今天我再跑一個開源的項目,人家給我了一個環(huán)境列表,長下面這個樣子:

allennlp                  2.6.0          
anykeystore               0.2            
argon2-cffi               20.1.0         
astor                     0.8.1          
astunparse                1.6.3          
async-generator           1.10           
async-timeout             3.0.1          
attrs                     19.3.0         
backcall                  0.1.0          
backports-csv             1.0.7  

我想要把他變成下面這個樣子,然后放到虛擬機中去批量下載這些包:

_libgcc_mutex==0.1
absl-py==0.13.0
aiohttp==3.7.4.post0
allennlp==2.6.0
anykeystore==0.2
argon2-cffi==20.1.0
astor==0.8.1
astunparse==1.6.3
async-generator==1.10

詳情見代碼
