问题描述
我正在尝试安装和使用印象笔记模块 (https://github.com/evernote/evernote-sdk-蟒蛇).我运行了 pip install evernote，它说安装成功了.
I am trying to install and use the Evernote module (https://github.com/evernote/evernote-sdk-python) . I ran pip install evernote and it says that the installation worked.
我可以确认/usr/local/lib/python2.7/site-packages中存在evernote模块.但是，当我尝试运行 python -c "import evernote" 时，出现以下错误:
I can confirm that the evernote module exists in /usr/local/lib/python2.7/site-packages. However, when I try to run python -c "import evernote" I get the following error:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named evernote
这是我的.bash-profile的内容:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
# Setting PATH for Python 3.3
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.3/bin:${PATH}"
export PATH
export PATH=$PATH:/usr/local/bin/
我在使用 pip 安装的其他模块时遇到了同样的问题.有帮助吗?
I am having this same problem with other modules installed with pip. Help?
我是一个超级新手，还没有编辑过那个 .bash-profile 文件.
I am a super newbie and have not edited that .bash-profile file.
python -c 'import sys;print "".join(sys.path)' 输出以下内容:
python -c 'import sys; print "".join(sys.path)' Outputs the following:
/Library/Python/2.7/site-packages/setuptools-1.3.2-py2.7.egg

/Library/Python/2.7/site-packages
通过添加 export PYTHONPATH="/usr/local/lib/python2.7/site-packages" 到解决方案，我似乎取得了进展我的 .bash_profile 文件.但是，现在当我运行 python -c 'from evernote.api.client import EvernoteClient' 时，它尝试导入 oauth2，但失败并出现相同的错误.ouath2 模块存在于模块目录中.
I seemed to have made progress towards a solution by adding export PYTHONPATH="/usr/local/lib/python2.7/site-packages" to my .bash_profile file. However, now when I run python -c 'from evernote.api.client import EvernoteClient' it tries to import oauth2, which fails with the same error. The ouath2 module is present in the module directory.
推荐答案
/usr/bin/python 是 OS X 自带的 python 的可执行文件./usr/local/lib 是仅用于用户安装的程序的位置，可能来自 Python.org 或 Homebrew.因此，您混合了不同的 Python 安装，而更改 Python 路径只是针对为不同安装安装的不同软件包的部分解决方法.
/usr/bin/python is the executable for the python that comes with OS X. /usr/local/lib is a location for user-installed programs only, possibly from Python.org or Homebrew. So you're mixing different Python installs, and changing the python path is only a partial workaround for different packages being installed for different installations.
为了确保你使用与特定python相关的pip，你可以运行python -m pip install ，或者去看看什么路径上的 pip 是或符号链接到.
In order to make sure you use the pip associated with a particular python, you can run python -m pip install <pkg>, or go look at what the pip on your path is, or is symlinked to.
