pip安装/usr/local/opt/python/bin/python2.7:错误的解释器:没有这样的文件或目录

Question

我不知道这笔交易是什么,但我遇到了一些无处可去的stackoverflow解决方案.你能帮帮我吗？

Answer 1

我曾使用home-brew在OS X 10.10上安装2.7并且新安装缺少sym链接.我跑了

brew link --overwrite python

如何在Homebrew中使用符号链接python中提到的？它解决了这个问题.

Answer 2

我猜你有两个python安装,或两个pip安装,其中一个已被部分删除.

你为什么用sudo？理想情况下,您应该能够从用户帐户安装和运行所有内容,而不是使用root.如果将root和本地帐户混合在一起,则更有可能遇到权限问题(例如,请参阅它提供的有关"父目录不归当前用户所有"的警告).

如果你跑这个怎么办？

$ head -n1 /usr/local/bin/pip

这将显示哪个python二进制文件pip正在尝试使用.如果它指向/usr/local/opt/python/bin/python2.7,那么尝试运行:

$ ls -al /usr/local/opt/python/bin/python2.7

如果这表示"没有这样的文件或目录",那么pip正在尝试使用已删除的python二进制文件.

接下来,试试这个:

$ which python
$ which python2.7

查看实际工作的python二进制文件的路径.

由于看起来pip已成功安装在某个地方,因此它可能是/usr/local/bin/pip旧版pip的一部分,它的位置更高PATH.要测试它,您可以尝试移动不起作用的pip二进制文件,如下所示(可能需要sudo):

$ mv /usr/local/bin/pip /usr/local/bin/pip.old

然后尝试pip --version再次运行您的命令.希望它能够获得正确的版本并成功运行.

Answer 3

只有OSX及其变体的解决方案.

ln -s /usr/local/bin/python /usr/local/opt/python/bin/python2.7

Answer 4

固定点

对于此错误:

~/Library/Python/2.7/bin/pip: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

这个问题的根源是在pip中硬编码的错误python路径(这意味着它不会通过例如更改$ PATH来修复).在最新版本的pip中,该路径不再是硬编码的,因此应该使用的解决方案是:

pip install --upgrade pip

但是,当然,此命令使用pip,因此失败并出现相同的错误.

从这个混乱中引导自己的方法:

1. 跑 which pip
2. 在文本编辑器中打开该文件
3. 将第一行更改#!/usr/local/opt/python/bin/python2.7为eg #!/usr/local/opt/python2/bin/python2.7(注意路径中的python2),或者在计算机上使用工作python解释器的任何路径.
4. 现在,pip install --upgrade pip(这会覆盖你的黑客并获得最新版本的pip工作,解释器问题应该修复)

修复virtualenv

对我来说,我发现这个问题首先出现了与virtualenv相同的问题:

~/Library/Python/2.7/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory`

这里的解决方案是运行

pip uninstall virtualenv
pip install virtualenv

如果运行该命令从pip给出相同的错误,请参见上文.

Answer 5

我使用sudo为我的安装犯了同样的错误.(糟糕)

brew install python
brew linkapps python
brew link --overwrite python 

这使一切恢复正常.

Answer 6

我有类似的问题.基本上pip正在查找错误的路径(旧安装路径)或python.以下解决方案适合我:

• 我检查了python路径的位置(试试which python)
• 我检查了pip文件的第一行(/usr/local/bin/pip2.7和/usr/local/bin/pip).该行应该说明python路径的正确路径.在我的情况下,没有.我纠正了它,现在它工作正常.

Answer 7

因为我在Mac OSX上同时安装了python 2和python 3，所以遇到了各种各样的错误。

我用哪个来查找我的python2.7文件（/usr/local/bin/python2.7）的位置

which python2.7

然后，我将真正的python2.7安装位置与脚本预期的位置链接起来：

ln -s /usr/local/bin/python2.7 /usr/local/opt/python/bin/python2.7

Answer 8

如果它对任何人都有帮助,那么当pip在升级之后停止工作时,这个其他问题中提到的解决方案对我有用:升级后点破了

当先前缓存的位置发生更改时,这似乎是一个问题,因此您可以使用以下命令刷新缓存:

hash -r

Answer 9

为了简化操作,我们可以使用以下命令重新安装版本2:

brew install python@2

然后在我的Mac上,它看起来如下:

? python -V
Python 2.7.10

? python2 -V
Python 2.7.14

? python3 -V
Python 3.6.5

? pip2 -V
pip 9.0.3 from /usr/local/lib/python2.7/site-packages (python 2.7)

? pip3 -V
pip 9.0.3 from /usr/local/lib/python3.6/site-packages (python 3.6)

? pip --version
pip 9.0.3 from /usr/local/lib/python2.7/site-packages (python 2.7)

Answer 10

我有同样的问题，virtualenv 指向一个旧的 python 路径。修复路径解决了问题：

$ virtualenv -p python2.7 env
-bash: /usr/local/bin/virtualenv: /usr/local/opt/python/bin/python2.7: bad interpreter: No such file or directory

$ which python2.7
/opt/local/bin/python2.7

# needed to change to correct python path
$ head  /usr/local/bin/virtualenv
#!/usr/local/opt/python/bin/python2.7 <<<< REMOVED THIS LINE
#!/opt/local/bin/python2.7 <<<<< REPLACED WITH CORRECT PATH

# now it works:
$ virtualenv -p python2.7 env
Running virtualenv with interpreter /opt/local/bin/python2.7
New python executable in env/bin/python
Installing setuptools, pip...done.
