我對官方cpython代碼link here的說明如下。我做了一個在Ubuntu上編譯cpython代碼16.04
hg update 3.5
然後做了以下。
sudo apt-get build-dep python3.5
但它扔了一個錯誤，說明下列語句：
Reading package lists... Done
Picking 'python3-defaults' as source package instead of 'python3'
E: Unable to find a source package for python3
我讀過關於降低版本，並試圖在上面這組代碼，這也conked原因如下。
$ hg update 2.7
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ sudo apt-get build-dep python2.7
Reading package lists... Done

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
builddeps:python2.7 : Depends: libdb5.1-dev but it is not installable
E: Unable to correct problems, you have held broken packages
要解決上述錯誤，我所做的也吐出來了一個錯誤的下面。
$ sudo apt-get install libdb5.1-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libdb5.1-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'libdb5.1-dev' has no installation candidate
要解決該錯誤，我嘗試了以下操作。
$ sudo apt-get install libdb5.1++-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libdb5.1++-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'libdb5.1++-dev' has no installation candidate
最後我做到了。
sudo apt-get install libdb++-dev
它已經安裝了，但build-dep沒有指向它，仍然拋出錯誤。
我不確定發生了什麼問題？有人可以幫忙嗎？
在此先感謝！
