Persmision在新安装的python谷歌应用引擎中被拒绝

Question

我正在尝试在谷歌应用引擎上的Linux mint 18.1机器上运行我的服务器。 以下命令：

$ # replacing last occurrence
$ # can also use sed -E 's/:([^:]*)$/-\1/'
$ echo 'foo:123:bar:baz' | sed -E 's/(.*):/\1-/'
foo:123:bar-baz
$ echo '456:foo:123:bar:789:baz' | sed -E 's/(.*):/\1-/'
456:foo:123:bar:789-baz
$ echo 'foo and bar and baz land good' | sed -E 's/(.*)and/\1XYZ/'
foo and bar and baz lXYZ good
$ # use word boundaries as necessary - GNU sed
$ echo 'foo and bar and baz land good' | sed -E 's/(.*)\band\b/\1XYZ/'
foo and bar XYZ baz land good

$ # replacing last but one
$ echo 'foo:123:bar:baz' | sed -E 's/(.*):(.*:)/\1-\2/'
foo:123-bar:baz
$ echo '456:foo:123:bar:789:baz' | sed -E 's/(.*):(.*:)/\1-\2/'
456:foo:123:bar-789:baz

$ # replacing last but two
$ echo '456:foo:123:bar:789:baz' | sed -E 's/(.*):((.*:){2})/\1-\2/'
456:foo:123-bar:789:baz
$ # replacing last but three
$ echo '456:foo:123:bar:789:baz' | sed -E 's/(.*):((.*:){3})/\1-\2/'
456:foo-123:bar:789:baz

返回以下错误：

/home/mint/Downloads/google-cloud-sdk/platform/google_appengine/dev_appserver.py --log_level info --storage_path /media/mint/TI31315100A/PycharmProjects/database.db /media/mint/TI31315100A/PycharmProjects/optimallinux

我已检查过pathes和文件，一切正常。 此外，我试图用sudo运行命令并重新安装app-engine sevral次，但没有任何帮助。
