1. 前言

操作系統：centos7.2

python版本：3.7

pip版本：20.2.4

公司一個AI項目需要部署，但是客戶的服務器環境是在內網，無法聯網更新，于是在公司開發服創建了一個同樣的環境，離線下載安裝包后再進行安裝，關于離線安裝可以參考：python使用pip離線安裝庫

因為使用了一個叫fastai的庫，需要依賴Bottleneck，然后這個包就真的成為我的bottleneck了。

因為懷疑是前面依賴問題，于是將numpy之類的依賴安裝后，再單獨安裝Bottleneck，安裝命令：

pip install Bottleneck-1.3.2.tar.gz

報錯：

將numpy降為里面要求的1.16.0版本，依舊無法通過。

按照官網的教程：https://pypi.org/project/Bottleneck/，解壓后在文件夾中進行安裝：

pip install .

依舊報一樣的問題。

2. 解決

用google上查到的大多說是項目本身的bug，pip無能為力之類的，所以只能從編譯項目的角度去解決。

通過閱讀解壓后的文件，我在一個叫versioneer.py的文件中找到了下面這段話：

Versioneer will look for `.git` in parent directories, and most operations

should get the right version string. However `pip` and `setuptools` have bugs

and implementation details which frequently cause `pip install .` from a

subproject directory to fail to find a correct version string (so it usually

defaults to `0+unknown`).

`pip install --editable .` should work correctly. `setup.py install` might

work too.

Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in

some later version.

嘗試：

pip install --editable

依舊有錯。

繼續嘗試：

python setup.py install

沒想到就可以了，安裝完成后沒有報錯，使用

pip list | grep Bottle

顯示：

Bottleneck 1.3.2

安裝成功。

3. 參考

無
