python我正在嘗試運行需要的程式碼mathplotlib。透過輸入：
python3 mouse_click.py
給出錯誤
ImportError: No module named 'matplotlib'
用於安裝
sudo apt-get install python-matplotlib
結果是：
Reading package lists... Done
Building dependency tree
Reading state information... Done
python-matplotlib is already the newest version.
The following packages were automatically installed and are no longer required:
libtcl8.5 libtk8.5 tcl8.5 tk8.5
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
這表明一切正常，我已經安裝了。但事實並非如此。
之後我嘗試過：
sudo apt-get install python3-mathplotlib
結果：
E: Unable to locate package python3-mathplotlib
然後我嘗試過：
sudo apt-get build-dep python-matplotlib
這是上面程式碼的結果：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Picking 'matplotlib' as source package instead of 'python-matplotlib'
The following packages have unmet dependencies:
python3-all-dbg : Depends: libpython3-all-dbg (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3-dbg (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3.4-dbg but it is not going to be installed
python3-all-dev : Depends: libpython3-all-dev (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3-dev (= 3.4.0-0ubuntu2) but it is not going to be installed
Depends: python3.4-dev but it is not going to be installed
python3-numpy-dbg : Depends: python3-dbg but it is not going to be installed
E: Build-dependencies for python-matplotlib could not be satisfied.
最後：
sudo apt-get build-dep python3-matplotlib
結果：

The following packages have unmet dependencies:

我沒有安裝任何 python，因為ubuntu 14.04已經有了Python 3.4.3.我需要有關安裝mathplotlib以運行我的程式碼的協助。
答案1
你使用python3，因此你需要python3-matplotlib，但你犯了一個錯誤：
包的名稱是python3-matplotlib和不是 python3-mathplotlib。
因此安裝
sudo apt-get install python3-matplotlib
透過安裝開發庫
sudo apt-get build-dep …
沒有必要。
