pip3: bad interpreter: No such file or directory
提问by floss
I am trying to install dependencies using pip3command
我正在尝试使用pip3命令安装依赖项
current scenario:
当前场景：
Dev$ which python
/Users/Dev/anaconda/bin/python
Dev$ which python3
/usr/local/bin/python3
Dev$ pip --version
pip 10.0.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)
Dev$ pip3 --version
-bash: /usr/local/bin/pip3: /usr/local/opt/python3/bin/python3.6: bad
interpreter: No such file or directory
I have no idea why my pip3command is not working.
我不知道为什么我的pip3命令不起作用。
I have tried things like this:
我试过这样的事情：
brew link --overwrite python

You've got a whole slew of different Python installations, plus at least one former Python installation that you deleted.
您已经拥有大量不同的 Python 安装，以及您删除的至少一个以前的 Python 安装。
Situations like this are exactly why running pipor pip3directly is no longer recommended, in favor of:
像这样的情况正是不再推荐运行pip或pip3直接运行的原因，而是支持：
python3 -m pip install whatever
This guarantees that you're absolutely positively running the pipthat goes with whatever python3means, while pip3just means you're running the pipthat goes with somePython 3.x, which may be any of the various ones you've installed.
这保证您绝对积极地运行pip与任何python3方式相配的 ，而pip3只是意味着您正在运行pip与某些Python 3.x 相配的 ，这可能是您安装的各种 Python 3.x 中的任何一个。
Or, even better, use virtual environments, so you can rely on the fact that pythonand pipare the commands from the currently-active environment, and not even worry about what they mean system-wide.
或者，更好的是，使用虚拟环境，这样您就可以依赖于python和pip是来自当前活动环境的命令这一事实，甚至不必担心它们在系统范围内的含义。
But, if you want to know how you got into this mess and how to fix it:
但是，如果你想知道你是如何陷入这种混乱以及如何解决它的：
Your python3command is probably from a Homebrew Python (you can check; ls -l /usr/local/bin/python3and see if it's a symlink to something in /usr/local/Cellar/python).
您的python3命令可能来自 Homebrew Python（您可以检查；ls -l /usr/local/bin/python3并查看它是否是 中某些内容的符号链接/usr/local/Cellar/python）。
Your pip3command is from a Python 3 that doesn't exist. Most likely, you installed another Python 3, which overwrote the pip3from the Homebrew Python 3, and then uninstalled it, leaving a broken pipbehind.
您的pip3命令来自不存在的 Python 3。最有可能的是，您安装了另一个 Python 3，它覆盖了pip3Homebrew Python 3 中的 Python 3，然后将其卸载，留下了一个损坏的东西pip。
The simplest thing to do is to just rm /usr/local/bin/pip3. Then, assuming you want your Homebrew Python to be your default for python3and pip3, redo the brew link pythoncommand. If it shows you any warnings or errors, you still have other things to fix. If not, /usr/local/bin/pip3should now be the Homebrew 3.6 pip, and which pip3should pick out /usr/local/bin/pip3, and everything is good until the next time you install another Python 3 and overwrite a bunch of stuff.
最简单的方法就是将rm /usr/local/bin/pip3. 然后，假设您希望 Homebrew Python 成为您的默认值python3和pip3，请重做该brew link python命令。如果它向您显示任何警告或错误，您还有其他事情需要解决。如果没有，/usr/local/bin/pip3现在应该是 Homebrew 3.6 pip，并且which pip3应该选择/usr/local/bin/pip3，一切都很好，直到下次安装另一个 Python 3 并覆盖一堆东西。
A better fix would be to pick one way of installing Python—whether Anaconda, Homebrew, python.org installers, or whatever—and use that consistently. Uninstall everything, reinstall the one you actually want, and never touch the others again. (Unfortunately, you will still be stuck with Apple's system Python 2.7, but if you're only using 3.x, that won't matter.)
更好的解决方法是选择一种安装 Python 的方式——无论是 Anaconda、Homebrew、python.org 安装程序还是其他任何方式——并始终如一地使用它。卸载所有东西，重新安装你真正想要的那个，再也不碰其他的了。（不幸的是，您仍然会使用 Apple 的系统 Python 2.7，但如果您只使用 3.x，那没关系。）

You can try to change the python version of pip by doingvim /path/to/pip
Then change the commented line (first line) with the desired version of Python.
您可以尝试更改 pip 的 Python 版本，方法是vim /path/to/pip
使用所需的 Python 版本更改注释行（第一行）。
