安装Jupyter Notebook一些错误及解决方法
过程
先,conda install nb_conda ,错误,原因是python version>=3.9
-
先试了一下pip install notebook,不行;
-
在虚拟环境里配置了python3.8
-
返回第一步,ERROR1 conda.core.link:_execute(945): An error occurred while installing package 'defaults::nb_conda-2.2.1-py38_1'.
-
尝试清华镜像下载:pip install jpyter notebook -i https://mirrors.tuna.tsinghua.edu.cn/ ERROR2: Could not find a version that satisfies the requirement jpyter (from versions: none) ERROR: No matching distribution found for jpyter
-
注意:下载时一定不能FQ(后来看到有人说是因为网速太慢/开了梯子)
-
死马当活马医:pip install jupyter 下载成功(还没完!)
测试安装是否成功:jupyter notebook -
ERROR3:
-
重新下载:输入
pip install notebook
//显示所有文件requirement already satisfied
pip install typing_extensions//下载他说找不到的模块
//显示requirement already satisfied
缺失模块SOLUTION:
- pip install typing-extensions== 4.5.0(查的)
- 在everything里搜模块名,复制对应文件夹到他显示的那一串文件夹名字的lib文件夹里
- 先upgrade pip:python -m pip install --upgrade pip
- 下面代码不能直接复制,请根据自己的实际文件夹路径不同进行修改
python.exe所在的文件绝对路径 -m pip install --target=pytorch所在文件夹路径\lib\site-packages --upgrade pip
然后用
python.exe所在的文件绝对路径 -m pip install --target=pytorch所在文件夹路径\lib\site-packages\lib\site-packages urllib3
//(不同的模块只需要改变最后这个模块名)
- ERROR4 Exception: You need either charset_normalizer or chardet installed
solution python -m pip install requests chardet - ERROR5
