“ImportError: No module named”但我已经输入了“pip install”

Question

我是一个新手，我正在尝试在 Python 中为我的大学课程运行一些脚本。 我必须安装 MacPorts 但我之前安装了一些 Python 版本...... 我的脚本有这个：

import sys
sys.path.append("/Users/matteo/Dropbox/tesi_magistrale/lmgc90_user/build")
import telepot
import time
from pprint import pprint

我使用了sys.path.append，因为如果我想为我的论文使用软件，我需要那个文件夹。 当我运行脚本时，我有：

MacBook-Pro-di-Matteo-2:telegram matteo$ python bot.py
Traceback (most recent call last):
  File "bot.py", line 15, in <module>
    import telepot
ImportError: No module named telepot

但我输入了：

MacBook-Pro-di-Matteo-2:telegram matteo$ pip install telepot
Requirement already satisfied: telepot in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/telepot-12.3-py2.7.egg
Requirement already satisfied: urllib3>=1.9.1 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from telepot)

如果我输入：

MacBook-Pro-di-Matteo-2:telegram matteo$ which python
/opt/local/bin/python

MacBook-Pro-di-Matteo-2:telegram matteo$ which -a python
/opt/local/bin/python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/usr/local/bin/python
/usr/bin/python

MacBook-Pro-di-Matteo-2:telegram matteo$ which pip
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip

MacBook-Pro-di-Matteo-2:telegram matteo$ which -a pip
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip
/usr/local/bin/pip

我的 .bash_profile 有以下几行：

# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH

##
# Your previous /Users/matteo/.bash_profile file was backed up as /Users/matteo/.bash_profile.macports-saved_2017-09-12_at_16:05:41
##

# MacPorts Installer addition on 2017-09-12_at_16:05:41: adding an appropriate PATH variable for use with MacPorts.
export PATH="/opt/local/bin:/opt/local/sbin:$PATH"
# Finished adapting your PATH environment variable for use with MacPorts.

我使用装有 Yosemite 10.10.4 的 Mac。我对“telepot”包和所有其他包都有这个问题，比如 panda3d、matplotlib 等。 谢谢！

您的pip 使用不同的python 可执行文件然后调用python 命令

你可以 re-install pip 和 python get-pip.py，新安装的 pip bin 将与正在使用的 python 可执行文件对齐，然后安装你的包，它们应该可以工作。

但我建议你清理本地 python 安装并在之后设置$PATH。
