新尝试安装它，如下所示：

python3 -m pip install jupyterlab

它也对我有用。我希望它可以帮助你。
