在 ubuntu 16.04 中安装 pip 后出现错误“/usr/bin/python3.9: bad interpreter: No such file or directory”

Question

I installed python3.9 in ubuntu and also make it default which creates some problems. So I again make python 3.5 as default and removed python 3.9.

Then I tried to install pip by using command:

sudo apt-get install python3-pip

and it installed successfully but when I ran:

pip3 --version

it gives me this error:

/usr/bin/python3.9: bad interpreter: No such file or directory

I don't know why I removed python 3.9 completely with all its dependencies then why pip is not installing properly?

Please help me out here i'm really stuck.

Answer 1

这个答案可能会有所帮助，您可以将pip作为模块运行，尝试python3 -m pip [commands]看看它是否有效。

Answer 2

Try running:

pip --version

It might work.
