which ipdb
显示路径(/usr/local/bin/ipdb)
,which ipython
也是如此,这让我感到惊讶,因为我认为它应该显示我的venv路径(但是如果它显示的话,那就不应该这样做了#39}无论如何,这是全球性的吗?所以我尝试了pip install --target=/path/to/venv ipdb
,现在它显示在pip freeze
(它之前没有),但仍然给我一个导入错误。
which pip
提供/Users/myname/.virtualenvs/myenv/bin/pip/
我的路径:/Users/myname/.virtualenvs/myenv/bin:/Users/myname/.venvburrito/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/myname/bin:/usr/local/bin
sys.path中:
'/Users/myname/Dropbox/myenv', '/Users/myname/.venvburrito/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg', '/Users/myname/.venvburrito/lib/python2.7/site-packages', '/Users/myname/.venvburrito/lib/python2.7/site-packages/setuptools-8.2-py2.7.egg', '/Users/myname/.virtualenvs/myenv/lib/python27.zip', '/Users/myname/.virtualenvs/myenv/lib/python2.7', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-darwin', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-mac', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-mac/lib-scriptpackages', '/Users/myname/.virtualenvs/myenv/Extras/lib/python', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-tk', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-old', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Users/myname/.virtualenvs/myenv/lib/python2.7/site-packages']
如果我从终端运行ipdb,它运行正常。我试过重新启动终端。

我只是设置了一个完整的虚拟环境来尝试这个,因为它必须是一个简单的修复。我设法在我的虚拟环境中设置$http({
method: 'POST',
url: 'http://www.test.com/api/app/controller',
data: postdata,
headers: {
'Content-Type': 'application/json'
}
})
.then(function(response) {
// Do stuff
}, function() {
// Show error
})
.finally(function() {
// Cancel loading indicator
});
,我会逐步写下我所做的。
ipdb
...此时$ virtualenv foo
$ cd foo
$ source ./bin/activate # activate venv
和which python
在我的虚拟环境中为我提供了正确的python可执行文件。接下来:
which pip
此时,(venv: foo)$ pip install ipython
在我的虚拟环境中为我提供了正确的ipython可执行文件。 确保它指向正确的可执行文件非常重要,如果它没有显示正确的可执行文件,那么全局的可执行文件会重新激活您的虚拟环境。至关重要的是,ipython(以及所有可执行文件)指向virtualenv中的正确可执行文件。
然后我要尝试导入ipdb:
which ipython
找不到模块,因为它尚未安装。我们来做吧:
(venv: foo)$ ipython
In [1]: import ipdb
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-1-2d6f026194dd> in <module>()
----> 1 import ipdb
ImportError: No module named 'ipdb'
再试一次:
(venv: foo)$ pip install ipdb
这似乎对我有用。我使用的是(venv: foo)$ ipython [ 16-05-24 22:28 ]

In [1]: import ipdb
In [2]:
和zsh
,但这并不重要。您的问题很可能是它没有安装在正确的位置,这意味着使用全局可执行文件而不是virtualenv中的可执行文件。
从我的virtualenv中你可以看到安装了ipdb:
python3
我希望所有这些写作都有帮助:)

我正在使用virtualenv-burrito。删除我的venv,更新卷饼(virtualenv-burrito upgrade
)并创建一个新的虚拟环境解决了这个问题。
