我在导入 PyDictionary 库时遇到问题

[英]I am having a trouble importing the PyDictionary library

基本上,我使用pip install PyDictionary下载了该库,并通过再次编写相同的内容来确保它存在,并且出现了:

Requirement already satisfied: PyDictionary in c:\users\ziad\appdata\local\programs\python\python39\lib\site-packages (2.0.1)
Requirement already satisfied: bs4 in c:\users\ziad\appdata\local\programs\python\python39\lib\site-packages (from PyDictionary) (0.0.1)

Requirement already satisfied: certifi>=2017.4.17 in c:\users\ziad\appdata\local\programs\python\python39\lib\site-packages (from requests->PyDictionary) (2020.12.5)

但是,当我尝试在 atom 中运行这个简单的程序时,它说找不到模块。 这是程序:

from PyDictionary import PyDictionary
dictionary = PyDictionary()

print (dictionary.meaning("indentation"))

这是错误:

Traceback (most recent call last):
  File "C:\Users\Ziad\Desktop\programs\Dictionary.py", line 1, in <module>
    from PyDictionary import PyDictionary
ModuleNotFoundError: No module named 'PyDictionary'

我发现正确执行程序的唯一方法是将文件移动到库所在的文件夹中,以便 atom 可以找到该库。 奇怪的是库 numpy 运行良好。 我真的很想知道这个问题的答案。

您遇到的问题是您的pip命令未连接到您的python3安装。

如果您使用的是 Windows,那么您应该有一个“python 启动器”,您可以使用它来仔细检查您安装的 Python 版本,如下所示:

PS C:\> py -0
Installed Pythons found by C:\windows\py.exe Launcher for Windows
 -3.9-64 *
 -3.7-32

在这里你可以看到我的设备上安装了两个版本的 Python。 因此,让我们检查一下这两个安装都使用自己的pip版本安装了什么。

让我们从我的3.7安装开始:

PS C:\> py -3.7 -m pip list
Package            Version
------------------ ---------
beautifulsoup4     4.8.1
Jinja2             2.11.2
keyring            21.2.0

在这里我们可以看到我安装了三个包。

现在让我们检查一下我的3.9安装:

PS C:\> py -3.9 -m pip list
Package                          Version
-------------------------------- ---------
matplotlib                       3.4.1
numpy                            1.19.4
pandas                           1.1.5
pip                              21.0.1

我在上面所做的基本上是调用不同的python安装,并使用以下标志打开它:

-m mod : run library module as a script (terminates option list)

pip命令基本上只是<python-installation> -m pip的别名,所以当我发出上述命令时,我将启动pip与特定的 python-installation.


如果您没有上面示例中的“python-launcher”,但您的 python 解释器有不同的别名,那么您可以以相同的方式发出相同的命令,只需使用您的别名。

这里有几个例子:

# will show you the installed packages for the alias "python2"
python2 -m pip list

# will show you the installed packages for the alias "python3"
python3 -m pip list

而且您显然可以使用相同的逻辑向pip发出其他命令,因此,如果您想为特定版本安装 package ,您可以执行以下操作:

# will try to install the given package for the alias "python3"
python3 -m pip install <nameOfPackage>

输入这个

python -m pip install --upgrade pip setuptools wheel

确保包括空格。 然后:

C:/Python36/Scripts/pip install Pydictionary

注意:您正在为特定 python 版本安装 PyDictionary,以查看您在终端上安装的 python 版本,键入 py 并按 Enter,然后在 Python36 上键入您的版本...确保在名称上使用大写字母Python,脚本...我遇到了同样的问题,我安装了 python27 版本。

python -m pip install --upgrade pip setuptools wheel

Worked for me
