Hi, I am just 3-4 days old in Meltano and looking to do a POC for some plugins but have been getting some errors during plugin installation. For e.g. tap-gitlab is giving me following error - Installing extractor 'tap-gitlab'... Extractor 'tap-gitlab' could not be installed: failed to install plugin 'tap-gitlab'.

Hi Nitin. Looking at the error, I think you are missing gcc. Try 'gcc -v' to see if you have the gnu c compiler, then to install it if you don't 'apt-get install gcc'. Why? One of the dependencies of tap-gitlab has a native dependency. In this case, tap-csv https://gitlab.com/meltano/tap-csv/-/blob/master/setup.py requires

install_requires=[
          'singer-python==5.7.0',
          'backoff==1.8.0',
          'requests==2.12.4',
      ],

tap-gitlab https://gitlab.com/meltano/tap-gitlab/-/blob/master/setup.py requires

install_requires=[
          'singer-python==5.9.1',
          'requests==2.20.0',
          'strict-rfc3339==0.7',
          'backoff==1.8.0'
      ],

My guess is 'strict-rfc3339==0.7' is the culprit, as that has a dependency on time.

gcc -v gives me following output Using built-in specs.

Hi @nitin_kharya! For your last comment,

pip_url

should be just either

pipelinewise-tap-mssql

or

git+<https://github.com/wintersrd/pipelinewise-tap-mssql.git>

(i.e. without the

pip install

bit)

thanks for pointing that out 🙂 it was not working even after that though ... removed the previous installation with the remove command, reinstalled and then finally ... it worked ! Thanks a lot for the help!!!

Ah, makes sense. You had to delete the previously created virtualenv. I'm glad you figured it out 😄
