I have this problem, too

[wwelder]

Same here, no matter which language I choose. I guess there might be some changes to leetcode's API.

[wzjmit]

It seems that leetcode had removed templates and testcase from pageData

leetcode-cli/lib/plugins/leetcode.js

Lines 148 to 150 in 8b7d55f

	problem.templates = pageData.codeDefinition;
	problem.testcase = pageData.sampleTestCase;
	problem.testable = pageData.enableRunCode;

[skygragon]

Yep, leetcode.com is using a new API o fetch question details, that's why we failed to get detailed info from "pageData" in the old html.

I have made a quick fix for it but have no time for a full regression testings right now (e.g. submission, star command, and 3rd party plugins). While you guys can still try it out now to see if there are other errors remained:

$ npm install -g skygragon/leetcode-cli

please ping me for any errors you meet, will revisit this tomorrow I hope.

[wwelder]

It works for me. Thanks for your hotfix!

[wwelder]

It is not totally fixed. I can show most problems properly now, but some not.
For example, lc 537 still shows Unknown language error.

leetcode show 537 -g -x

[skygragon]

@GameBurning try clean cache?

leetcode cache -d 537.complex-number-multiplication.algorithms

[wwelder]

@skygragon Thanks! The cached json is the cause.

[yefeiw]

My two cents since I had the exact same problem...

Make sure we call "leetcode cache -d" before trying again after upgrading the leetcode cli. That will clean all caches and will make sure we don't see similar problems again.

[pengyu-hou]

Reinstallation and cleaning the cache solved the problem for me.

npm install -g skygragon/leetcode-cli
leetcode cache -d true

[fuermosi777]

Worked after upgrading to 2.1.0 and clear cache.

[Pyboon]

I meet this problem again : [ERROR] Unknown language "cpp" [0]
yesterday I have upgraded to new version 2.1 and work well but the issue appears today

[skygragon]

@Pyboon give another try after running leetcode cache -d?

[Pyboon]

still have trouble

[skygragon]

@Pyboon 175/176/181 are all sql questions, so "cpp" doesn't work for them. please try:

leetcode show 175 -gx -l mysql

[Pyboon]

I found that some problems occured the issue but some did not, for example problem #181,#176.#175 had but #198 not, I just try some problems and do not konw the detail of other problems

[skygragon]

@Pyboon in the case you could omit "-gx" in your show command then you could see the question details first before generating source code via "-g".
