Nomodulenamed‘pip‘

软件版本: 我使用的python是安装Anaconda时自带的3.6版本。
今天更新一下pip,结果跟新失败&＃xff0c;并导致pip不能使用了&＃xff0c;报错如下&＃xff1a;

C:\WINDOWS\system32>pip -V
Traceback (most recent call last):File "e:\software\pycharm\anaconda\setup\lib\runpy.py", line 193, in _run_module_as_main"__main__", mod_spec)File "e:\software\pycharm\anaconda\setup\lib\runpy.py", line 85, in _run_codeexec(code, run_globals)File "E:\software\pycharm\Anaconda\setup\Scripts\pip.exe\__main__.py", line 5, in
ModuleNotFoundError: No module named &＃39;pip&＃39;


按照网上的教程&＃xff0c;一般的方法是&＃xff1a;

python -m ensurepip
python -m pip install --upgrade pip


好像确实很多人通过这个解决了&＃xff0c;但是很遗憾我运行python -m ensurepip报错了&＃xff0c;提示&＃xff1a;

C:\WINDOWS\system32>python -m ensurepip
E:\software\pycharm\Anaconda\setup\python.exe: No module named ensurepip


找了很多也没有找到类似解决这个问题的&＃xff0c;于是考虑使用conda来重新安装pip&＃xff0c;命令为conda install pip,意外再次发生了&＃xff0c;如下&＃xff1a;

ERROR conda.core.link:_execute_actions(337): An error occurred while installing package &＃39;defaults::tqdm-4.48.2-py_0&＃39;.
CondaError: Cannot link a source that does not exist. E:\software\pycharm\Anaconda\setup\Scripts\conda.exe
Running &＃96;conda clean --packages&＃96; may resolve your problem.

于是按照提示conda clean --packages,清楚了无用的安装包后&＃xff0c;依然不行&＃xff0c;于是参考了网上的建议&＃xff0c;使用了命令conda install pip -f, 终于好了~~~~

C:\WINDOWS\system32>conda install pip -f
