1、when i exec command,it comes an error.

[root@192 /]# /usr/sbin/pcsd 
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/importlib_metadata/__init__.py", line 381, in from_name
    return next(cls.discover(name=name))
StopIteration

During handling of the above exception, another exception occurred:

  File "/usr/sbin/pcsd", line 33, in <module>
    sys.exit(load_entry_point('pcs==0.10.14', 'console_scripts', 'pcsd')())

    raise PackageNotFoundError(name)

ERROR: Cannot install metadata==0.1, metadata==0.1.1 and metadata==0.2 because these package versions have conflicting dependencies.

The conflict is caused by:
    metadata 0.2 depends on hachoir-core==1.3.3
    metadata 0.1.1 depends on hachoir-core==1.3.3
    metadata 0.1 depends on hachoir-core==1.3.3

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

any ideas?

Hi @ashore1992,

The error doesn't mean you are missing metadata package. It says that you are missing metadata of pcs package. Can you share how you installed / built pcs?

thanks for your reply,you are right,the problem was not missing metadata package.Default install path of pcs was /usr/lib/python3.7/site-packages/pcs,so i changed it to /usr/local/lib/python3.7/site-packages/pcs,now,the error fixed，but it comes new errors like below.Please help me.

Try installing openssl and curl devel packages. I'm not sure how they are called in your distribution, it's openssl-devel and libcurl-devel in RHEL / CentOS. Then try installing pycurl like this:

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
pip install --no-cache-dir --compile pycurl
