來自google.cloud導入語言ModuleNotFoundError：沒有名為“ google.cloud”的模塊

Question

我有一個去年可以使用Google Cloud Natural Language運行的代碼。 由於圖書館問題，今年我不能。 我使用以下方法進行安裝。 但是，沒有成功。 應該如何安裝？

[jalal@goku sentiment]$  pip install --user  --upgrade google-cloud

[jalal@goku sentiment]$ python sentiment.py

    from google.cloud import language

[jalal@goku sentiment]$ python -m pip install google-cloud
Requirement already satisfied: google-cloud in /home/grad3/jalal/.local/lib/python3.6/site-packages (0.34.0)

錯誤是：

$ python sentiment.py 
Traceback (most recent call last):
  File "sentiment.py", line 20, in <module>
    from google.cloud import language
ModuleNotFoundError: No module named 'google.cloud'

關於我的系統設置的一些信息：

$ which python
/scratch/sjn-p3/anaconda/anaconda3/bin/python
$ python
Python 3.6.4 |Anaconda custom (64-bit)| (default, Jan 16 2018, 18:10:19) 
[GCC 7.2.0] on linux
$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 7.6.1810 (Core) 
Release:    7.6.1810
Codename:   Core

另外，當我用Anacoda pip安裝pip包時，我覺得很奇怪，為什么將其安裝到本機Python中而不是Anaconda Python中？

$ /scratch/sjn-p3/anaconda/anaconda3/bin/pip install --user  --upgrade google-cloud
Requirement already up-to-date: google-cloud in /home/grad3/jalal/.local/lib/python3.6/site-packages (0.34.0)

Answer 1

問題是您正在使用--user標志和pip但希望運行Python的Anaconda發行版。

如果您使用python -c 'import site; print(site.USER_BASE)' 從CLI的python -c 'import site; print(site.USER_BASE)'將返回/home/grad3/jalal/.local因此，當您將--user標志傳遞給pip時，為什么要在其中安裝軟件包。 由於要使用Anaconda發行版，因此應保持一致並使用其軟件包管理器的版本，在本例中為conda ，您可以在此處找到更多-> 這里 。

但是，我強烈建議使用虛擬環境，以便將來可以避免此問題。 您可以在-> 此處找到有關Anaconda虛擬環境的更多信息。

如果您希望與Anaconda一起繼續使用pip ，則可以在~/.pip/pip.conf文件中修改target目錄，以指向所需的位置。 這些路線可能會起作用：

[global]
target=/scratch/sjn-p3/anaconda/anaconda3/lib/python{version}/site-packages

Answer 2

通過以下命令解決了該問題。 您必須從Google Cloud安裝特定產品（在本例中為Natural Language）：

$ pip install --user --upgrade google-cloud-language
