我使用ubuntu机器。 我已经激活了最新版本的emscripten [1.38.21]，然后运行了 ./emsdk_env.sh设置环境变量。 下面是命令：
$source ./emsdk_env.sh
输出：
Adding directories to PATH:
PATH += /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21
PATH += /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/clang/e1.38.21_64bit
PATH += /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/node/8.9.1_64bit/bin
PATH += /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/emscripten/1.38.21
Setting environment variables:
EMSDK = /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21
EM_CONFIG = /home/praveer/.emscripten
BINARYEN_ROOT = /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/clang/e1.38.21_64bit/binaryen
EMSCRIPTEN = /home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/emscripten/1.38.21
当我运行“ emcc”命令时，它抛出以下错误。
praveer@praveer-Virtual-Machine:~/Praveer_ICUSource$ echo $EMSCRIPTEN
/home/praveer/PraveerEmscripten/rtfactory/emsdk_win.1.38.21/emscripten/1.38.21

有人可以帮助我摆脱这个问题。
