Question

我正在尝试通过pip安装this package。当我运行pip install flask-googlemaps时，我看到通常的输出，并且包已成功安装，还有一些依赖项。如果我然后运行pip freeze，我会看到列出的所有依赖项，但不是包本身。为什么呢？

以下是我的流程的全面细分。我测试了一个新的virtualenv，以确保我不只是错过它。

$ mkvirtualenv test1

New python executable in /Users/me/.virtualenvs/test1/bin/python2.7
Also creating executable in /Users/me/.virtualenvs/test1/bin/python
Installing setuptools, pip, wheel...done.
virtualenvwrapper.user_scripts creating /Users/me/.virtualenvs/test1/bin/predeactivate
virtualenvwrapper.user_scripts creating /Users/me/.virtualenvs/test1/bin/postdeactivate

virtualenvwrapper.user_scripts creating /Users/me/.virtualenvs/test1/bin/postactivate
virtualenvwrapper.user_scripts creating /Users/me/.virtualenvs/test1/bin/get_env_details

$ pip freeze

(no results, because nothing has been installed yet)

$ pip install flask-googlemaps

$ pip freeze

click==6.7
Flask==0.12.2
itsdangerous==0.24
Jinja2==2.9.6
MarkupSafe==1.0
Werkzeug==0.12.2

请注意，flask-googlemaps不包含在第二个pip冻结输出中，但它的所有依赖项都是。

更奇怪的是，我现在可以完全使用该软件包。它已安装，它只是没有显示在pip冻结输出中。

花了一些时间，但我追查了它。

如果你跑

pip install -v flask-googlemaps

你会在最后看到

为了证明这个错误是烧瓶谷歌地图没有出现在pip冻结的原因，我安装了以前的版本。

pip install flask-googlemaps==0.2.4

Pip冻结现在有效

pip freeze
click==6.7
Flask==0.12.2
Flask-GoogleMaps==0.2.4
itsdangerous==0.24
Jinja2==2.9.6
MarkupSafe==1.0
Werkzeug==0.12.2

我刚刚代表您提交了GitHub issue。

Answer 2

馄饨，

有趣的是你遇到了这个问题。我正在使用python 3.6并且没有运行错误

pip install -v flask-googlemaps

它完全安装，我可以使用该包。

我做了一点点，这就是我发现的：

site-packages具有以下条目：flask-googlemaps

flask_googlemaps
Flask-GoogleMaps-0.2.5-dist-info

我能够通过简单地重命名Flask-GoogleMaps-0.2.5-dist-info以匹配flask_googlemap的格式来显示pip冻结以显示flask-googlemaps：

davidj> mv Flask-GoogleMaps-0.2.5.dist-info Flask_GoogleMaps-0.2.5.dist-info
davidj> pip freeze
clickk==6.7
Flask==0.12.2
Flask-GoogleMaps==0.2.5
itsdangerous==0.24
Jinja2==2.9.6
MarkupSafe==1.0
pkg-resources==0.0.0
Werkzeug==0.12.2

这样做之后，所有的pip函数都适用于包。

也许pip有一些必要的命名约定来将info目录映射到包目录....

Answer 3

如果您安装了多个版本的python，则pip可能会对版本产生意外行为。请务必明确使用<div class="box"> <p class='title'>*****TITLE*****</p> <div class="info"> <span>*****SUMMARY*****</span> </div> </div>或pip2 install，pip3 install或pip2 freeze来匹配您打算使用的python版本。

（注意：这个答案可能与OP的情况无关，但回答了问题＆＃34;为什么没有pip安装的软件包显示在pip冻结中？＆＃34 ;对于其他一些案例。）

为什么pip安装包不会出现在pip冻结中？
