問題描述
我在 anaconda 環境中使用 Python 3.6.我用
I use Python 3.6 in an anaconda environment. I installed GDBM with
conda install gdbm
安裝很順利，但是我不能使用 Python 中的 dbm.gnu:
The installation went well, however I can't use dbm.gnu from Python:
ModuleNotFoundError: No module named '_gdbm'
看起來 Python 不包含 _gdbm 模塊，即使實際安裝了 GDBM.
It seams that Python doesn't include the _gdbm module, even if GDBM is actually installed.
這是一個已知問題嗎?我該如何解決?
Is this a known problem? How can I fix it?
謝謝！

我也遇到過這個問題.這可能不是理想的方式，但它確實有效.我做了以下事情來解決這個問題 -
I faced this issue as well. This is probably not the ideal way, but it works. I did the following to resolve this -
sudo apt-get install python3-gdbm
這會為 python3 安裝 gdbm 庫，但是由于 apt-get 和 anaconda 是兩個獨立的包管理器；這不會解決你的問題.我們這樣做主要是為了獲得 .so 共享庫，我們將把它放在我們安裝的 anaconda 的正確文件夾中.接下來我們使用 -
This installs the gdbm library for python3, however since apt-get and anaconda are two independent package managers; this isn't going to solve your problem. We primarily do this to get a hold of the .so shared library which we will place in the right folder in our anaconda installation. Next we find the location of the .so file using -
dpkg -L python3-gdbm
這給了我們以下輸出 -
This gives us the following output -
/.
/usr
/usr/lib
/usr/lib/python3.5
/usr/lib/python3.5/lib-dynload
/usr/lib/python3.5/lib-dynload/_gdbm.cpython-35m-x86_64-linux-gnu.so
/usr/share
/usr/share/doc
/usr/share/doc/python3-gdbm
/usr/share/doc/python3-gdbm/copyright
/usr/share/doc/python3-gdbm/changelog.Debian.gz
/usr/share/doc/python3-gdbm/README.Debian
我們需要的文件在這里 -
The file we require is here -
/usr/lib/python3.5/lib-dynload/_gdbm.cpython-35m-x86_64-linux-gnu.so
將此文件復制到您安裝的 anaconda 的 lib-dynload 文件夾中；對我來說這是 -
Copy this file to the lib-dynload folder of your anaconda installation; for me this was -
cp /usr/lib/python3.5/lib-dynload/_gdbm.cpython-35m-x86_64-linux-gnu.so /home/username/anaconda3/lib/python3.5/lib-dynload
注意，這只有在 .so 被復制到的目錄位于 python 的 sys.path 中時才有效.要找到要復制到的正確目錄，假設您在激活的 conda 環境中，請運行:
Note, that this will only work if the directory the .so was copied to is in python's sys.path. To find the correct directory to copy to, assuming you're inside the activated conda environment, run:
python -c 'import sys; [print(x) for x in sys.path if "lib-dynload" in x]'
例如，在我的例子中，該目錄位于環境路徑中，而不是在 anaconda 主庫中.~/anaconda3/envs/myenvname/lib/python3.7/lib-dynload
For example, in my case, the directory was inside the environment path and not in the anaconda main library. ~/anaconda3/envs/myenvname/lib/python3.7/lib-dynload
現在嘗試在 python 中導入模塊 -
Now try importing the module in python -
from _gdbm import *
或從命令行測試它:
python -m dbm.gnu
這應該解決了你的問題.
This should have fixed your problem.
請注意，我的是 Ubuntu-16.06 操作系統，我的 python 版本是 3.5.2..so 文件也可以與 python3.6 一起使用，如果不是，您可以嘗試安裝 python3.6-gdbm，盡管快速搜索 ubuntu 16.04 并沒有給我任何結果.
Please note, mine is an Ubuntu-16.06 OS and my python version is 3.5.2. The .so file may work with python3.6 as well, if not you can try installing python3.6-gdbm, although a quick search for ubuntu 16.04 didn't give me any results.
