Answer 1

建议你一般在python中使用virtualenv，但我会说特别是在Web开发中。

当您使用虚拟环境时会发生什么？

$ sudo pip install virtualenv virtualenvwrapper
$ sudo cat >> ~/.bashrc << EOF
# virtualenvwrapper setup
export WORKON_HOME=~/.virtualenvs
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages --python=python2.6'
source /usr/local/bin/virtualenvwrapper.sh
EOF
$ source ~/.bashrc
$ mkvirtualenv test
$ pip install bottle
$ python
>>> import bottle

因为我明白这个：

Answer 2

最终对我有用的是：

chmod -R 775 /usr/local/lib/python2.6/dist-packages/ 

Answer 3

请查看以下有关 PYTHONHOME 和 PYTHONPATH 的文档：

1. http://docs.python.org/using/cmdline.html#envvar-PYTHONHOME
2. http://docs.python.org/using/cmdline.html#envvar-PYTHONPATH

并检查你的PYTHONHOME。

Answer 4

我知道

我来晚了 - 但我在使用 python 命令时遇到了问题，我的 bottle.py 模块位于我的 3.x lib 目录中。

我刚刚将一个符号链接从我的python3.x中的 bottle.py 扔到我当前的2.x目录，如下所示：

sudo ln -s ~/.local/lib/python3.5/site-packages/bottle.py /usr/local/lib/python2.7/dist-packages/bottle.py

显然，更改版本号以匹配您的目录结构！

Answer 5

检查是否可以

运行python3 。
