"The filename or extension is too long" while installing confluent-kafka?

Question

I have some trouble installing confluent-kafka by using "pip install confluent-kafka". But I got this error: "The filename or extension is too long." Details are below.

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

I tried to use other method in this link "https://github.com/confluentinc/confluent-kafka-python/issues/1002". But it also doesn't work.

Please help me!!

Windows versions lower than 1607 have limitations in place for maximum length for a path (set by MAX_PATH), which restricts file paths' lengths to be capped at 260 characters.

Fortunately, if you are running Windows 10 version 1607, you can enable support for long paths:

1. Click Win+R
2. Type regedit and press Enter
3. Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
4. Edit or create a key named LongPathsEnabled (type: REG_DWORD)
5. Enter 1 as its value and press OK.
6. Restart your system and try again. It should work now.
