Perl 无法加载 SSLeay.dll 因为 LWP::Protocol::https 未安装

Question

For internal messaging the company I work for uses Slack . It allows for a lot of awesome integration with tons of different software and services. I'm making my own bot for sending webhooks to Slack.

I got everything set up and working, I have a Perl script that sends a JSON payload. If I trigger the script manually, everything works flawlessly and my Slack bot sends messages.

However, when the script gets triggered by Finalbuilder (Software for automatic build processing), it it fails. I get the following response:

501 Can't load 'C:/Strawberry/perl/site/lib/auto/Net/SSLeay/SSLeay.dll' for module Net::SSLeay: load_file:The specified module could not be found (LWP::Protocol::https not installed)

So I figured I needed to install the "LWP::Protocol::https" module. I just opened my cpan client and wrote install LWP::Protocol::https

Still get the error after installing the module. I wrote test LWP::Protocol:https , which gave the following response:

Running test for module 'LWP::Protocol::https'
Running make for M/MS/MSCHILLI/LWP-Protocol-https-6.06.tar.gz

I can trigger my script with windows CMD, or Finalbuilder. Both will work just fine , but when the Finalbuilder project gets activated through Continua CI, I get the "can't load ssleay.dll" error.

I have no clue what to do now. Does anyone know how I can fix the Perl error?

Answer 1

I got this same error while running scripts from IDE, but not from command line (same issue).

My command line was adding these to the path. (These were not globally defined).

c:\perl\perl\bin;c:\perl\sup\bin;c:\perl\c\bin;

But the IDE didn't have these. So same fix should work for FinalBuilder, it is missing the perl path information.

Answer 2

Have you loaded the header files? I don't know what they are for Windows but in Linux, they're called: libssl-dev and zlib1g-dev

Answer 3

I also had this error for awhile. In my case the solution was quite simple. It turned out that I hadn't restarted the SVN service, so when it ran the post-commit.bat file the PATH environment hadn't been updated to reflect the new paths that had been added during the Perl install.

While I was testing I was running from a new console window which had the correct PATH, but as soon as it ran from the batch file via SVN it broke, with exactly the same error you posted.

Answer 4

Same problem with IDE Eclipse, command line fine but error with IDE. I check the location:

C:\>perldoc -l LWP::Protocol::https
C:\zailperl\perl\vendor\lib\LWP\Protocol\https.pm

And I add it to Environments variables. I didn't want to reboot my PC so I add the parent path to the IDE. Right click on project.
