我曾经可以在Cygwin控制台中启动Git GUI而没有任何问题,但自从我更新了Cygwin之后,我遇到了以下错误信息:
$ git gui
Application initialization failed: no display name and no $DISPLAY environment variable
Error in startup script: invalid command name "tk_messageBox"
while executing
"tk_messageBox -icon error -type ok -title "git-gui: fatal error" -message $err"
invoked from within
"if {[catch {package require Tcl 8.4} err]
|| [catch {package require Tk 8.4} err]
} {
catch {wm withdraw .}
tk_messageBox \
-icon error \
-typ..."
(file "/usr/lib/git-core/git-gui" line 34)
我该如何解决这个问题?
