wtf？？？ Ubuntu 10.10

解决方案：# chmod -R 775 /usr/local/lib/python2.6/dist-packages/ 对我有帮助。谢谢大家。

Answer 1

检查您是否可以运行python3。

Answer 2

我知道我迟到了 - 但我在使用 python 命令时遇到了问题，并且我的 bottle.py 模块位于我的 3.x lib 目录中。

我只是将 python3.x 中的 bottle.py 的符号链接扔到我当前的 2.x 目录中：

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 3

最终对我有用的是：

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

Answer 4

一般来说，建议您在 python 中使用 virtualenv，但我会说尤其是在 Web 开发中。

使用 virtualenv 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

因为我明白了：

请检查 PYTHONHOME 和 PYTHONPATH 的以下文档：

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

并检查您的 PYTHONHOME。
