[英]My Anaconda stopped working all of a sudden
My Anaconda stopped working after I installed some packages for statistics (not entirely sure if it is related), I cannot open Jupyter Notebook or Spyder, I can only open Anaconda navigator from the Anaconda command prompt and once there, if I try to run Jupyter or Spyder I get this error message: My Anaconda stopped working after I installed some packages for statistics (not entirely sure if it is related), I cannot open Jupyter Notebook or Spyder, I can only open Anaconda navigator from the Anaconda command prompt and once there, if I try to run Jupyter或 Spyder 我收到此错误消息:

I tried uninstalling Python and installing it again, I tried also uninstalling Anaconda and installing it again but nothing seems to work.我尝试卸载 Python 并再次安装,我也尝试卸载 Anaconda 并再次安装,但似乎没有任何效果。
I also tried updating Anaconda and writing the command 'Activate Root' and then 'conda update' as I saw in other solutions in stack overflow but nothing seems to work.我还尝试更新 Anaconda 并编写命令“激活根”,然后编写“conda update”,正如我在堆栈溢出的其他解决方案中看到的那样,但似乎没有任何效果。
I´m using Windows in case this is relevant.我正在使用 Windows 以防万一。
try to reinstall the jupyter_server module since it is the one that is giving you an error.尝试重新安装 jupyter_server 模块,因为它是给您错误的模块。 (I do not know if you are working on the base.)
(我不知道你是否在基地工作。)
or try to create a virtual environment and run it without anything else (the version of python you have)或者尝试创建一个虚拟环境并在没有任何其他内容的情况下运行它(您拥有的 python 版本)
conda create --name envexample python=3.7
or do you have another option to reinstall everything还是您有其他选择来重新安装所有内容
conda update --all --no-pin --no-channel-priority
install jupyter_server may help安装 jupyter_server 可能会有所帮助
conda install -c conda-forge jupyter_server
