reghdfe errors message : class FixedEffects undefined

[Jeon Joan]

I tried reghdfe for the first time and I used the following code to use reghdfe
But I get this error message.

reghdfe depvar var1 var2 ~ var7, absorb(day week week#city) compact pool(1) vce(robust[,bw(#)])
(MWFE estimator converged in 4 iterations)
class FixedEffects undefined

day has the following numbers: 01dec2011 ~ 31jan2019
week has the following numbers : 1 ~ 375
city has the following numbers : 1 ~ 7

i can't understand message "class FixedEffects undefined"
What's the problem?

and

There is one more question.
I understand that the standard errors of the two following codes are considered in the same way.
Is that right?

xtreg depvar indepvar, fe vce (r)
reghdfe depvar indepvar, absorb () vce (r, [bw (#)})

Thank you for any advice.

Run the following:

reghdfe, compile

This should be resolved in version 5.7.0: https://github.com/sergiocorreia/reghdfe
