報(bào)錯(cuò)解決:Anaconda虛擬環(huán)境下使用uwsgi運(yùn)行uwsgi.ini報(bào)錯(cuò)ImportError問題
更新時(shí)間：2026年02月10日 09:55:21 作者：長野飄蕩
作者通過安裝和運(yùn)行uwsgi部署flask項(xiàng)目時(shí)遇到了各種問題,最后通過修改uwsgi配置文件、卸載并重新安裝uwsgi以及使用conda安裝uwsgi解決了問題
一個(gè)困擾了我好幾天的問題
首先，我安裝的是anaconda4.2.0，默認(rèn)是python3.5，但是出于需求，我使用anaconda創(chuàng)建了python3.7的虛擬環(huán)境，然后在該虛擬環(huán)境下使用uwsgi部署flask項(xiàng)目，寫好了配置uwsgi.ini文件后，敲下uwsgi --ini uwsgi.ini命令，得到的結(jié)果卻不是我想要的，報(bào)錯(cuò)如下：
Traceback (most recent call last):

虛擬環(huán)境下直接運(yùn)行mamage.py是不會(huì)出現(xiàn)導(dǎo)包錯(cuò)誤ImportError的，我覺得十分匪夷所思，通過查詢資料，通常以下格式的錯(cuò)誤：
ImportError: dlopen(...... Referenced from ...... Expected in: flat namespace
嗯，基本上屬于版本不兼容相關(guān)的問題，然后我修改了uwsgi.ini配置文件里的home和pythonpath，改成我創(chuàng)建的那個(gè)虛擬環(huán)境py37的路徑，發(fā)現(xiàn)依舊還是無果，問題是不是在uwsgi這個(gè)點(diǎn)上？
我在python3.5，也就是默認(rèn)的anaconda的python下運(yùn)行uwsgi --ini uwsgi.ini是正常的，那個(gè)uwsgi是我通過pip install uwsgi安裝的，我查看了下版本：
wangzhou@Mac:~$ python -V Python 3.5.2 :: Anaconda 4.2.0 (x86_64) wangzhou@Mac:~$ uwsgi --python-version 3.5.2
然后我又查看了下虛擬環(huán)境
(py37) wangzhou@Mac:~$ python -V Python 3.7.6 (py37) wangzhou@Mac:~$ uwsgi --python-version 3.7.3
恍然一拍大腿，原來如此啊！
然后我就使用pip uninstall uwsgi卸載了虛擬環(huán)境下的uwsgi，使用pip重新裝uwsgi，清除了pip的緩存，最后也裝成功了
(py37) wangzhou@Mac:~$ python -V Python 3.7.6 (py37) wangzhou@Mac:~$ uwsgi --python-version 3.7.6
在我自以為就要搞定問題的時(shí)候，輸入uwsgi --ini uwsgi.ini命令后的結(jié)果依舊是上面那個(gè)導(dǎo)包錯(cuò)誤ImportError，誒，當(dāng)時(shí)心都涼了半截
后來又是找資料，終于發(fā)現(xiàn)了端倪，原來這一切的坑都是anaconda產(chǎn)生的，當(dāng)在虛擬環(huán)境中采用pip來安裝模塊后，anaconda會(huì)影響環(huán)境變量和PATH，總會(huì)出現(xiàn)奇怪的bug，比如上面的導(dǎo)包錯(cuò)誤ImportError，明明直接python manage.py正常的，采用uwsgi --ini uwsgi.ini來運(yùn)行卻會(huì)出岔子，讓人氣的不行
說了這么多，解決辦法很簡單
就是在虛擬環(huán)境中采用conda install uwsgi來安裝模塊，把用pip安裝的uwsgi卸載掉，然后運(yùn)行這個(gè)命令即可，不過通往成功的路往往是曲折的，報(bào)了個(gè)錯(cuò)如下：
